The world is overwhelmingly short-term focused, and no one really knows what the future holds as the global built-natural environment evolves. It likely will be more or less recognizable compared to today. Many of us, but not all, have enjoyed living in a high-quality built environment/standard of living while our natural environment has degraded, largely unnoticed by many. Changes to our built-natural environment will likely not happen quickly but over decades, centuries, and millennia (if this isn’t considered quickly, which is a relative term). During this time, our built-natural environment is poised for significant change, some for the worse and hopefully some for the better (World Economic Forum, 2023). There is also the Doomsday Clock, originally established with the involvement of Albert Einstein to approximate humanity’s end from nuclear weapons. It has since been expanded to include other threats, and that clock keeps moving forward toward midnight (Weise, 2023a). There are also dire predictions from credible sources and acknowledgment that it is too late to fully prevent the resulting impacts (Jazeera, 2023, Ripple et al., 2023; Sumata, 2023). These predictions include ones from a Nobel Peace Prize-winning collection of scientists and perhaps the greatest group of scientists ever assembled—the International Governmental Panel on Climate Change or IPCC (2023). The press has highlighted this report (e.g., 9News, 2023; Borenstein and Jordans, 2023; Rice and Pulver, 2023). Others forecast variations on this future, but they are not substantially different (Barrage and Nordhaus, 2023; Watts, 2023; van der Wijst et al., 2023). These are in addition to the prescient 1972 Limits to Growth projections (Meadows et al., 1972), updates and various off-shoot initiatives (Bardi and Pereira, 2022; Herrington 2022), and myriad associated efforts (We Don’t Have Time, nd) that have precipitated this four-part series. There are also more optimistic outlooks based on currently available technologies (Weise, 2023b). Although somewhat dated, one study found that not one of 150 countries meets basic needs of its citizens at a globally sustainable level of resource use (O’Neill et al., 2018). An interesting link is also provided with this citation (O’Neill et al., 2018) that provides a comparison of various resource usage for these 150 countries. Ultimately, no one precisely knows what the future holds, although the facts and trend lines of the risks to our global society, economy, and built and natural environments appear indisputable. Thus, it may be best to view these various scenarios within a “cone of possibilities” while planning and preparing for the worst.
Some projections are that sea level will rise 12 inches by 2050 (National Oceanic and Atmospheric Administration, 2022a). That’s less than 27 years from now. Ten percent of the world’s population live in coastal areas less than 32 feet above sea level (Bressan, 2021), 267 million are less than six feet above sea level, 44 percent live within about 90 miles of the coast, and eight of the ten largest cities in the world are near a coast (National Oceanic and Atmospheric Administration, 2022b). This does not consider more intense storms (marine and terrestrial) from increased heat in the oceans and the atmosphere. Biodiversity extinction continues at alarming rates (70 percent of wildlife is already lost). That diversity is the basis of a healthy planetary ecosystem for all living things, including humans.
Biodiversity encompasses the living nature in all its variety. It provides many services, including climate regulation, pollination and soil formation, decomposing wastes, provision of raw materials, and contributions to our mental and physical well-being. There are three dimensions to biodiversity: ecosystems, species, and genetics. More than 90% of biodiversity loss is caused by five drivers: land degradation and habitat destruction, resource (over) exploitation, climate change, pollution, and invasive species.”
Avice-Hyet and Petit, 2023
It’s hard to estimate other high risks, including continuing wars such as in Ukraine. The coming decade will largely find whether we will succeed or fail in maintaining a quality, built-natural environment for all within a healthy global ecosystem.
Politics may seem real (and it has a definite impact on our lives, positive and negative), but it’s not reality even though it feels like it since we’ve all been raised within economic and societal systems. The natural environment is the base reality of a livable built-natural environment including the natural resources we need to have quality lives (clean air, clean water, clean food, etc.).
Ultimately, “Mother Nature” holds the “trump card,” while the built environment and the natural resources we need will pay the price financially, economically, quality of life, and extinction of species, potentially including ourselves. Even the rich are subject to Mother Nature’s laws and behaviors. While they may be able to protect themselves from her ravages for a while, eventually, she will impact them as she has the most vulnerable. (Jazeera, 2022).
Our world is approaching a mass extinction of nature, similar to those caused by the asteroid that slammed into the Gulf of Mexico 66 million years ago, ending the Cretaceous period and the age of dinosaurs. The asteroid wiped out 75% of all life on Earth. The difference this time is that slow-motion destruction is still progressing right before our human eyes (Ramanujan, 2021). The net consequences for nature, including humans, could be catastrophic given time and events unless we take them seriously. (Cowie et al., 2022; Dryden and Duncan, 2022; Greenfield, 2023; Greshko, 2021; McGuigan, 2022). Understanding both the physical and social tipping points is critical to mitigate and avoid the worst impacts (National Academies, 2023b). One intriguing book recently released explores the contribution of social sciences in conservation and conserving biodiversity (Miller et al, 2023). A better understanding is essential considering the central role humans are playing in the Anthropocene Epoch and degradation of our global ecosystem (McCoy, 2023). Moreover, nature will help us save the planet if we let it (Carew, 2023).
The central challenge is for us as humans is to see ourselves as part of the natural world, not separate or superior to it (Figure 4). There is hope and movement in a recent initiative called the Well Being Economy Governments Partnership (Meredith, 2023). This effort seems to be growing and is one to watch. It was stunning that the President of Ireland, Michael D. Higgins, recently condemned the obsession with economic growth and urged the country to rebalance the economy, ecology, and ethics (Leahy, 2023). Valuing various aspects of nature, such as infrastructure, continues (The Editors, 2023). There are also many other ideas and efforts underway. Some of which are Reuters (2023), Rotterdam School of Management (2020), Savini (2022), Stanway (2023), U.S. Army Corps of Engineers Program Engineering with Nature (U. S. Army Corps of Engineers, n.d.), National Academies (2022), and United Nations (2023b). This does not exclude the vast number of other efforts underway (e.g., Puko, 2023). The European Union has recently established sustainability rules that will require more rigorous reporting by companies around the world (Holger, 2023). Recently, the small Pacific Island country of Vanuatu is poised to gain UN approval to seek an unprecedented legal opinion from The Hague on what obligation countries have to combat climate change (Freedman, 2023). This is another aspect to watch for how it develops. With my background in transportation, it is appropriate to give a nod to the myriad efforts in that venue (Khatib, 2023). Technology advances are also in the mix (National Academies of Sciences, Engineering, and Medicine, 2023c). It is also encouraging to see other system integration efforts, in this case, the integration of ecosystem health and public health (National Academies of Sciences, Engineering, and Medicine, 2023a). After all, we are all dependent on a healthy ecosystem.

While the science behind how and how quickly our global ecosystem will change is not precise, the risks could not be higher in dismissing the timing or severity of these changes. While world-class scientists have overwhelming evidence of the impacts and how to mitigate them (United Nations Thailand, 2023, World Economic Forum, 2022, 2023), we cannot become seduced into ignoring or reducing the urgency of arguments on the precision (Bailey, 2023) of what can be done to mitigate the greatest impacts, or outright misinformation and denials (Banerjee et al., 2021). Others, including banks (Kusnetz, 2023), have not sufficiently moved toward a more sustainable built-natural environment. Inadequate action will only increase the risks. There are confounding features of our global environment, such as net growth of Antarctic Sea ice, that has yet to be explained and appears to be acting differently than the Arctic relative to global warming (Blanchard-Wrigglesworth et al., 2022; Antarctica Journal, 2023; NASA Earth Observatory n.d.; Parkinson, 2019). This does not mean that global warming is not real, but it does point out we have a lot to understand.
Planet Earth has one global ecosystem that contains a subordinate human global society and economy. In protecting our planet Earth, re-ordering our human systems to be compatible with nature, and changing hearts and minds, we will succeed or fail—together. (Gergis, 2022; Watts, 2022).
In one final thought, I have recently realized that there is an inextricable link between the existential threats of balancing truly sustainable built-natural environments and of castes in the United States and around the world (Bakewell-Stone, 2021; Wilkerson, 2020)—a planetary crisis. Over the next 20 years, we are going to encounter a “karmic moment of truth” as to how we collectively determine the quality and direction of our world society, built, and natural environments (Isabel Wilkerson interview of 2-13-2023 on The Last Word news broadcast with Lawrence O’Donnell; World Economic Forum, 2023; Vespa, 2020). We must become a real pluralistic society in the United States and globally. Diversity in nature and humanity is the default, not a monoculture. Diversity provides deeper, more flexible, more resilient, and ultimately stronger systems.
In a world without caste, being male or female, light or dark, immigrant or native-born, would have no bearing on what anyone was perceived as being capable of. In a world without caste, we would all be invested in the well-being of others in our species if only for our own survival, and recognize that we are in need of one another more than we have been led to believe. We would join forces with indigenous people around the world raising the alarm as fires rage and glaciers melt. We would see that, when others suffer, the collective human body is set back from the progression of our species. A world without caste would set everyone free.”
Wilkerson, 2020
It is the human species that has fashioned the world in which we live, and the trends we have created. Likewise, our responsibility is to solve our built-natural environment challenges while resolving our caste issues. The United Nations (2023a, 2023b, 2023c), and many others have stoked, advocated, and advanced needed change. Still, “The 2020s will be remembered as the decade that determined the fate of humanity. We can each choose to be part of the critical mass that will change the world. And when we do, it will bring profound meaning and purpose to our lives.” (Lohan, 2023; Gergis, 2023).
Wisdom is knowing that you know nothing.”
—Socrates 399 B.C., from ‘Plato’s Apology’ (my simple interpretation: to have the humility for continuous learning and changing your thinking)
Let’s face it, the universe is messy. It is nonlinear, turbulent, and chaotic. It is dynamic. It spends its time in transient behavior on its way to somewhere else, not in mathematically neat equilibria. It self-organizes and evolves. It creates diversity, not uniformity. That’s what makes the world interesting, that’s what makes it beautiful, and that’s what makes it work.”
—Donella Meadows
If all mankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed ten thousand years ago. If insects were to vanish, the environment would collapse into chaos.”

I am in my eighth decade of existence and believe, rightly or wrongly, that I have gained some perspective on the arc of life on Planet Earth. I have been a part of our global society, and its development, through my years of local, state, national, and international experience in academia, engineering, construction, transportation, natural sciences, management, and leadership. I also enjoy building things of value, physically and metaphorically, in concert with the social, human-built, and natural environments. At my base, I consider myself a scientist, nature, and evidence-based from an early age, valuing the scientific method and, as more evidence comes forth, that conclusions may change. That is in stark contrast to the misinformation in our society today. I have lived a good life, enjoyed the natural world, and benefited from myriad developments. I am proud to have brought some built-natural environment perspective to mitigate, if not improve, our natural environment. These include recycling, asset management, environmental management, infrastructure development to reduce costs and environmental impacts, improvement of habitats and associated species outcomes, and the quality of people’s lives. Unfortunately, they don’t count for much in the greater scheme of life.
As our planet approaches a population of eight billion people (Davies, 2022) (there were about 2.5 billion in 1950 when I was born), I am reminded of the “carrying capacity” (Odom, 1971) which is familiar to ecologists, farmers, ranchers, and conservationists. That is, there is a limit to the number of individuals a habitat, including our global habitat, can sustain. Moreover, risks are growing (World Economic Forum, 2022; Wallace-Wells, 2017; Pulver and Rice, 2022). It is virtually impossible to deny the influence human beings have had on the world, even to the point of creating a new geologic epoch, the Anthropocene (Brondizio et al., 2016).
I do not recall a time as now with as much attention to our natural environment since the days of Rachel Carson’s Silent Spring in 1962, the United Nations convening the first Earth Summit (the UN Conference on the Human Environment) in 1972, and the Limits to Growth in 1972. There are myriad efforts that have developed: Global Project Management (2023) and myriad series stemming from the 50th Anniversary of the Limits to Growth such as:
I reviewed some of these growing built-natural environment issues in a series of previous blogs entitled “The Mobility Ecosystem: the changing landscape and need for fresh, new ideas” (www.leadershipintransportation.com).
I was shocked to learn that the “Lungs of the Earth” (aka the vast Amazon Rain Forest) has reversed behavior. For the first time in its existence, the Amazon now emits more CO2 than it absorbs due to large-scale human disturbances such as land clearing (Gatti et al., 2021; McCoy, 2022). This is in addition to continuing degradation and destruction of the Amazon (Watts, 2022). We are also living in the sixth mass extinction of life on earth, partially because of our encroachment into wildlife habitats, and 2020 brought us a pandemic that completely disrupted our global society (Tollefson, 2020).
The efforts this past year are truly remarkable. Initiated partly by a review of the original 1972 Limits to Growth computer model in the book Limits and Beyond: 50 years on from The Limits to Growth. What did we learn, and what’s next” (Bardi and Alvarez, 2022). These efforts include a host of books, articles, webinars, conferences, and other venues on the subject of saving our planet. The 1972 Limits to Growth is still prescient 50 years later, not in details but in major trends.
Some other eclectic and seemingly disparate books have also influenced my thinking this past year, including Five Insights for Avoiding Global Collapse (Herrington, 2022), Earth for All: a survival guide for humanity (Dixon-Decleve et al., 2022), How to be a Stoic (Pigliucci, 2017), The Emperors Handbook (by Marcus Aurelius a translation by Scott and Hicks, 2002), The Standard for Project Management (Project Management Institute, 2021), and The Standard for Program Management (Project Management Institute, 2017). These readings, and others, set the basis for this writing. I have tried to write this to expand program and project managers’ thinking and perspectives as they are in a somewhat unique position to mitigate, if not improve, our built-natural environments. Prieto (2022a) provides another, more detailed discussion of the role of program and project managers in the climate change arena.
While I perused the book The Limits to Growth (Meadows et al., 1972) as an undergraduate and graduate student, I did not fully recognize its relevance.
Now, I find myself increasingly reflecting on what has gone before and what the future will look like.
Simplicity is appropriate, even though the “devil is in the details,” in explaining inherently complex subjects, and I could find no better simple description, vice describing in words, than the figures depicting our natural-built environment challenges, existential and otherwise, as in Herrington’s book (2022). There is another good figure depicting this subject entitled “Integration of Natural Capital and Economic Capital” (Figure 1) found on the inside back cover of Odom and Barrett (2005).
FIGURE 1. Integration of Natural Capital and Economic Capital (from Odom and Barrett, 2005).
Figure 2 reflects the hierarchy of needs for our planetary existence and the fragility of life on earth if nature is relegated to the lowest priority. This has some similarities to Maslow’s well-known hierarchy of needs and human motivation to have a stable and successful life (Maslow 1943).
Figure 2. The hierarchy of needs for our planetary existence. The natural environment is what sustains life and our global society. Relegating the natural environment to the lowest priority results in a fragile ecosystem and risks global human societal existence. (Adapted from Herrington, 2022)
Money is perhaps human history’s most successful shared fiction (Goldstein, 2020). We have all been raised in an economic framework, so it feels real, but the capitalist narrative underlying our economic system is purely a human invention, which becomes clear as we replace the issues surrounding this human invention with a purely physical one, such as a threat, disease, injury, or death. In other words, the natural system is what is real and it sometimes takes a traumatic event for us to reset, or see more clearly, our priorities toward life and its attendant features (family, friends, other living things, and generally enjoying what is otherwise a short human life).
In recent decades, there have been increasing efforts to address these built-natural environment challenges and dilemmas. These include environmental laws and regulations, recycling, sustainability, ESG (Environmental, Social, Governance) programs and approaches in our society in general but also in the economic and investing arenas (e.g. Fink, 2022). These efforts are all worthwhile but it is difficult, if not impossible, to ascertain whether these largely unintentionally fragmented efforts have substantial impacts toward a more balanced built-natural environment, or if they are even measuring real impacts (Catanoso, 2022), sometimes referred to as “green-washing” (Robinson, 2022). These efforts are also not without pushback in our crazy political world (Toppe, 2022; Beals, 2023; Ramsey, 2023). ESG risks in engineering and construction must also be considered (Prieto, 2022b, 2023). Another aspect is whether our built environment will bend or break while sustaining our underlying natural environment (Woetzel et al., 2020).
I believe that our current challenges require systems thinking and a program management approach (Prieto, 2021; Project Management Institute, 2022a, 2022b). Program management is a collection of projects with a common interrelationship. What could have more interconnected relationships than our global built-natural environment?
This four-part series is not meant to be comprehensive, a prediction of the future, or a doomsday. Events are moving rapidly so this series may be lagging but the central themes remain the same. It is meant as a very broad review of our current planetary situation. What I know with certainty is that we will succeed or fail in caring for our planet—together. It is our common mother ship.
“We can’t impose our will on a system. We can listen to what the system tells us, and discover how its properties and our values can work together to bring forth something much better than could ever be produced by our will alone.” —Donella Meadows

To some extent, transportation, mobility, and its infrastructure has always been a bit of a “Rorschach test.” That is that everyone, at least every American, sees something different as to what it is, what it is supposed to do, and what they want. So it is little wonder that there is a challenge in developing a strategy, consensus, and alignment in an industry with increasing social, economic, and environmental aspects to address.
No one really knows what the future holds although there is merit in the statement that “the only way to determine the future is to invent it.” There is a premise by futurists that the future can be viewed as a “cone of possibilities” which seems a reasonable approach. A Buzz Feed internet article entitled “Futurists tell us the most amazing and scary things to expect in the future” was posted on Apple News December 3, 2020 (Spohr, 2020). Some of the future mobility is described as follows.
…thinking about BuzzFeed’s younger readers, many of whom will live to see calendar years even more mind-bogglingly futuristic, like 2080, 2090, and even 2100. What will life be like for them over the course of their lives? How many changes will they see over the next 10–80 years?
To find out, BuzzFeed connected with some of the world’s leading futurists and asked them to forecast what the years to come might bring. Here are their fascinating and thought-provoking insights:
Public transit will be radically different in the future — and traffic will be a thing of the past.
Twentieth century public transit will be replaced by private transportation in van-sized smaller vehicles and single-person pods, driving on roads that are rarely congested because everybody follows tools like Waze which work together with cities to stop too many cars bunching up in the same place before they get there.”
— Brad Templeton
Family road trips will be in self-driving recreational vehicles accessorized with robot assistants and food replicators.
Self-driving RVs will pick you up from your home and be pre-programmed to drive the route you chose (including parking themselves in the designated spaces in RV parks), and they’ll stop along the way at national parks…with reservations, of course. The RV will have internet-on-the-go to allow the kids to play computer games when the vehicle is in motion. The entertainment module will be tailored to the child’s age and interests so that you will never hear, ‘Are we there yet?’ The RVs will be equipped with food replicators, so if the parents don’t want to cook, they won’t have to. Robots will handle the setup and tear down, including making sure that the black water is flushed. All the family has to do is enjoy their time together on this all-inclusive holiday.”
— Joyce Gioia
There is increasingly speculation on the future, not to mention the impact of changing technologies on skill sets and the need to re-educate the changing workforce (Shea, 2021; Michal, 2021). Even Warren Buffet was slow to recognize the important role of technology in our society (Gandel, 2021). The point, we must remain open to change otherwise we risk getting stuck (Hawrylack, 2021). This is a dynamic in human nature.
There are also studies and ideas that have been generated such as what should the future of the interstate highway system be? (The National Academies of Sciences, Engineering, Medicine, 2018)
National Aeronautics and Space Administration or NASA innovations and products for space exploration have been adopted for use by our society. Most recently, NASAs 2020 Rover, a car sized vehicle has been developed along with a helicopter to learn more about the Martian planet (Adams, 2021). NASA developments will likely continue to add to our transportation-mobility arena and society as a whole.
While this series of blogs has dealt primarily with ground surface transportation and mobility, changes are afoot in other modes. For example, some airlines and investors are betting on electric vertical takeoff and landing aircraft (eVTOL) to replace helicopters (Subin, 2021; LeBeau, 2021). Many want an improved passenger rail system (Benson, 2021). The Elon Musk inspired Hyperloop is estimated to exceed speeds of over 700 miles per hour and there are companies around the world working to make this a reality. Still, there are technical and economic issues to overcome (Silic, 2021; Kim and McNabb, 2020). Musk has even asserted that while the California High Speed Rail costs exceed $68 billion, the Hyperloop could be built to span the same distance for $6 billion (Nicol, 2018). There is the topic of smart roads (Integrated Roadways, n.d.).
The only thing that is certain is that the transportation and mobility space is changing, and rapidly.
There are discussions, trends, and research on the departments of transportation of the future (Fuchs and Shehadeh, 2017), thinking beyond cars (Busch, 2017), automated drive-thru meals (Metz, 2021), need for greater equity (Lydersen, 2020), easing poverty (Korman, 2021), electrifying transportation for low income communities (Citizens Utility Board of Illinois, 2020), data management (Center for Digital Government, 2020), big data to relieve congestion (Neumann, 2015), getting broadband across the United States and especially rural areas (Harrison, 2021), reducing traffic congestion and saving costs using AI and V2X (V2X=vehicle to everything) technologies (Carey, 2021), 5.9 GHz (Bhatt and Tymon, 2021), 5G (Fulton, 2021; Wachsman, 2021), smart roads and inductive charging (McFarland, 2021; Stout, 2020; Integrated Roadways, n.d.), cloud services for transportation agencies (AWS, n.d.; Silver, 2021; Matteson, 2021; Silver, n.d.), increasing citizen needs for digital technology in local governments (Schiavone, 2021; Rock Solid, n.d.; Pew Research Center, 2021), growth of micromobility (Miller, 2021), reimagine delivery with drones (Drone Delivery Canada, 2021), reinventing container shipping (Saxon and Stone, 2017), changing logistics (vanValkenburgh, 2021), renewed nature-based solutions (Miller and Huber, 2021), renewed emphasis on resiliency (Schmitz, 2021), increasing environmental issues (Teirstein, 2021; Woodyatt, 2020; Phillips, 2019; Irfan, 2019), how to rebuild America’s infrastructure (Della Rocca, et al, 2017), funding (Wehrman, 2021; Lombardo, 2021), bridging infrastructure gaps (Woetzel et al, 2016), private infrastructure financing (Budden, 2017; Parsons, 2021), new innovations in project financing, delivery, and public-private partnerships (U.S. Department of Transportation Federal Highways Administration, 2021; Glazier, 2020), and many others. Others speculate on the future of mobility in cities (Harrouk, 2019), the future of autonomous vehicles in business (Gifford, 2017; Lamb, 2019), and an increasingly long line of public and private organizations committing to 100 percent electric vehicles in the next 10-20 years (Bascome, 2021), lessons in electric vehicle launches (Turkel, 2021), generator-equipped electronic vehicles (Morales, 2021), electric buses (Carroll, 2021), growing fleets of electric cabs (Lambert, 2021), electric delivery vehicles (Adams, 2021), electric heavy trucks (Reuters, 2021), design changes in electric vehicles (Korn, 2021), death of the gas-fueled vehicle (Hamza, 2021; Westbrook, 2020; van Lierop, 2020; Evannex, 2018; King, 2016), electronic vehicles will have 100% of the market by 2040 (Entrepreneur, 2021), the need for additional electric power production (Markets and Markets, 2020; Hull and Malik, 2021), new tools (Remix, 2021), some future implications of zero emission vehicles ( Robinson, 2021), expanded broadband (Pressgrove, 2021; McEwen, 2020), smart cities (Napolitano, et al, 2021), mundane mobility including sidewalks (Descant, 2021), fragility of the supply chain (Naughton and Colias, 2021; Ziady, 2021; Thorbecke, 2021), use of highway medians for other transportation purposes including monorail (Ohnsman, 2021), where Covid-19 has accelerated change (McKinsey & Company 2021), flying cars and driverless buses (Broom 2021), continuing developments in mobility technology (Heineke, et al, 2019), and the need to view infrastructure as a system (Smith, 2020). For now in the transportation space, cities are becoming greener, climate change continues largely unabated, and the impacts of the Pandemic continue with an uncertain future (Baruchman, 2021; Ariza and Harris, 2021; EPA, n.d.; The National Academies of Sciences, Engineering Medicine, 2021; vanValkenburgh, 2021b; Frueh, 2021; Lowry, 2021). These are all legitimate forward-looking “think pieces”, products, and services and are needed.
It is also important to remember we live in one world with one global economy and environment (Shalal and Lawder, 2021; Whalen, 2021; Reuters Staff, 2021).
Some aspects of these futures and ideas may materialize but they are just that, speculations on what the future of mobility may look like. What the future holds will likely be messy and not simple (Putnam, 2021; Gifford, 2017). While it can be entertaining and thought-provoking to consider these futures, no one really knows what the future holds.
To emphasize that no one really can predict the future even though many have some basis, it is interesting to look back at some predictions made only a few years ago. For example, pre-2015 (Carroll, 2014; Eaves, 2007; Frey, 2008; Threewitt, 2012) and post-2015 which is closer to what we know now (Marsh & McLennan Agency, 2018; The National Express Transit, 2019; Mire, 2019; Cunningham, 2017; Thansis1997, 2018; Goodnet, 2016; Frey, 2021). To my surprise, there are even futurist schools (The Futurist Institute). And then there are the pundits speculating on the future of transportation stocks and companies that are disrupting the transportation industry (Whiteman, 2021; Sandre, 2017).
There is the issue of what long term effects the Covid-19 Pandemic will have on transportation, mobility, and freight (Furchtgott-Roth, 2021; Polzin and Choi, 2021; Goodman et al, 2021) and warning signs of a longer pandemic (Baker, 2021).
There is also the continuous drumbeat of the need for infrastructure investment (Landers, 2021; Infrastructure Report Card, 2021). I would add to this the need for social and environmental investment since they are not mutually exclusive.
Throughout this series of blogs there has been very little attention to other areas of the transportation and mobility space such the arena of logistics and supply chains which reflect the entire system through a freight lens.
Being somewhat simplistic, we know a few things with a very high level of certainty relative to the future of transportation and mobility:
America’s transportation systems are long overdue for increased investment. As the new Biden Administration proposes massive funding initiatives for transportation infrastructure, technology will play a critical role in enabling a modernized, next-generation transportation system. A new reliable and sustainable funding model to replace the fuel tax is part of this.
Autonomous, electric vehicles, V2V, V2I, V2X, adaptive traffic signals, electronic tolling/user fees, advanced machine learning, artificial intelligence, 5G, and asset management tools using the Internet of Things, will all be foundational building blocks of a modern system.
A modernized system will combat climate change and meet constituents’ changing needs, including equity, social and environmental justice.
These systems will require a fresh approach to how information is acquired, managed and analyzed as they require the processing of petabytes of data in real time. Cloud computing and edge computing will be part of this mix considering the enormous amount of data involved.
Many are looking, exploring, and building the future of mobility and transportation, it happens a piece at a time, and like other infrastructure and systems that society depends on, is sorely needed (The Commission on the Future of Mobility, 2021). The potential for information overload is a likely risk and part of this mix, as it is presently, and must be effectively dealt with (Sammer, 2021).
The interests and impacts of transportation and mobility are vast with far-reaching impacts to our society, the economy and environment. There is likely no one that is not impacted. Although what an average family spends on transportation can vary from 13 percent to 30 percent of their income depending on various factors to include income, a common percentage used is 16 cents of every dollar, and 93% of this goes to buying, maintaining, and operating cars, the largest expenditure after housing ( Elite Personal Finance, 2021; Cautero, 2021; ITDP, 2019; Financial Samurai, 2020; Miller, 2021; U.S. Department of Transportation, Bureau of Transportation Statistics, n.d.; American Public Transportation Association, 2021).
This has been a broad, somewhat rambling, series through the mobility ecosystem and has not touched a great many areas and topics but, hopefully, has touched upon the major ones. As travelers, explorers, and citizens of the earth, we must continue our aspiration to understand and sustain our built-natural environment, and the mobility ecosystem, before they become unsustainable. This series has not given proper attention to a host or organizations (public, private, academic, and others) that are making substantial contributions toward the challenges and opportunities facing the mobility ecosystem. Some of these and associated organizations include the United States Department of Transportation and its modal administrations and offices, state departments of transportation, city and county associations, the National Academies including the Transportation Research Board, American Association of Highway and Transportation Officials and their regional associations, Intelligent Transportation Society of America, Metropolitan Planning Organizations, American Road and Transportation Builders Association, Associated General Contractors of America and their state chapters, American Council of Engineering Companies and affiliates, National Society of Professional Engineers and affiliates, National Society of Black Engineers and affiliates, Women in Transportation Society and affiliates, Women in Transportation Society International, Society of women Engineers, National Association of Women in Construction, American Society of Civil Engineers and affiliates, Society of American Military Engineers and associated posts, Green Roads, World Road Federation, International Road Federation, International Bridge, Tunnel, and Turnpike Association, Engineering News Record, American Trucking Association and state chapters, American Public Transportation Association and state affiliates, Association of American Railroads, colleges and universities including University Transportation Centers, and others. Other companies too numerous to name helping to lead the way include auto and truck manufactures, technology companies (including AI, 5G, web services, data services, edge computing), safety (National Safety Council and affiliates, American Traffic Safety Services Association, Association of Transportation Information Safety Professionals, and many others), finance agencies including bonding, other agencies (federal, state, and local), interest groups of all kinds (including the American Automobile Association), and many other important organizations that not only add to our body of knowledge through studies, reports, webinars, conferences, news and other means to advance our mutual interests reflecting a cross-section of our society, economy, and environment. My apologies for the many organizations I have not acknowledged.
Dr. “Kevin” Bao also provides an interesting perspective on how leaders should respond to crises and opportunities. (Steele, 2021). Perhaps this can help in our efforts to clearly, objectively, and urgently address the challenges ahead.
The National Academy of Engineering, National Academies, is bringing many previously disparate and fragmented disciplines and areas of scholarship of complex systems into more holistic thinking (Madhavan et al, 2020). It is challenging and difficult work to digest such broad knowledge but it is an important start to a better way forward, in transportation, mobility, and other areas. After all, a unifying characteristic of complex systems is that they are driven by human behavior, and human thinking.
Of course an elephant in the room is what impact will the $1.9 trillion Covid relief package have on our society, economy, environment, and people’s lives to include the transportation and mobility space (Pramuk, 2021; Morris, 2021).
The new Biden Administration also envisions a once in a century opportunity to change transportation—a new transportation era—comparing this opportunity to the interstate highway system started under President Eisenhower and the transcontinental railroad started under President Lincoln (Yen, 2021). As such, the Administration continues to pursue a robust $2.3 trillion infrastructure plan (Tankersley, et al, 2021). While the majority of Americans support this and there is a verifiable need, it is also a “heavy lift” considering the complexities of our modern day society and politics.
There is also the underlying discussion of how to best democratize the Internet and social media without interfering with the great good these tools provide (IoTeX, 2020; Newcomb, 2016; Smith, 2019; Edinger, 2021; Vicente, 2020; Susaria, 2021; Edinger, 2021).
Recently, the first Nobel Prize Summit was held and attended by Nobel Prize Laureates and other experts. The summit was convened to promote a transformation to global sustainability for human prosperity and equity. As was pointed out, time is the natural resource in shortest supply. This summit was established amid a global pandemic, a crisis of inequality, an ecological crisis, a climate crisis, and an informational crisis. Without transformational action this decade, humanity is taking colossal risks with our common future. The future of all life on this planet, humans and our societies included requires us to become effective stewards in creating a harmonious biosphere and society. This includes inherent infrastructure and mobility. The bottom line, there is now an existential need to build economies and societies that support Earth system harmony rather than disrupt it. In summary, we need to reinvent our relationship with planet Earth as we build this new future. (The National Academies of Sciences, Engineering, Medicine, 2021)
There is an adage that says the only way to predict the future is to invent, or create, it. There are myriad efforts in that direction. To that end we may be seeing the private sector emerging to lead that future while the public sector follows.
Which takes us back to the quote at the beginning of Part 1 in this series:
The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.”

We live in a global economy, driven by multimodal transportation across the earths surface—land, air, and water.
This writer has tried to separate into shorter sections the social, economic, and environmental issues but found separating them was artificial and not real, losing or subordinating the inter-connectivity in the process. While disciplines are important and reasonable to separate out for “deeper dives,” separating them into categories defeats the purpose of a holistic or systems view. Thus, these issues are addressed as they appear—one ecosystem, or mobility ecosystem in this case, with related parts—in at least an attempt to reflect a systems view. Segueing from Part 9, it is also worth noting that without a functioning democracy we have nothing, including meaningful progress in the transportation and mobility space and all of the issues tied to it.
While the current Covid-19 Pandemic was not caused by our global transportation system that drives our global economy, there is no question that the pandemic’s rapid spread was a result. Similarly, the “cure” will be more rapid because of this same transportation system.
The pandemic has lost some of its acceleration as counter measures and vaccinations have taken place although there is concern over variants and a race for booster vaccinations occurs, similar to annual flu vaccinations. Still, more than 30 million Americans, or one in every 12, have been diagnosed positive for COVID-19 with over 550,000 deaths in the U. S. and nearly 3 million deaths globally, as of this writing. The expectation is that the total U. S. deaths will exceed 600,000 deaths by the end of 2021, before the pandemic is “under control” in the United States. The Centers for Disease Control, or CDC, estimates the actual number of Covid-19 infections may exceed 83 million in the U. S alone (CDC, 2021). Worldwide there are currently nearly 140 million recorded cases. (Wu and Chiwaya, 2020; Worldometer, 2021; Baker, 2021).
The year 2020 was the worst year for economic growth since World War II (Siegel, et al, 2021). Moreover, there was no “playbook” of how to respond economically as we continue to try and understand and plan for the future (White, 2021; Ross, 2021; Achenbach et al, 2021). It has changed everything in our lives—how we work, how we shop, how we socialize, how we commute, how we travel, education, business, entertainment, the environment, the economy (Vasel, 2021; Reese, 2021; Lobosco, 2021; Stern, et al, 2021; Watson, 2021; Dickler, 2021; Hughes, 2021; Wikipedia, 2021; Wikipedia, 2021; Parker, 2020; Spear et al, 2020; Pesek, 2021; Burns and John, 2020; Reuters, 2021; Bauer, et al, 2020; Patton, 2020; McKinsey & Company, 2021; Craven, et al, 2021; Entrepreneur, 2021; Davidson, 2021). The Pandemic persists even as vaccinations progress; new variants emerge; some states set aside recommended CDC measures, and a potential 4th surge emerges (Khemlani, 2021; Dearman, 2021; Rodriguez, 2021; Guenot, 2021; Dilven, 2021; Diedrich, et al, 2021; Murray, 2021). This is also changing how we think about cities, remodeling them in ways that could make urban life, and rural life, more attractive and sustainable (Goldsmith, 2021). More specifically, state department of transportation leaders recently discussed the impacts of Covid-19 on transportation (AASHTO, 2021). The “15-minute city” concept is emerging around the world—dwellers should have everything they need (work, grocery stores, bars, restaurants, shops, schools, healthcare, leisure) within a 15-minute trip, on foot or bike, from home (The 15-Minute City Project, 2020; Moreno, n.d.; Sisson, 2020; Harley, 2021). To be fair, there are also concerns about the 15-minute city with potential to increase inequality (O’Sullivan, 2021). Lockdowns gave working from home proof of concept, challenging the notion that cities need to be divided into separate areas for working and living. Many city dwellers experienced life with fewer cars and more bikes on streets and those cities will have to decide whether to make these “healthy streets” permanent (Whittle, 2020). A new smart city work philosophy concept is emerging for companies—smaller workspaces to meet all over the city, closer to people’s homes. The traditional idea of a city, one where smaller communities form around one central hub, is changing. Future cities may become vast urban areas made up of several smaller communities, each with their own center.
There is also the issue of communities holding onto some of the good things that have occurred during the pandemic (Descant, 2021). Besides the Herculean effort to develop and deploy vaccines, there are many other efforts that have been generated in these dark times. In another Herculean effort, the U. S. Army Corps of Engineers led the conversion of hotels and other buildings into needed COVID-19 hospitals. They also created an intelligent HVAC system that will likely find many uses in indoor spaces, and perhaps the transportation space as well (Carter, 2021).
None of this discounts the attractiveness of living and working in rural communities because there is much to like in these wide-open, needed spaces, that produce much of the food and other products we consume. Access is through mobility in all its forms. While agriculture is main stem in rural areas, the beauty of wild spaces has an important part in the United States, the world, our psyche, mental health, health of our planet and the life that it supports (Williams, 2017; Louv, 2011).
Even as we deal with this pandemic and its impacts to our lives and economy, there is need to learn lessons and prepare for the next pandemic, including in the transportation/mobility space (Wall, 2021).
The pandemic has caused us to rethink the ways we work. Microsoft founder, Bill Gates, predicts companies will much more begin to question taking a trip “just to discuss things,” reducing business trips by more than 50 percent. Home offices have grown exponentially, turning business meetings into video calls. This way of work is likely here to stay, reducing “office life” by more than 30 percent. (Entrepreneur, 2020).
As mobility emerges as a human right, equity, social and racial justice, equality, environmental justice, and mobility for the under served, disabled, minorities, communities of color, and poor are part of the core mission for transportation agencies. Moreover, as technology evolves and holds promise for improving lives, the digital divide must be closed and made accessible and affordable to all. This is an opportunity and will require strong strategic partnerships with private sector partners such as IBM, Apple, Google, Verizon, GE, and others. These necessary public-private partnerships might include joint committees, agreements versus contracts, and collaboration with other partners and stakeholders. Transportation agencies also would be well served by having offices or positions for experts in these areas and are well integrated into planning, design, construction, operations, and maintenance activities and collaborate with other partners, interests, and departments as appropriate. Updating the American Disability Act and related laws and rules must also occur.
The February 2020 ITE Journal is dedicated to exploring equity, what it means for transportation, strategies, how to put equity at the center of our work, micromobility to reach the under served, and how to make transportation systems better for all. This is a valuable resource for transportation professionals (ITE, 2020). There is evidence that transportation and mobility can help defeat poverty (Korman, 2021). There are also emerging tools and experience for measuring and advancing equity and social values (Fujiwara and Dass, 2020; Alexander et al, 2020; Citizens Utility Board, 2018).
Dorval R. Carter, Jr., President of the Chicago Transit Authority, received the 2021 Thomas B. Deen Distinguished Lectureship from the National Academies of Science, Engineering and Medicine Transportation Research Board (TRB). Mr. Carter was recognized for his leadership in the transit industry and legal community, and for spearheading significant advances in public transportation. His presentation, “Our Work is Never Done: Examining Equity Impacts in Public Transportation”, provides an excellent narrative for where equity has been and where it is going. His presentation, given as part of the TRB’s 2021 Annual Meeting on January 25, 2021, can be viewed via YouTube at: https://youtu.be/IBMgn5Ivm3c.
Environmental justice, similar to mobility, is emerging as a human right as it should. Its premise is essentially that all people deserve to live in a clean and safe environment free from industrial waste and pollution that can adversely affect their well-being. Those involved in creating and maintaining the mobility space must take responsibility for insuring this space is accessible, affordable, and with a clean and safe environment for all, including the under -served, minorities, communities of color, poor, and dispossessed. In addition to strong environmental offices and positions, environmental laws and rules must be updated. The impacts of greenhouse gases can have impacts far from their source (TRB, 2021).
In 2020 during the pandemic, the U. S. saw a 10.3 percent reduction in greenhouse gases, the lowest drop in annual emissions since World War II. See Figure 11. (Larsen, et al, 2021). This was a result of an estimated reduction of 15 percent vehicle miles traveled (VMT) compared to 2019 and a 13-40 percent reduction in demand for primarily passenger vehicles and as much as 18 percent reduction in diesel in April and May. This also resulted in delays of many projects as transportation department revenues from fuel taxes cratered.
FIGURE 11. US Greenhouse Gas (GHG) emissions by emitting sector in million metric tons CO2. Source ClimateDeck, Rhodium.
While this allows the U. S. to exceed the 2020 Copenhagen Accord target reduction of a 17 percent below 2005 levels, this should not be considered a permanent change in meeting the 2025 Paris Agreement target of 26-28 percent reduction from 2005 levels. In addition, the 2020 reduction has come at an enormous price to the economy and human suffering. Serious work to make meaningful structural changes must continue to improve environmental health and limit global warming.
Over the past year, the world has been fixated on the pandemic and its effects on our lives, and for good reason. But an even bigger threat could change the way we live in a less rapid but more permanent way—the climate crisis—an existential and intergenerational quality of life threat. The threats range from the profound to the more subtle (Guterres, 2018; Xu, et al, 2020; Roston and Wade, 2021; Deutsche Welle, 2021; Cassella, 2021). Transportation agencies are some of the largest land owners in the world with responsibility for the land, air, and water. As such, they play a significant role in fighting climate change.
Global warming has already forced an estimated 20 million people to flee their homes every year (Oxfam, 2019; Ropeik, 2021; Newburger, 2021; NOAA, 2021). Rising temperatures combined with population growth means three billion people — one third of the projected global population — could be living in “unlivable” conditions by 2070 (Fleming, 2020). The inevitable result will be mass migration to “climate havens,” or cities sheltered from extreme weather with the capacity to grow (McDonnell and Shendruk, 2020). Preparing for this future can no longer be put off, and heads of state, members of the scientific community, the private sector, NGOs and youth groups will meet to discuss the issue at the world’s first Climate Adaptation Summit in January 2021. As cities around the globe develop climate action plans (C40 Climate Leadership Group, 2020), expect to see more zero-carbon housing projects (C40 Cities Climate Leadership Group, Nordic Sustainability, 2019) and green belts replacing asphalt (Totaro, 2020). “The questions we should be asking is how to protect the most vulnerable residents,” says Greg Lindsay, Director of Applied Research at the nonprofit NewCities Foundation. “How to develop new carrot-and-stick approaches to steer people away from the highest-risk areas.” (Lindsay, 2020).
Florida is ground zero for sea level rise and the costs are rapidly escalating into the multiple billions of dollars. Miami is raising their roads two feet and others are preparing to abandon, roads, bridges, and homes (Mitchelides, 2016; Harris, 2019; The Weekly Staff, 2020; Carroll, 2021; Sea Level Rise.org, n.d.). Rising sea levels are threatening Route 1 through the Florida Keys. The costs of raising the roads will amount to $500,000 per resident according to an a narrative without reference (Latanision, 2020). Regardless, published reports state some roads would cost $25 million per mile to adjust for sea level rise (Brackett, 2019). Using that cost and that US1 is 113 miles long over the Florida Keys with an estimated population of 73,000, the cost would be about $40,000 per person. Regardless of which is more reliable, these costs will likely continue to grow and ignore other impacts such as abandoned homes and businesses, property being flooded and below sea level, and ultimately a cost the State of Florida cannot afford.
Florida is not the only location at risk due to the rise in sea level. New Orleans is a case in point where it has been below sea level for many years—protected by sea walls and gigantic U. S. Army Corps of Engineers pumps (Twillie, 2018; Prior, 2019; Dunn, 2020; Laskow, 2017). Add to this that by 2050 70 percent of the world’s population is estimated to live in large cities, and these cities are sinking, literally, under their own weight (Parsons, 2021; Koop, 2021; Department of Economic and Social Affairs, 2018). The cumulative effects of storms, land subsidence, and urban cities subsidence could have dramatic impacts on life and the way we live, including transportation and mobility since they are never mutually exclusive from the built-natural environment. Soils have elastic and plastic properties. There is a propensity for cities to expand development through building new land with fill material, on wet soils, or adjacent to water bodies. Thus, it is relatively easy for these saturated soils to be prone to liquefaction, especially in seismically active areas. This is made worse by infrastructure, including roads and bridges, not being seismically designed or retrofitted (Chalmers, 2018; Oregon.gov, 2013). This writer is reminded of the many studies on the risks and catastrophes of building on permafrost, helping to better understand the built-natural environments, including before construction of the Alaskan Oil Pipeline (Péwé, 1979). Engineering has limitations and we frequently learn as we go, or hopefully.
Climate change has resulted in billions of dollars in flood damage (National Centers for Environmental Information, Feb 2021; National Centers for Environmental Information, Jul 2021; Kann, 2021). There is also the threat of land subsidence that may affect 19 percent of the world population by 2040 (Herrera-García, et al, 2021).
There are yet other issues that are likely to have negatives impacts. As many as 572 airports are also threatened by global warming and associated sea level rise by 2021 (Yesudian and Dawson, 2020). A record number of hurricanes, wildfires and floods cost the world $210 billion in damage in last year, much of it due to global warming. There were a record number of disasters during 2020 which occurred in the U.S. (NOAA, 2021).
This does not even mention the many negative impacts to a healthy environment (some of which were mentioned in earlier blogs of this series) that we depend on and continue to emerge (World Wildlife Fund, 2021; Rosane, 2021; World Wildlife Fund, Feb 2021). There are also many negative impacts to our environment, including from global warming, but some may not be attributed directly to climate change (Burt, et al, 2018; University of California – Santa Cruz, 2021; PEW, 2020; McPherson, et al, 2021). .
The recent winter infrastructure crisis in Texas is indicative of the importance and cost of infrastructure upon which society depends. In many cases, the repair, replacement, updating, contingency planning and preparation has been deferred, delayed, and perhaps overtly ignored for decades. This has been made worse by the impacts of climate change (e.g. changing weather patterns, warming/acidic oceans, etc.). Millions of people have gone without power, electricity, heat, water, waste water services, transportation and mobility for days, in some cases weeks. Fish and wildlife have also suffered. This is largely avoidable, if not substantially mitigated, by relying on science and proactive planning. This catastrophe has also impacted other states and communities. This human catastrophe is a failure of leadership. It is a virtual certainty that we will see more of these built-natural environment catastrophes in the United States and around the world. And, it is the most vulnerable, poorest and least able to cope that will suffer the most. (Gonzalez, 2021; Giusti, 2021; Meier, 2021; Fowler, 2021).
Defining carbon zero by 2050 targets, as well as roles and responsibilities, is yet another area that must be clarified and is critical to addressing the challenges of climate change in the United States and around the world (Buddoo, 2021; National Academies of Sciences, Engineering, Medicine, 2021; Global Carbon Project, 2015-2020).
The Internet of Things, or IoT, holds promise to mitigate and improve other climate changes in other ways such as biodiversity and habitat loss (McClellan, 2020). Ecological bridges, essentially bridges over roads or other man-made structures, serve to connect wildlife habitat, connect and sustain gene pools necessary for healthy ecosystems (Hui Min and Pazos, 2015; Machemer, 2020). Otherwise gene pools become fragmented, exacerbating the challenges of habitat and species loss due to climate change.
While this author was a researcher at the U. S. Army Corps of Engineers Waterways Experiment Station, the Corps adapted a Wetlands Evaluation Technique developed by Paul Adamus for the Federal Highways Administration (Adamus, 1983). The valuing of nature has continued to evolve to the present. More recently, Dow Chemical Company and The Nature Conservancy developed a technique called the Ecosystem Service Identification and Inventory Tool that is available publicly (www.esiitool.com). This technique quantifies ecosystem services using a nature screen and a nature scoreboard to develop the business case for using nature in lieu of or in conjunction with other man-made systems. Dow has committed to generating $2 billion of value to nature, having achieved $500 million thus far. This system continues to evolve as do the efforts of private and public organizations in creating a sustainable world. On the horizon are what have been termed “stacked benefits.” That is, bringing together many partners, from up stream and downstream, so to speak, to pool resources and funding toward a greater benefit to the natural and built environments. This is part of Dow’s commitment to identify $1 billion in net present value through their Valuing Nature Goal, and work processes developed to support the goal, as well as challenges and successes in driving culture change (Polzin and Molnar, n.d.; Engineering with Nature, 2021).
Recently, the Federal Emergency Management Agency (FEMA) intends to funnel up to $10 billion into preventing climate disasters, the most ever, preemptively protect against damages by building sea walls, elevating and moving flood-prone homes and businesses, and other steps as climate change intensifies storms and other natural disasters—“Building Resilient Infrastructure and Communities or BRIC”. While this is an important step, it is doubtful this will be enough given the costs that climate change will exact. The U. S. Army Corps of Engineers National Nonstructural Committee (NNC) has had a relocation program from flood plains and other areas prone to natural flooding and that has met with some success but resistance as well (National Nonstructural Committee). There is a continuing discussion of resilience (Campbell, 2021). There is the idea of “seasteading”, houses and other buildings built on floating platforms that would rise and fall with the tides and changing sea levels (Cusick, 2020). Although this can seem a bit far-fetched, the Dutch have been doing this for 400-500 years. As with many things in our society including transportation and mobility, lower income families and the dispossessed are disproportionally impacted (Cusick, 2020).
There are also landscape designs emerging to protect cities and property as flood plains of rivers are shrinking, much of it led by the Netherlands, and have relevance to transportation infrastructure (Mossop, 2021; Rijkswaterstaat, 2019). Research also indicates promise for measuring risks and optimal rerouting of traffic during flash floods, minimizing exposure to motorists (Corns, et al, 2021). A lot can be learned from biomimicry as well (Fairs, 2021).
During the devastating 1993 Mississippi River floods the St. Louis District Engineer stated that “you cannot control Mother Nature.” That was true then and is true now. We can, however, work with Mother Nature, perhaps more as native and indigenous peoples did as they had little choice but to live in harmony.
The climate crisis is an existential threat. Roadway traffic alone accounts for about one-third of greenhouse gas emissions. As such, there are many opportunities for transportation professionals to have a positive impact in reducing and mitigating the climate crisis and associated impacts to our transportation and mobility system (Gates, 2021; Adler, 2021). Some examples (Plummer, 2021):
Rethink transportation grants
Make states measure emissions
Mandate cleaner vehicles (go electric)
Lend a hand to public transit
Push congress for new laws
Still other areas hold promise (Schapker, 2021):
Surface transportation authorization
Highway Trust Fund solvency
Project delivery reforms
Innovative financing
Most recently, Buttigieg and his modal administrators spoke to the AASHT0 Board of Directors on February 25, 2021 and spoke to the pillars that will drive federal transportation policy:
Safety
Equity
Economic Development
Climate Change
Breaking down barriers within the U. S. Department of Transportation, between other federal departments, and with state and local agencies
He and his modal administrators also discussed a variety of initiatives and potential initiatives such as environmental justice, jobs, a partnership with auto manufacturers to alert drivers of on coming trains, user-friendliness/less bureaucracy with smaller communities, a dedicated rail trust fund, increasing bus lanes, sustainable funding, a coordinated government setup on climate change, and others. (Cho, 2021).
These are all critical issues for the transportation and mobility space. These and other critical issues have also been reported elsewhere (see most recent TRB critical issues in transportation report).
Still, our society operates in largely economic terms so we must speak in those terms (Milberg, 2021; Wachs, 2011; Cramer, 2018). One recent example is from Florida, of which the state legislature requires a report on the economic impact of transportation investments (Florida Department of Transportation, 2020). Similarly, the Oregon Transportation Investment Act III first priority required by the state legislature was economic stimulus. That was measured in various methodologies including jobs created or sustained (HDR, n.d.).
Tribal Nations as native Americans have a unique status in our country as dependent sovereignties and they have unique challenges. As such, the USDOT and BIA programs at the federal level are important and must be reviewed for reasons similar to reviewing and updating the funding and allocation that is needed for states and communities, urban and rural, and in a partnering framework. Similarly, this is true for territories as they are American citizens as well.
Eventually, transportation and mobility should be addressed holistically in social, economic, and environmental terms on a routine basis, whether in planning, needs assessments, establishing priorities, or other processes. It is the only way to achieve a sustainable and healthy built-natural environment.
Engaging people is critical to success and all means must be exhausted in the effort, virtual as well as physical. Sometimes the process of making a decision together as a community is more important than the decision made (Couros, 2021). This will require significant outreach, public meetings, education, listening, and a sense of humor yet sober seriousness. The United States and world are filled with good people who want to live good, happy, and safe lives. It is only by engaging and educating people and working together that we will achieve the future we all desire. One recent example by industry was announced December 10, 2020, a coalition of 37 leading company CEOs (www.OneTen.org) has formed One Ten to hire and promote one million Black Americans over the next ten years into family-sustaining jobs with opportunities for advancement. As a meritocracy, we must find ways to yoke the intellectual talent and diversity of all Americans regardless of race, color, creed, sexual orientation or other differences.
There are many, many examples where effectively engaging people has been critical to success, as it is a part of virtually any successful venture. One example, the Nebraska Department of Transportation led a statewide safety summit that over a period of a few years reduced roadway fatalities by 50 percent. More recently, the Kansas City area is engaging people for ideas to reduce roadway fatalities and injuries (Mid-America Regional Council, n.d.).
We have a generational opportunity to transform and improve America’s infrastructure (Buttigieg, 2021), and in a post-pandemic world (Cisneros and Fulton, 2021).
There is much to do and there are many ideas. We need them. Still we need a strategy to guide and align these efforts. Transportation agencies have much in common around the world and state departments of transportation have had a dominant presence in the United States—safety, traffic control, infrastructure planning, project development, design, construction, and maintenance. Because of the rapid move to digital technology, one of the more promising services is cloud technologies or computing and its inherent flexibility, agility, scalability. It offers economies of scale through large, centralized server banks and services that provide hardware, software, and applications through the Internet vice the expense of having them on site. The risks must be weighed, but there appears to be considerable upside, to include improved customer facing outcomes vice “back room” or organizational business processes.
Some of the leaders adopting these technologies include toll agencies who are continually seeking ways to improve customer outcomes which include not only the physical infrastructure and traffic speed but paying tolls as easily as possible. As the move toward a mileage-based system continues, especially given Tesla, VW, etc., and increasing pledges of 100% manufacture-only of electric vehicles by 2035 by Ford, GM, and others, transportation agencies may be operating a lot more like a utility in the near future. As such, the experience of toll agencies may allow them to take the lead. Certainly other transportation agencies can learn a lot as this future evolves. The potential for people and freight to move seamlessly, easily, and without cash, through one multimodal mobility ecosystem is possible, if not highly probable or a virtual certainty. (Wehrmann, 2021).
As the mobility ecosystem continues to change, it is in a unique position to be a substantial help in improving society, the economy, environment, and people’s lives.

There is never enough funding in any organization to meet the needs, much less the wants. The debates to determine funding and how to allocate it are endless and continue to this day at all levels of government (Ryan, 2021). Typically, the effective use of available funding falls to public sector transportation professionals, unless private-sector owners, in conjunction with private sector partners. Thus, it is important to review some analytic tools, methodologies, and aspects for maximizing results with limited funding. These could loosely be considered part of asset management. A more thorough review of asset management, setting a basis, criteria, and priorities, is on the March 6, 2016, article on this website entitled Transportation Asset Management. This discussion merely augments that discussion and is by no means an exhaustive list. In no particular order, these are some of the more important tools, methodologies, and aspects that can help establish priorities and maximize results with limited funding.
Asset Management: Every public and private body is under increasing pressure to justify investment and that it is making the best use of its resources. The essence of asset management is to better prioritize resources to optimize outcomes, basically institutionalizing a business-like approach to managing infrastructure—asset management. The ability to retain, retrieve, and analyze increasing amounts of data in recent decades has enabled evidence-based decision-making on a network scale. Made possible by computers and digital technology, other “big picture” analyses are increasingly emerging to include the discipline of sustainability that facilitates decision-making among economic, social, and environmental realms. Performance metrics also began to evolve at the same time as asset management. The result is a fundamental framework for managing resources or assets:
Performance measures: what target is desired and achievable
Asset:
Inventory
Condition
Utilization
Value in dollars
Life-cycle cost prediction: estimate remaining useful life
Agency or organization cost
User cost
Trade-off analysis and investment strategies (by combining the above to produce an optimized budget)—criteria to develop needs priorities
Develop an emergency fund for unexpected events
Develop program including asset needs priorities with available funding
Asset management is quite literally the best of continuous improvement. That process never ends. More discussion can be found on this website under transportation asset management.
Scope, Schedule, Budget: This is closely related to Planning, design, below. Regardless, as a program or project is contemplated, a preliminary and final scope, schedule, and budget must be developed. Tied to the next bullet point, it is common for scope to creep or an ill-defined scope to create problems later on. As such, that can lead to schedule and budget problems later. This is especially prevalent in mega and giga programs and projects. The takeaway: spend the time necessary up front to conduct thorough due diligence, planning, risk assessment, and scoping. It is a lot better and a lot less expensive in time, money, and resources to do it right the first time vice the second or more times. Effective and efficient program or project controls are essential to track changes against the baseline contract of scope, schedule, and budget.
Planning, Design: There is no substitute for good, solid planning and design. This in no way discounts good construction, maintenance, operations, materials, and other practices. These can all save or optimize dollars when done right. However, many times problems and opportunities missed can be traced back to the beginning of planning and design. It can be a challenge and take time to get input and reviews from construction, maintenance, operations, stakeholders, and partners. It is worth the effort to do things right or as well as possible at the beginning. Otherwise, time and money will be expended later and opportunities will likely be lost. More broadly, open-source engineering can be more valuable economically and in terms of building on standard design specifications. Thus providing more cost-effective projects, more innovation, improved quality, and scalability. (Shepherd-Smith, 2021).
Needs Assessments, Criteria, and Priorities: This may appear obvious, and as stated above it is discussed in more detail in other blogs. Regardless, this process is essential in setting priorities for what to do first, second, third, and so on in spending on the highest priorities. While many governments do this, all do not. The larger, more capable governments tend to do this a lot more than smaller governmental, typically more rural, cities and counties. This typically manifests itself in state departments of transportation doing thorough needs assessments while smaller, less populated cities and counties have neither the staff or funding to do this. This can be a problem. This can be similar in non-highway modes. One solution is to generate one multimodal needs assessment for states, cities, and counties. To gain consensus on such a mechanism would be Herculean but not impossible. As it is, each entity has its own way of identifying needs and setting priorities and the challenge increases as governments establish “formulas” in an attempt to equitably distribute funding to the highest needs. This manifests itself in several ways such as donor and donee states relative to the federal Highway Trust Fund, earmarks depending on the power of elected officials, competitive grants which typically leave out smaller, more rural communities, and others. These are all an attempt to do the best we can but they also fall short. The net result—the inability to fund the highest needs. While it is true that federal and state highways carry the vast majority of traffic, the needs of rural communities are of equal importance. So, the idea of a multimodal and multigovernmental needs assessment should be aspired to if not accomplished. There are some rare examples of similar efforts in other areas that have been successful such as the State of Iowa developing one common state-city-county design manual. Also, the State of Nebraska requires an annual needs assessment (with inventory, standard criteria, inspections, estimated scope and cost, etc) for their state highway system so that the state legislature has a target to determine funding. Uniquely, Nebraska law has a variable fuel tax that adjusts the state fuel tax to meet that funding, regardless of impacts such as decreased fuel consumption due to pandemics or other unforeseen events. A system that effectively prioritizes limited funding to address the needs of one seamless transportation/mobility system would be invaluable to our society vice each governmental entity struggling on its own. While this may never be achieved, it is worth aspiring to.
Design Exceptions, Practical Design, and Least-cost Planning: Until perhaps the last two decades, the standards for planning and design were fairly rigidly followed, partly due to liability risks of not doing so. That is understandable because of the importance of standards. However, as funding continues to be tight as needs grow, exceptions have increasingly been made. This evolution began as design exceptions to established standards, to somewhat broader exceptions termed practical design, and that has evolved into more recently termed least-cost planning. The core purpose of all is to maximize results with limited funding where a high proportion of benefits can be gained while accepting little or no additional risk. These are of course highly scrutinized for approval but can save considerable dollars. One mega program in Oregon had 275 design exceptions which saved $683 million.
Alternative Delivery Methodologies: Alternative delivery methodologies have been around for decades in the form of contracts of which the U. S. Army Corps of Engineers has been one of the more innovative. In 1993 the Design-Build Institute of America (DBIA) agreed upon the term design-build and its use among transportation agencies began to accelerate. Originally established to save time, not money, design-build projects have evolved to save time and money (Figure 8). Other integrated delivery methodologies have also begun to emerge such as design-build-operate, design-build-operate-maintain, construction management-general contractor, public-private-partnerships, and others, each designed for a specific purpose in saving the owner time, money, level of oversight, or all three. The key is that integrated delivery teams can work together, resulting in time and money savings for the owner. Embedded is risk and who has it, but that’s another subject that warrants a paper on its own.
FIGURE 8. Design-build compared to other project delivery methods. Source: DBIA, n.d.
Materials: This may seem out of place but it is not. High-strength steel is a good example of allowing wider gaps to be spanned with fewer vertical supports and girders. Superpave asphalt mixes compete effectively with concrete depending on the costs of oil, cement, and other commodities. Likewise, steel can compete against concrete and accrue savings. Fiberglass reinforced-polymer girders and other corrosion-resistant features have also been employed to extend the design life of bridges to at least 100 years (Knapschaefer, 2021). 3D printed bridges and other structures can save on time and labor (U.S. Bridge, 2021).
Recycling: Recycling is about saving resources and money. Asphalt, concrete, and steel are regularly recycled by owners and construction contractors, through both on-site and off-site processes. Depending on the strength, bridge girders are utilized on other bridges as appropriate. Old rail cars have been recycled as low cost-culverts where appropriate. One of the more innovative recycling methods being studied is to use old wind turbine blades in bridges as well as buildings, etc., rather than placing them in landfills (Stone, 2021).
Engineering Economics: This tool has been around for over 100 years but continues to be relevant although other tools now supplement it and can lead to other conclusions.
Life Cycle Costs: This tool has been around for over 100 years although it has been refined during that time. As our perspectives have increasingly become long-term versus short-term or a human lifetime, the life cycle of infrastructure, vehicles, and other assets have taken on additional meaning relative to least-cost decision-making. Therefore, the life cycle cost of any asset is critical to know.
Return on Investment (ROI): Commonly known as ROI, this is another analytical tool that can have myriad perspectives. That is the ROI in economic terms, jobs created or sustained, environmental values, social values, and so forth. Regardless, knowing the return on dollars expended is a critical part of decision-making.
Benefit-Cost (BC): Benefit-Cost is commonly assessed as a ratio, normally calculated in dollars. Frequently shown as an equation such as a BC ratio of 3:1 or B/C and if the numerator or B is greater than the denominator, then it is concluded to be a benefit. If the numerator or B is less than 1 it is considered a net cost and not a benefit. Nonetheless, this is another important tool in determining investments.
Economies of Scale: This is a methodology that can provide a return on scale. For example, “bundling” projects within a region can reduce mobilization and material delivery costs. Conversely, breaking projects up has the potential to increase competition and reduce costs. While this is not a new concept, it is valuable. The term “bundle” is a relatively new term and is now commonly used. Previously, other terms such as “tied projects” were used to describe the same methodology. Buying materials, equipment, and other assets at scale can also provide economies of scale and reduce costs.
Multimodal Needs Assessments: Typically, needs assessments have been done by asset or mode with critically important and useful outcomes. As mobility has become increasingly multimodal, the question has become how to conduct needs assessments across all modes. Multimodal planning is common but multimodal needs assessments are largely qualitative, not standardized, and not widely accepted. One of the outcomes in the absence of good, repeatable, and reliable multimodal needs assessments is that funding (federal and state) is distributed based on modal assessments, dominated by highways and bridges, and then a somewhat subjective assessment of how to distribute dollars to each mode. Until we achieve a truly standardized multimodal needs assessment with specific criteria, allocating funds to other modes (such as transit and pedestrians) will be a challenge. Generally, transportation is not a particularly partisan topic at governmental levels, partly because it provides objective information to help determine what funds can or will be appropriated and what the long-term implications may be. This is critical for the built environment in which we live.
Operations and Intelligent Transportation Systems (ITS): ITS was one outcome of advancing digital technology. What this allowed was the transportation system to be instrumented with sensors that provide data and information, especially on volume and speed, to a central office that can more quickly and effectively assess and respond to congestion and issues stemming from traffic congestion, crashes, and other incidences. Advanced Traffic Management System (ATMS) is used for traffic management and control and accounts for the most revenue in the overall ITS market. Although the benefit-costs of ITS vary widely from 2-9:1, others exceed 100:1. One ratio used for comparing ITS to more infrastructure is 8:1, a methodology to get more capacity from the existing roadway. The prudent use of ITS technologies can achieve greater benefit at less cost than more concrete, asphalt, and steel. Related, vehicle pricing systems such as electronic toll collection, congestion pricing, vehicle miles traveled, and other road user charging systems can be cost-effective. In addition, transport and supply chain service providers are seeking cost-effective solutions that ITS can provide to boost their productivity, performance, and profits. On e example developed early in Nebraska was a statewide oversize-overweight permitting system that allowed truckers to efficiently route their trucks and cargo and became an effective decision-making tool.
Internet of Things or IoT: There are benefits to be gained throughout society by leveraging IoT, including in government, and new opportunities are continually being uncovered to improve services and efficiencies (Center for Digital Government, 2019; AT&T, n.d.; ServiceNow, n.d.; Descant, 2019).
Partnerships and Collaboration: It is virtually impossible for any organization to have all the talent, tools, and resources to optimize returns for society, the economy, and our environment. As such, partnerships and collaboration are keys to leveraging the unique strengths of an organization. This is not a new concept, but like the exponential growth of our 4th Industrial or Digital Age, the need is greater than ever before. These strategies continue to grow (Salesforce, n.d.).
Program and Project Management: Good program and project management begins and ends with good leadership. The team is all-important since they are the ones that get work done. As such, good leadership can make a team better while bad leadership can destroy a team. This easily translates to improved or decreased performance, costs, and profits. This topic is also discussed in other blogs on leadership, program, and project management on this website. There are many articles and books on program and project management, one of the most prolific and best is Robert Prieto who publishes regularly in PM World. He also authored one of the most comprehensive books on the subject, “Theory of management of large complex projects” (Prieto, 2015). Also, review PMWorld Journal, https://pmworldjournal.com/welcome, and the Project Management Institute (https://www.pmi.org).
Risk Management: This is the identification, evaluation, and prioritization of risks followed by methodologies to minimize, monitor, and control the probability or impact of unfortunate events or to maximize the realization of opportunities. The U. S. transportation industry has enormous risk exposure and among the most risk-prone industries in the world. As such, the federal transportation law—Moving Ahead for Progress in the 21st Century Act, or MAP-21, and signed into law in 2012 (FMCSA, n.d.)—established the requirement for states to develop a risk-based asset management plan. Risk management is a dynamic process and used routinely within the public and private sectors. Without such plans, organizations can be surprised by events with negative financial impact or miss positive opportunities with improved outcomes. The literature on risk management is rich and continues to evolve.
Strong Relationships: This is another topic that might seem odd within a discussion of maximizing results with limited funding. However, the adage “a good relationship can make a bad contract better while a bad relationship can make a good contract worse” reflects the importance of strong relationships. It is common to have disputes but resolving them in a fair and amicable way while preserving the all-important relationships is critical. No one really wins when disputes move to litigation. This topic is further discussed in other blogs on this website, including the importance of trust.
Safety: This may seem an odd topic within the topic of maximizing results with limited funding but the cost in lives, injuries, and property damage is staggering. As has been stated, virtually every transportation organization has the safety of their employees and traveling public as their highest priority. One of these efforts to improve safety, although for NASCAR racing, has important implications for the traveling public (Midwest Roadside Safety Facility, n.d.; Wikipedia, 2021). The work towards a safer built environment will likely never end.
This is by no means meant to be an exhaustive list and is only intended as a sample. The search to reduce costs is part of continuous improvement and that never ends. There are some very simple changes that cumulatively can have huge impacts including the use of LED bulbs in traffic signals and buildings, the use of highly reflective tape rather than electric lit signs, shutting off computers during overnight hours, and so on. This, again, is in no way a substitute for sound and skilled planning, project development, design, construction, maintenance, and operations, all of which continue to evolve and improve within their own discipline.
The Biden Administration recently announced through their Infrastructure for Rebuilding America grants or INFRA some of the above tools and methods as part of their criteria in addition to other related criteria such as climate change, environmental justice, and racial equity (Ichniowski, 2021). Still, other technologies are being advanced with their own inherent efficiencies (New Hampshire Union Leader, 2021; VIA, n.d.; LeBeau, 2021; Danko, 2021; Ewoldsen, 2021). Other technologies that may seem a bit far-fetched continue to advance and may be part of a transportation future and at less cost (Levy, 2021; Subin, 2021; Halvorson, 2021). Still, other areas are advancing, including space, and may well have cost-effective impacts on our futures on earth (Adams, 2021; Hughes, 2020).
