Our infrastructure isn’t prepared for climate change. This summer’s record heat wave has illustrated the immediate impacts of extreme weather and temperature events on our safety and ability to travel. As climate change accelerates these extremes, we need to be prepared to enhance our infrastructure’s resilience and adaptability.
While electric vehicles continue to become more mainstream, we might be headed toward a peak. Electric vehicles remain a key focus for reducing emissions, despite barriers such as grid capacity, consumer preferences, and mining for materials. But as the push for large-scale electric vehicles accelerates, new barriers and opportunities emerge.
The interstate highway system is arguably the largest and most impactful project in American history—not just in terms of its cost and the way it connected businesses and cities across the country, but also because of the devastating impact it had on people of color and low-income communities in central cities. All levels of government played a role in pushing interstates through cities. Now it is everyone’s responsibility to confront the long-term consequences. The federal Reconnecting Communities program marks an important turning point in addressing these impacts, but also represents the beginning of a decades-long process to address and correct past damages.
Many areas of the country are not well served by public transportation, resulting in households without access to a personal vehicle being significantly disadvantaged. In such areas, travelers may rely on a combination of ride-hailing services, informal car-sharing and ride-sharing, and even medical transport, or they forgo trips altogether. A lack of transportation options can keep people from getting to work, accessing essential services, and make gathering necessities difficult.
The Biden administration’s newly released National Blueprint for Transportation Decarbonization represents an historic mission alignment among federal agencies to meet an economy-wide goal of net-zero greenhouse gas emissions (GHG) by 2050. The U.S. Departments of Energy, Transportation, Housing and Urban Development, along with the Environmental Protection Agency, have developed this joint strategy to guide the decarbonization of the transportation sector—the largest GHG contributor, currently generating roughly one-third of U.S. emissions.
The impacts of telecommuting often come up in SSTI’s work around travel demand management and climate action plans, so our team makes a point of staying on top of the latest relevant research. Although the pandemic showed us that remote work helped cut traffic considerably, especially in major job centers, the verdict is still out on whether widespread telecommuting could really help lower travel demand. A growing number of studies suggest it could have the opposite effect.
More and more people are recognizing the costs associated with driving, and that driving less opens space for alternatives and makes us healthier. Now new research adds one more tick to the human health costs column: particulates from transportation cause cancer.
Safety is a top priority for every state DOT, and in many parts of the country that effort extends to wildlife, as many species are changing their migration patterns to adapt to climate change.
The adoption of electric vehicles is growing in the United States, with all-electric vehicle sales increasing by 85% from 2020 to 2021 and plug-in hybrid sales rising 138%. This is a welcome trend for many, but the increased popularity of EVs combined with better fuel efficiency, and a gas tax that hasn’t been raised in thirty years, is posing a major challenge to policy makers; how to make up for lost gas tax revenue, which currently pays for 29% of state highway funds and 84% at the federal level.
Induced demand. It’s a concept that used to be popular only among the wonkiest transportation experts, and now gets covered by outlets ranging from the Washington Post to the Wall Street Journal. Governing calls it “the almost universally accepted concept” that almost no one understands, while Strong Towns calls ignorance of the concept “professional malpractice.” With new tools and a better understanding emerging, some transportation agencies are now beginning to wrestle with the implications.
