When gas prices spike, millions of Americans have little choice but to pay the bill. That is not just a cost problem. It is a sign that the U.S. transportation system rests on a fragile foundation shaped by land use and infrastructure that require a car for most everyday trips. At the same time, the transition to electric vehicles remains slow and uneven.

Roads less traveled: the safety surprises of big cities
The most effective way to stay safe on city streets is remarkably simple: drive less. A new report from StreetLight Data suggests that the vehicle miles traveled (VMT) is the single most important factor in determining how safe a city’s streets are for everyone. Risk is not solely caused by bad drivers; daily driving habits and city layouts play a significant role as well. With U.S. crashes resulting in 2.4 million injuries or deaths in 2023, one of the best safety strategies for planners and engineers is to help people spend less time behind the wheel of a car by making walking, biking, and transit easier to use.
A transportation system that works for grandma benefits everyone
Designing for “all ages and abilities,” – meaning accessible curb ramps, bus stops, and safe bike paths – is not new to most transportation professionals. But meeting the needs of aging Baby Boomers will take a more systemic approach to building for all ages and abilities. Living in places with more developed and reliable transit and sidewalk networks where goods and services are close by is good for seniors, and for everyone else.
Addressing the rise in drunk driving requires a systemic approach
Human behavior is one of the biggest wildcards in preventing traffic deaths and serious injuries. That is why many transportation professionals now focus on designing systems that stay safe even when people inevitably make mistakes. Alcohol impaired driving is once again on the rise in the United States, and decades of awareness, education, and enforcement have not solved this problem. New research shows that alcohol is involved in nearly one-third of all traffic deaths, even as public concern about the issue remains very high. In other words, people know drunk driving is dangerous, but some do it anyway. This is not about excusing impaired driving but about acknowledging reality and designing transportation systems that reduce harm when risky behavior persists.
One year into congestion pricing, every DOT can learn from New York City
New York City shares many of the same goals as state and local transportation agencies: cutting traffic, improving travel times, making roads safer, and improving quality of life. Yet decades of investment in highway capacity have failed to deliver on those goals. Commute times have increased 7.5% since 2010, congestion has reached an all-time high, and U.S. roadways have become more dangerous than those of any other wealthy nation.
New research shows where low stress streets make the biggest difference
Making streets less stressful for walkers and bikers is strongly associated with more walking and biking, and new research from Maryland helps clarify where those effects are most pronounced. Building on prior research showing that lower-stress street environments are linked to more walking and biking, this study found that reducing traffic stress has the biggest impact for shorter trips and in places where alternatives to driving already exist. for shorter trips and in places where alternatives to driving already exist.
More transit means safer streets
To reduce traffic deaths, public transit should be seen as a core part of safety infrastructure, not just an alternative mode of travel. Every day, thousands of car crashes occur in the U.S., resulting in injury or death, yet they receive far less attention than the much rarer crashes involving public transit. For city planners working to reduce roadway fatalities, understanding how these perceptions influence travel choices is critical.
Driving trips are dropping, especially among young people
For years, people wondered whether travel would bounce back after the pandemic. The latest FHWA data, along with other new research, gives a clearer answer. Growth has slowed. In 2024, total vehicle miles traveled (VMT) finally inched past its 2019 peak, but by only 0.5%. On a per capita basis, Americans are still driving less, down 2.3% since 2019.
Emotional perceptions can be a tool for predicting street safety
How a street feels can matter just as much as how it’s physically built. A new study shows that emotional perceptions about whether a street seems inviting, secure, or rundown can help explain safety for people walking or biking—a reminder that planners should think beyond conventional design standards. Road designers should also consider the character and aesthetics of the spaces they create.
For better mental health, researchers recommend walking and biking
Staying grounded and mentally fit can be challenging these days. While some people turn to meditation or self-medication, a large and growing body of research points to a simpler solution: walkable neighborhoods and bike-friendly streets. Not only can they improve physical health, but they also offer meaningful benefits to our social and emotional well-being. As we’ve noted, extended periods driving can have the opposite effect.
