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.

We don’t need to overthink induced demand to act on it
The concept of induced demand is now widely recognized in transportation. But we often treat it as a technical modeling issue rather than a basic principle of how people respond to the world around them. Build for cars, and you’ll get more driving; build for transit or biking, and you’ll get more of those too. Shifting the conversation in that direction can improve near-term decisions and strengthen communication between transportation professionals and the public.
To reduce traffic, DOTs need both “carrots” and “sticks”
Nearly every state DOT is grappling with how to reduce traffic and carbon emissions—many states developed official , and congestion relief is often at the top of a DOT’s priority list. But a new study from Swedish researchers says that some of the most common ways to address these challenges—using only “carrots” rather than “sticks,” in the researchers’ words—may leave states struggling to achieve their goals.
Caltrans review finds outdated and misunderstood models hinder project analysis
In California, where travel demand models often guide project-level decisions and analysis, a new report finds many are outdated, poorly documented, and ill-suited to the purposes agencies sometimes use them for. Transportation agencies rely on models to forecast traffic and guide billions of dollars in infrastructure investment. Without updates, these tools risk locking in old assumptions about growth and travel behavior rather than helping agencies plan for a more sustainable and efficient future.
Repairing highways is better for the economy than expanding them
The U.S. faces a $1 trillion backlog of roads and bridges needing repair, according to FHWA. Yet we still spend roughly $27 billion per year (25% of the total) expanding and building new highways. Mounting evidence shows that shifting those dollars toward maintenance and rehabilitation could yield greater benefits.
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.
State action spurs local parking reform
Earlier this month, Denver, Colorado eliminated minimum parking requirements from its zoning code for all developments across the city. We’ve promoted the benefits of reforming outdated parking policies, including lower construction costs and better traffic management. In Denver and many other cities, changes at the state level helped catalyze the city’s reforms.
California will let agencies pay for housing to offset increased driving
A new California law gives transportation agencies the option to pay into an affordable housing fund to offset the increased travel demand associated with major road projects. The approach could achieve several goals at once: mitigating emissions from highway expansions, creating a new funding stream for affordable housing, and helping more people live in accessible neighborhoods, reducing their transportation costs.
Washington State’s new shared streets law could set an example for pedestrian-friendly design nationwide
Washington recently became the first state in the country to authorize “shared streets,” a shift that could reshape how people move in cities across the state and serve as a model nationwide. The measure gives walkers and bikers priority, slows vehicle traffic to 10 miles per hour, and removes jaywalking restrictions. Washington’s law, signed in April, is a major step toward safer, people-centered streets.
Low-stress roads and bike lanes improve safety, not just comfort
Low stress roads make biking more comfortable, especially for people who are more risk-averse. But do they make biking safer? A new study suggests they do, countering concerns from some transportation officials that these facilities might encourage unsafe riding.
