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.

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 states are moving away from the 85th percentile rule to set speeds
States are increasingly moving past the outdated “85th percentile rule” for setting speed limits, weighing factors other than the observed traffic flow in those calculations. The AP recently highlighted Ohio among a wave of efforts to consider roadway context and the presence of walkers and bikers in allowing lower speeds to ensure safer roads. For states looking to follow suit, a newly released report from the Center for Pedestrian and Bicyclist Safety offers states a data-driven, objective framework to set speed limits based on roadway context, not just vehicle movement.
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.
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.
Complex urban streets encourage safer driving
Reducing excessive speeding is one of the most effective ways to improve road safety—especially where people are walking or biking. While lowering speed limits and adding traffic calming measures help, growing research highlights the value of self-explaining streets that give drivers constant cues to slow down.
Pedestrian deaths aren’t accidents, they’re policy failures
Pedestrian deaths are rising faster in the U.S. than in any other high-income country. A decade-long surge, up 50%, has made the U.S. the most dangerous place to walk among 27 peer nations. Many experts view these deaths not as random accidents but as preventable tragedies that reflect deeper policy failures in transportation, infrastructure, and public safety.
Involving walkers and bikers in design can make streets safer
Including road users in a participatory “co-design” process can result in better safety interventions than those made by professional engineers alone, according to a new study. Participatory design incorporates the needs and views of end-users of what’s being designed—in this case, pedestrian crossings used by workers and students.
Want to respond to crashes quicker? AI could help
State transportation agencies are cautiously dipping their toes into the waters of “artificial intelligence” and “machine learning” to find applications in the transportation field. There are many potential uses, according to a new report, including opportunities to track assets like crosswalks, and to clear traffic incidents faster, which could lessen the need for major capacity investments. Agencies have also identified some lessons and pitfalls of the technology as they pilot new tools.
