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.
Connecticut DOT secures deal to limit project delays after years of collaboration
Earlier this month, the US Department of Transportation announced a “first of its kind” agreement between several federal agencies and the Connecticut DOT to speed up review for transportation projects. That agreement took years of relationship building with federal partners and other state agencies to complete, as well as adding specialized skills to the DOT’s staff over time.
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.
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.
Tight corners save lives
Since early in the highway era, road designers have tended to favor wide, rounded corners, and dedicated slip lanes that let drivers turn through an intersection without having to slow down quite as much. As many engineers and transportation advocates know, however, those wide turning radii can create issues for people trying to cross on foot. They create longer crossing distances, exposing people to traffic longer, and they increase the chance of a pedestrian crash by 50 percent or more, according to one new study.
Cities look toward design in achieving Vision Zero
Looking to improve safety and eliminate traffic fatalities, at least 17 American cities have committed to Vision Zero. In addition to ramping up education and enforcement, these efforts require road designers to rethink streets and intersections in ways that minimize risks to non-motorized users. This often means correcting issues resulting from a strict, decades-long focus on vehicle movement.
Partnering improved highway design and behavior interventions for increased safety
After a spike in traffic deaths in the first half of 2015, USDOT and NHTSA have offered a response that fast tracks the development of safety technologies and strives to improve driver behaviors. However, it is silent on roadway design.
