How teens can be safer drivers
Motor vehicle crashes are the leading cause of death for teenagers in the U.S. Will raising the requirements for a driver’s license help?
4th traffic light would benefit pedestrians and drivers
Adding a white phase to stoplights that communicate with autonomous vehicles would decrease delays at intersections by 25%, researchers say, even when pedestrians are added to the model.
Traffic deaths decline slightly, but remain higher than before the pandemic
Safety experts have struggled to pinpoint why traffic and pedestrian fatalities have remained so stubbornly high.
Why cities should consider roundabouts
COMMENTARY | An alternative to traditional signalized intersections, roundabouts can substantially offset the dangers posed by larger vehicles, ensuring that any potential impact is less severe due to moderated speeds and oblique angles of collision.
County’s advanced mapping tool supports development decisions
Henry County, Georgia, used it to decide where freight facilities should go. But the computer-based tool could be repurposed to help other communities address their hot-button issues.
Traffic tickets can be profitable, and fairness isn’t the bottom line in city courts where judges impose the fines
COMMENTARY | Research shows police officers issue more traffic tickets and judges impose more fines when their city gets the money and when the budget is tight. But if states change the rules about who keeps the money, the incentives for revenue maximization go away.

Cities paint the way to safer streets
COMMENTARY | It’s time for our country to embrace asphalt art as a creative, low-cost way to improve safety for pedestrians and cyclists.
