This study evaluated the safety effect of the flashing yellow arrow (FYA) treatment at signalized intersections. The major objective of this strategy is to reduce the frequency of left-turn (LT) crashes, especially those that involve a collision between left turns and vehicles traveling straight through from the opposite direction. The project team

Speeding contributes to over a quarter of all road trauma and is a persistent driving behavior that brings harm both to the vehicle occupants as well as other more vulnerable road users. In 2018, speeding related crashes resulted in 9,378 deaths which is a staggering 26 percent of all crash fatalities. Agencies who want to address speeding are ofte
