Evaluating the Impacts of RLC Deployment on Intersection Traffic Safety

This study will examine the effectiveness of local red light camera (RLC) deployments in Maryland over the past 10 years on reducing rear-end collisions and right-angle crashes. Based on the findings, the study will then investigate whether RLC deployment has an impact on driver behavior, in particular on their responses to the signal yellow phase. The research team will conduct field observations of individual driver behavior at three sets of intersections, each including one deployed with RLC and its upstream and downstream intersections. RLC deployments in Howard, Montgomery, and Prince George’s counties will be included in this study.
