Intersection safety is a research area that focuses on reducing the number of accidents and collisions that occur at intersections, which are common hotspots for traffic accidents. Researchers in this area study various factors that contribute to intersection hazards, such as driver behavior, road design, traffic control devices, and vehicle technology. The goal of intersection safety research is to develop effective strategies and interventions to improve safety at intersections and reduce the number of injuries and fatalities that result from intersection crashes. This may include implementing traffic signal timing changes, adding roundabouts, improving visibility, and enhancing driver education and awareness.
