Banning Left Turns at Intersections Could Improve Safety and Traffic Flow

Research led by Dr. Vikash V. Gayah from Penn State University highlights the dangers of left turns at intersections. With over 60% of intersection collisions involving left turns, cities like San Francisco and Salt Lake City are implementing restrictions. Left turns pose risks such as angle crashes and pedestrian accidents. Additionally, left turns contribute to inefficiencies in traffic flow, causing delays and increased fuel consumption. By restricting left turns during peak hours and considering alternatives like roundabouts, cities can enhance safety and traffic efficiency. While banning left turns may slightly increase travel distances, it ultimately leads to quicker commutes and improved fuel efficiency. (Studyfinds)
