Turn-on-Red Prohibitions for Dual Right-Turn Lanes

The project will examine right turn on red at signalized intersections where there are two right-turn lanes. Researchers will study the impacts of different right-turn-on-red configurations at various locations on safety performance and traffic level of service by analyzing crash and traffic data as well as observing travel behaviors at selected intersections. The researchers will develop recommendations for right-turn-on-red policies, helping transportation agencies to improve traffic safety and travel efficiency as well as ensure consistent practices across Illinois Department of Transportation districts.
