Different types of intersection were simulated with different traffic control variants. Simulation results of a wide range of types of intersection and traffic signal phases showed that an additional protected green phase for traffic turning left generally resulted in no relevant restrictions to the capacity of the intersection. In the case of large intersections with a high volume of traffic, a protected signal for traffic turning left increases safety for traffic turning left and oncoming vehicles. In the case of large intersections with a medium volume of traffic and small intersections with a high volume of traffic, “protected” systems for traffic turning left are the most efficient solution both in terms of traffic flow and road safety. Standardizing these types of regulation at traffic light‐controlled intersections helps to reduce conflicts between turning left vehicles and pedestrians and cyclists too.
