In order to increase the safety of pedestrians crossing roads with heavy vehicular traffic, signalized pedestrian crossings are increasingly being used. However, traffic signals cause disruptions in traffic flow and time losses for vehicles resulting from stops during the red signal phase. This paper presents a model and simulation program that was used to analyze the efficiency of various control strategies at a signalized pedestrian crossing, i.e., fixed-time signaling, actuated signaling, and cascaded actuated signaling. The presented research results show that advanced control systems can improve vehicle traffic flow and reduce time losses for both vehicles and pedestrians.Increasing traffic volumes make the use of non-signalized pedestrian crossings increasingly unsafe. This is particularly true for crossings located on dual carriageways in suburban areas, characterized by high traffic volumes and high driving speeds. Regulations [1] recommend the use of full or actuated traffic signals in such cases. (…)
