Abstract: In reality, vehicles and pedestrians are delayed for their interference with each other at the crosswalk, or by the unreasonable allocation of traffic light time. Especially under the popular rule of vehicles yield to pedestrians in front of the crosswalk, traffic flow are seriously affected. In this paper, the effects of pedestrian traffic light and the related parameters on traffic flow are studied. On the road, the Nagel–Schreckenberg (NaSch) model is conducted to simulate the scenario with and without pedestrian traffic light. Results show that, vehicle traffic flow can be effectively improved with pedestrian traffic light. Moreover, the optimization of pedestrian waiting time with different vehicle and pedestrian arrival rates are obtained from comprehensive simulations. Finally, effects of some other parameters are briefly discussed.
