Design of Pedestrian Twice Crossing Street and Impact to Pedestrian Delay

Pedestrian is an important part of the mixed traffic flow.How to solve the interference between the pedestrian flow and the vehicle flow is the important element to improve the status of China's urban transport.In this paper,the pedestrian twice crossing the street program and its research on pedestrian delay are intended to solve the intersection of pedestrian and vehicle traffic interference and conflict.The dissertation comprehensive analyses pedestrian crossing facilities.Summed up the conditions and design the standards to set the pedestrian twice crossing the street settings,analyse the change of different signals and the pedestrian delay model.Simulate the different cases of Sitongqiao intersection.The pedestrian twice crossing the street can improve the safety of pedestrians,save the waiting time,increase the efficiency of pedestrians,reduce the rate of illegal pedestrians cross the street and reduce interference between vehicles.
