摘要：AbstractThe different conflicts between pedestrian and vehicle induce traffic delay and decrease urban the efficiency of road traffic at a certain extent. Rare researchers pay their attentions to the pedestrian and vehicle conflict system as whole. Based on characteristics and conflict scenes analysis of pedestrian and vehicle behaviors at isolated signalizedized intersection, 4 types of ped & veh behavior rules are described, the ped-veh inference courses by once and twice pedestrian crossing are expatiated, then, 3 delay models of ped-veh system are established. Finally, taken advantage of VISSIM software and big intersection in Beijing as example, a simulation case is calculated. Data shows that: due to twice pedestrian crossing, the system delays are 14.3% and 7.4% less than once one at a.m. and p.m. peak time separately.
