Based on the different characteristics of stochastic and congestion dispersing processes for pedestrian flows, two kinds of right-turning vehicle';s delay models were defined by using stochastic distribution theory, and the delay characteristics during vehicle crossing pedestrian flow were analyzed. The crossing process of right-turning vehicle was simulated by using Vissim software, and the simulation delay value was compared with that of the delay models. Analysis result shows that when the length of pedestrian congestion dispersing time is 10 s, the length of pedestrian stochastic dispersing time is 15 s, each interval between pedestrians is 5 s, and pedestrian flow reaches 1100 persons per hour, the deviation of the delay models is only 0.2 s, so the models are feasible.
