Abstract: Synthesizing the advantages and disadvantages of social force model (SFM) and cellular automaton model (CAM), a simulation model of mixed traffic flow including pedestrian, motor vehicle and non-motorized vehicle on the interference road section of elementary and middle school’s gate when students going to school was established. The traffic flow characteristics after changing the proportion of students going to school by private car and implementing different traffic organization schemes were analyzed. The results of the examples indicate that its organization phenomena can be realized by decreasing the proportion of pupils taking private cars and implementing different measures of traffic organization optimization according to the different road classes based on self-organization, which enhances the road traffic efficiency and ensures the traffic safety. Meanwhile, the effectiveness and feasibilities of the integrated simulation model are verified. Furthermore these can provide some reference values for the mixed traffic flow simulation of other road interference section.
