Abstract: The running of vehicle is influenced by the vehicles of the driveway and the front or the later vehicles of the adjacent lanes. In city traffic, the impact of mixing motor vehicles and non-motor vehicles on the running of vehicle is particularly complex. Through the research on the essential characteristics of mixed traffic flow, considering the “friction” and “blocking” interference of non-motor vehicle on the motor vehicles in lane changing rules and the acceleration and deceleration rules. The cellular automata (CA) model describing the mixed traffic is proposed, and numerical simulatings show the basic law of mixed traffic flow fundamental diagram when the non-motor vehicles and motor vehicles blended in different ratio.
