Abstract: Based on the definition of pedestrian traffic, the research system of pedestrian traffic was raised followed by introducing specific progress respectively, including modeling and simulation of pedestrian traffic, analysis and reconstruction of pedestrian accident, application study of pedestrian traffic. The following were discussed as main points: (1) the mechanism and applicable conditions of five typical models including benefit cost cellular automata model, magnetic force model, social force model and queuing network model; (2) five key issues of pedestrian accident reconstruction including kinematics and kinetics model, pedestrian injury and protection, uncertainty analysis and automatic optimization, reconstruction method, and computer-based reconstruction technology; (3) the main functions and application situation of five typical pedestrian simulation software including Legion, PedGo, SimWalk, AnyLogic and VISSIM. Finally, the problems and the development tendency of pedestrian traffic were discussed.
