英文摘要： In accordance with the universal law of large scale pedestrian mustering and evacuation under complex traffic system, this project tries to collecting data from transportation terminals, sport stadium, large malls. Individual pedestrian state, and temporal space behavior and traffic flow characteristics will be analyzed. It will study microscopic pedestrian behavior and their interactions. Pedestrian flow motion anisotropy, non- equilibrium, non-stable, nonlinear dynamics characteristics and self organization, bottleneck oscillation and transformation phenomena will also be discussed. Furthermore, it will study the large scale pedestrian generation, motion, mustering, crowd, evolution and evacuation rules using system analysis and typical scene experiment method, it will study the interactions between pedestrian flow and various facilities. It would propose the critical condition of pedestrian safety evacuation in complex traffic systems. It would build a crowd dynamic model, study simulation algorithms under large scale conditions. By research, it could reveal basic characteristics and rules at large scale pedestrian crowd in complex traffic systems. It could give a general description of pedestrian facility interactions, it would propose the operation, control and management strategy, develop an experimental simulation system and comprehensive assessment system for pedestrian crowd in complex traffic systems.
