摘要：AbstractAnalyzing pedestrian flow characteristics and the interaction mechanism among pedestrians or between pedestrians and environment, we proposed a pedestrian flow simulation model based on the multi-agent technology. In the model, the hierarchical structure of multi agents was designed according to communication relations, and inner structures including network agent, grid agents, pedestrian agents and service interface. Furthermore, a superimposed shortest path algorithm was proposed to cater for the modelling of complex topological network with multiple exits and inner barriers. Pedestrian decision-making rules were established synthetically by considering the distance factor and pedestrian herd mentality factors. A scenario was studied in which pedestrians tried to evacuate from a large room with inner barriers and four exits. The results show that the weight factor of the network edge impacts the crowds shape at exits. In addition, simulation experiments show the trend of evacuation times with respect to the impact factor of pedestrian herd mentality.
