摘　　要：Simulation of pedestrians’behavior in the hub can help decision-makers to formulate better evacuation strategies.With this aim,this study develops an improved cellular automata model considering pedestrian’s mass-following psychology and competitive awareness,and based on this model,pedestrian’s evacuation process from the channel of the hub with two exits is simulated.Moreover,dynamic guidance information,e.g.,the realtime congestion situation of the evacuation routes,plays an important role during pedestrian evacuation processes in a hub,as the evaluation routes can be adjusted based on this information.That is,the congestion situation during the evaluation can be improved.Thus,dynamic signs are incorporated into the proposed model to study the influence of dynamic guidance information on pedestrian evacuation behavior.In simulation experiments,the influence of two parameters,namely the proportion of pedestrians unfamiliar with the hub and update interval of dynamic signs,on pedestrian evacuation behavior is studied.Results show that dynamic guidance information can improve the efficiency of pedestrian evacuation.In particular,the higher the proportion of pedestrians unfamiliar with the hub is,the more obvious the effect of dynamic guidance information is.Besides,different proportions of pedestrians unfamiliar with the hub lead to different update intervals of dynamic signs.Finally,the results of this study can provide some implications to the practical hub operation and evacuation,e.g.,to standardize the order of evacuation routes and improve the information service level in the hub.
