主 题：bottleneck pedestrian crowd simulation exit location bottleneck length obstacles location
摘 要：Pedestrian flow through narrow exits is one the most important features of crowd dynamics and *** is a particularly important aspect of pedestrian simulation models in that the accuracy is highly dependent on their ability to produce realistic exit flow *** firstly identified the four parameters that are most critical for physical interactions of the social force model and then calibrated them against two well-controlled pedestrian *** these calibrated parameters,we discussed the reasonable settings of sensitive parameters for different levels of pedestrian ***,we revisited the basic questions about the effect of the exit location,the bottleneck length,and the effect of obstacles on pedestrian *** simulation results indicated that:(1)The effect of the exit location on the pedestrian egress efficiency is uncertain,and the evacuation efficiency is also related to the exit width and the level of urgency.(2)Thepass-wayafter the exit also named as the bottleneck length has a negative impact on the evacuation performance only in the scenarios that the bottleneck length is not more than 2.0 *** the bottleneck length exceeds 2.0 meters,pedestrian outflow efficiency reaches an asymptotic.(3)Setting an obstacle near an exit is not leading to a longer pedestrian evacuation time,instead,it is effectively improving pedestrian evacuation.
