摘要：

为了研究路径选择行为对行人消散的影响，基于社会力模型，建立行人路径选择模型.从决策层和策略层两方面对行人路径选择行为进行建模，利用离散网格代表行人所有可能期望速度方向，建立每个离散网格的权重决策模型.通过对10×10房间内行人疏散进行仿真，得到行人消散时间随行人数目的变化规律.对比分析改进模型、实际数据和其他模型的数据，结果表明，行人路径选择行为能够有效提高行人的消散效率，加入路径选择模型后，改进模型得到了更加符合实际数据的速度-密度关系图.改进模型在行人密度大于1.4人/米2条件下具有更重要的意义.
Abstract:

A pedestrian route choice model was proposed based on social force model, in order to analyze the effect of route choice model on the pedestrian evacuation. The route choice models were established from decision-making level and strategy level. A discretization grid was used to represent all the potential moving directions of pedestrians, and the weight of every potential moving direction was modeled. The simulations were conducted in a room which is 10 by 10 meters, and the relationship between evacuation time and pedestrian number was acquired. The simulation results were compared with the observation data and other models. Results indicate that route choice model can improve pedestrian evacuation efficiency. The relationship between speed and density accorded with actual data closely by integrating the route choice model into social force model. The modified route choice model is more effective when the pedestrian density is larger than 1.4 pedestrians/m2.
