基于社会力和导航场的轨道交通人群仿真
Crowd simulation based on social force and navigation field for rail transit

摘要 针对轨道交通内人群运动的特点，在传统社会力模型上引入导航场构建人群仿真系统.其中，社会力模型负责行人与周围行人及环境的相互作用，而导航场负责行人在轨道交通站点中的路径规划.与传统社会力模型相比，可避免因设置中间目标点不合理导致的“抖动”及局部拥堵现象.在上述基础上，研发一个面向轨道交通的人群仿真系统，并以北京市动物园地铁站作为场景进行实验.结果表明：仿真过程中，人群没有出现“抖动”或局部拥堵现象，这种方法适用于轨道交通中的人群仿真.
Abstract：In view of the characteristics of crowd movement in rail transit, a navigation field is introduced on the traditional social force model to build a crowd simulation system, in which the social force model is responsible for the interaction of pedestrian with pedestrians and the environment around them, while the navigation field is responsible for the pedestrian's path planning in the rail transit.Compared with the traditional social force model, it is possible to avoid the “jitter” or the local congestion caused by the unreasonable setting of the intermediate target point. Based on the above,a crowd simulationsystem is developed for rail transit and the Beijing Zoo Subway Station is used as experimental scenario. The experimental results show that there is no “jitter” or partial congestion during the simulation. This method is suitable for crowd simulation in rail transit.
