场论模型下的多方向行人仿真

Multi-direction Pedestrian Simulation Based on Field Theory Model

常用的元胞自动机模型的研究重点是对向行人流,当行人方向增加到3向甚至更高时,元胞模型将会非常的复杂导致难以大规模仿真。基于场论的行人流模型可以较好克服元胞模型的不足,通过场论模型仿真行人多方向的运动实现真实行人的运动状态。基本图结果表明,多方向行人仿真基本图显示在行人密度较高的情况下可以得到更高的速度,在低密度下则相反。

The current study focuses on bi-directional pedestrian flow based on cellular automaton model. When the direction of pedestrians is increased to three or even higher, the cellular automaton model will become very complex and difficult to simulate in large scale. Pedestrian model based on field theory can overcome the shortage of cellular model; the simulation result of field theory model with multi-direction can achieve real pedestrian motion. Fundamental diagram of multi-direction pe-destrian simulation shows that the higher speed can be obtained at higher pedestrian density, and the opposite results in low density.
