地铁车辆安全疏散性能的仿真研究

从正在运行的北京地铁某型号车辆的空间布局特点出发,在现有的元胞自动机模型和行人流模型基础上,运用人员动态调整自身速度、动态调整自身运动方向等技术,建立了一种基于车辆环境约束以及人员行为特性的元胞自动机模型,该模型具有人员速度可变、能复现人员自组织现象的特点。论文以北京地铁某型号车辆为仿真对象,对车辆不同布局对车辆人员安全疏散性能的影响进行了计算机仿真并加以分析,提出改进建议。

Simulation and analysis of passengers' evacuation ability in subway under urgent conditions

Through analysis of a kind of subway vehicle's space feature and using of the technique that passengers adjust their speed and move direction dynamically,a cellular automata model was built which took the restriction of vehicle and dynamical feature of pedestrians into account on the base of cellular automata models and pedestrian flow models.This model has features of the dynamical speed for people on the basis of pedestrian density and using self-organization phenomena to modify pedestrians' behaviors.A kind of subway vehicle was studied and the effect of different vehicle space distribution on the safety of passengers' evacuation was simulated with the improvement advice for vehicle.
