摘要:
为研究区分障碍物类型的跨越行为对疏散的影响，基于元胞自动机建立跨越行为模型，采用Dijkstra算法改进障碍物场景下的静态场值，根据跨越障碍物时的难易程度将可跨越障碍物划分为可轻松跨越型（Ⅰ类）和不易跨越型（Ⅱ类），提出体力值的概念，用体力值的大小来区分行人是否具有跨越能力，提出障碍物占有率的概念，通过改变其取值来表示疏散空间中Ⅰ类障碍物数量的不同；分析跨越比例、障碍物占有率、障碍物类型等因素对疏散的影响。研究结果表明：区分障碍物类型的跨越行为更能提高疏散效率，同时也更符合实际；不同跨越比例下跨越障碍物行为对疏散的促进效果不同；障碍物占有率不同时，按障碍物类型跨越行为并不总能使疏散时间降至最低。研究结果可为提高行人疏散效率、制定疏散策略提供参考。
Abstract:
In order to study the influence of crossing behavior distinguishing obstacle types on evacuation,a model of crossing behavior was established based on cellular automata.The Dijkstra algorithm was used to improve the static field value under the obstacle scene,and the obstacles that can be crossed were divided into the easy crossing type (type I) and difficult crossing type (type II) according to the difficulty of crossing obstacles.The concept of physical strength value was proposed,and the size of physical strength value was used to distinguish whether the pedestrian had the ability to cross.The concept of obstacle occupancy rate was proposed,and the change of its value was used to express the difference of the number of type I obstacles in the evacuation space.The influence of factors such as crossing ratio,obstacles occupancy rate,and obstacle type on evacuation was analyzed.The results show that the crossing behavior distinguishing the obstacle types can further improve the evacuation efficiency,and it is more realistic.The obstacle crossing behavior has different promotion effect on evacuation under different crossing ratios.When the obstacle occupancy rate is different,the crossing behavior according to the obstacle type does not always minimize the evacuation time.The research results can provide reference for improving the pedestrian evacuation efficiency and formulating the evacuation strategies.
