本文的目的是通过在元胞自动机空间上应用具有18条行人行为规则的基于智能体的模拟来分析道路交叉路口和立交桥上的行人流动。作为高密度流模拟的一个案例，作者试图用对峙流倒塌假说来追踪几家新闻媒体报道的赤石市浅木里人行天桥事故的发生过程。在低密度情况下，通过将模拟结果与调查数据进行比较，验证了在所设计的规则条件下，行人流具有相似的规律。在高密度情况下，在对峙流假设的假设下，验证了该点触发了实际事故，模拟结果与模拟结果基本吻合。因此，我们的智能体仿真有可能在行人事故分析中获得有洞察力的建议。
The purpose of this paper is to analyze pedestrian flows on road crossing and overpasses through applying agent-based simulation that has pedestrian’s 18 behavioral rules on cellular-automata space. As a case study of high-density flow simulation, the authors try to trace an occurrence process of the accident of Asagiri Pedestrian Overpass, Akashi City, which several news media had reported, by the ‘falling down like ninepins by confrontation flows’ hypothesis. In the low-density case, through comparing between the simulation results and the survey data, we have verified similar patterns of the pedestrian flow under our devised rule conditions. In the high-density case, under an assumption of the confrontation flows hypothesis, we verified that the point triggered the actual accident and the simulation result coincided nearly. Thus, our agent simulation has the potentials to get insightful suggestions on analyses on pedestrians’ accidents.
