Human Behavior Model in Consideration of Detailed Personal Attributes in the Aftermath of a Devastating Earthquake

基于城市人口出行调查数据，估算了城市人口的时空分布，并进行了假设发生破坏性地震的各种模拟分析。首先，构建了描述财产损失的环境信息模拟器和描述人类行为的人类行为模拟器，并利用这两个模拟器对广域疏散阶段进行了分析。其次，构建了描述和可视化大型火车站附近行人流动轨迹的行人流模型；在此基础上，构建了通勤行为模型，该模型描述了震后公共交通瘫痪情况下上班族上下班的意愿和能力。利用该模型，对职工上下班的可能性和概率进行了分析。

The spatiotemporal distribution of persons in the metropolitan area was estimated based on the data of a metropolis person trip survey, and the various simulation analyses assuming the occurrence of a devastating earthquake were performed. First, the Environment Information Simulator which describes property damage, and the Human Action Simulator which describes human behavior were constructed, and the phase of wide-area evacuation was analyzed by use of these simulators. Next, the Pedestrian Flow Model which describes and visualizes people's move locus in the vicinity of a large scale railroad station was constructed. Furthermore, the Commuting Action Model was constructed, which describes the workers' intention and capability of commuting to offices under the situation where the public transportations are paralyzed in the aftermath of a large earthquake. By using the model, the possibility and probability of workers' commuting to offices were analyzed.
