项目摘要

In this study, we developed the traffic model who expressed a route choice of a driver with a multi-agent simulation system. We adapted ourselves in the model that we developed the model that evaluated reliability for running time of a car and developed for a virtual model network and a real road network for a road network when a big earthquake occurred, we developed the system which predicted outbreak of a simultaneous frequent occurrence fire and the situation of spread of a fire. In addition, we evaluated access characteristics of an emergency vehicle at the time of an earthquake disaster, and having considered the allocation of cars of an urgent vehicle (a firefighting pump car, an ambulance) of each fire department place by reliability analysis of a road network.We developed the system which predicted the area where an access characteristic of an urgent vehicle for a road network of normal time (in normal) was low by using the reliability analysis system. And we predicted how a road network was damaged at the time of an earthquake disaster and developed the model in order to built a road network. But, about the prediction model of a refuge traffic action, we built a system with a multi-agent of adaptation model. We developed the model that predicted how it occurred and how spread with time where a simultaneous frequent occurrence fire at the time of an earthquake occurred.We get possible to calculate the area where a firefighting vehicle must arrive at early by utilizing an above system. We developed a traffic micro-simulation system with Petri-net simulator to run a general vehicle and a first aid vehicle at the time of an earthquake disaster. We analyzed the most suitable course instruction that utilized ITS technology and an effect of the most suitable signal control for normal time and after big earthquake outbreak.

在本研究中，我们开发了交通模型，通过多智能体模拟系统表达驾驶员的路线选择。我们在模型中进行了调整，我们开发了评估汽车运行时间可靠性的模型，并为发生大地震时的道路网络开发了虚拟模型网络和真实道路网络，我们开发了预测爆发的系统同时频繁发生火灾且火势蔓延的情况。此外，我们评估了地震灾害时紧急车辆的通行特性，并通过道路的可靠性分析考虑了各消防局场所的紧急车辆（消防泵车、救护车）的车辆分配我们开发了通过使用可靠性分析系统来预测紧急车辆对于正常时间（正常）路网的访问特性较低的区域的系统。我们预测了地震灾害时道路网的受损情况，并开发了模型来建设道路网。但是，对于避难交通行为的预测模型，我们构建了一个具有多智能体适应模型的系统。我们开发了一个模型，可以预测地震发生时同时发生的多发火灾的发生方式以及随时间的蔓延情况。通过利用上述系统，我们可以计算出消防车必须提前到达的区域。我们开发了一个带有Petri-net模拟器的交通微观模拟系统，用于在地震灾害时运行普通车辆和急救车辆。我们分析了利用ITS技术的最合适的课程指导以及平时和大地震发生后最合适的信号控制的效果。
