Theoretical system incorporating with mobile observation and simulation for evaluating risks of transport networks in hazardous situation

本研究的目的是建立并验证考虑自然灾害的交通网络可靠性评估的理论体系。在前期科研资助(A)(研究项目编号：17206053)研究成果的基础上，发展了《出行行为数据采集及其分析系统》和《自然灾害下路网可靠性评价理论》。这些系统和理论是通过以下三个部分实现的：(1)考虑灾害情况的行为调查与分析；(2)受灾交通网络的交通仿真；(3)利用交通仿真的可靠性评估模型。经验证，该系统适用于考虑日本可能发生的自然灾害情况下的交通网络可靠性评估。

The purpose of this study is to develop and validate a theoretical system for evaluation of transportation network reliability considering natural disasters. Based on outcomes of our previous research conducted in Grant-in-Aid for Scientific Research (A) (Research Project Number: 17206053), we developed "Data collection and its analysis systems for travel behavior" and "Evaluation theories for reliability of road network in natural disasters". These systems and theories were realized by incorporating the following three parts: (i) Behavioral survey and analysis considering situations in a disaster, (ii) Traffic simulation on transportation network affected by disaster, and (iii) Evaluation model for reliability utilizing traffic simulation. The proposed system was confirmed to be applicable for evaluating transportation network reliability considering possible natural disasters in Japan.
