Improvement of Road Project Evaluation Method for Disaster Mitigation and Application to Multiple-Disaster Case in Japan

After the Great East Japan Earthquake of March 2011, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) proposed a new scheme to evaluate the effects of disaster mitigation by road projects. This scheme is composed of mainly two methods: qualitative assessment of disaster resilience and multiplicity between cities (Model 1) and quantitative assessment of travel times in the network (Model 2). The scheme has already been applied to new road construction projects in Japan. However, this method has some theoretical and practical problems as pointed out by researchers and policy-makers. In this paper, the authors improve the evaluation methods and apply them to the Shikoku region which was concerned with huge earthquakes and heavy rain. In particular, the authors combine the two models into the integrated model with theoretical consistency, and consider many variations of frequent disasters such as heavy rain and heavy snow. Results of this research have the potential to contribute towards making it better to understand road project evaluation.
