Abstract
At the time of the Great East Japan Earthquake in 2011, a lot of the evacuees who used vehicles fell victim to the tsunami because of the heavily traffic congestion. Not only in this example, traffic congestion at a large-scale earthquake often has negative influences in various cases, for example occurrence of traffic accidents and obstruction of emergency vehicles. Therefore, it is urgently necessary to work out a plan which can make an evacuation by vehicles quick and reliable. Accordingly, this study aims to represent the traffic situation when an earthquake occurs by developing the evacuation simulator considering the analysis of vehicular behavior in the last Great East Japan Earthquake. Furthermore, a case study is conducted to assess the effects of the evacuation plans considering both structural and non-structural measures for easing traffic congestion.
