Abstract
The objective of this study is to investigate travelers' adjustment to natural disasters. Japan's 2015 Kanto-Tohoku heavy-rainfall disaster caused severe network disruption. However, due to quick recovery by road administrators, most of the network-closure points recovered within a week. In addition, the authorities started providing specific information concerning traffic congestion to travelers via road signs. Data related to changes in the travelers' access traffic information and plan their travel were collected over two periods: (1) immediately after the disaster and (2) in the longer term. It was observed that the number of respondents who accessed specific information and departed as usual increased with the progress in disaster recovery. In addition, the results revealed that respondents' socio-demographic features and travel behavior in the immediate aftermath of the disaster were significantly correlated with their changes in accessing information and making decisions to plan their travel in the later period.
