Title:

The Impacts of Information Provision on Post-Disaster Traffic State

Accession Number:

Record Type:

Component

Abstract:

This study investigates the impacts of information acquisition through a social network on evacuation performance during disasters. Information propagation among evacuees through a social network is first modeled time-dependently based on evidence observed in the aftermath of the Great East Japan Earthquake in 2011. The model is designed so that communications not only through social media, e.g., via smartphones, but also face-to-face and from public broadcasts can be described. Evacuation performance is then evaluated using a traffic simulator in which every individual is assumed to their perceived shortest route based on updated link travel time information acquired through the social network. The analysis shows that the most effective countermeasure is to supply accurate information to a number of regional leaders that is appropriate for the network size.
