Analysis of people's route and destination choice in evacuation using GPS log data

Abstract

Tohoku Earthquake, which occurred on March 11th 2011, resulted in the failure of public transportation system affecting over 5 million commuters. They were forced to choose their destinations and routes abnormally and that situation in which roads and public facilities are flooded with commuters increases the risk of secondary disaster. Therefore, clarifying the properties of evacuation behaviors is important for the mitigation of natural disaster. Today, due to the development of sensor and information technology, enormous and objective data about people's behaviors can be automatically obtained. In this paper, we analyzed the GPS records from mobile devices of large number of people for half a year, including the day of Tohoku Earthquake and estimated the daily commuting route and routes people went through after Tohoku Earthquake on 3.11 using road network.
