Issues and Future Prospect on Practical Use of Probe Vehicle Data for Disaster Reduction -Provision of the Vehicle Tracking Map in the 2007 Niigataken Chuetsu-oki Earthquake-

Abstract

Road information is one of the most important information for vehicles of emergency service, rescue and other disaster response organizations. However, it is difficult to get ever-changing road status of wide area in real-time, and sufficient road information is not provided in actual disasters. In this paper, we report the experimental provision and its problems of the vehicle tracking map in the 2007 Niigataken Chuetsu-oki earthquake, as part of effort to apply probe vehicle data to disaster reduction. We indicate possibility of road damage estimation using probe vehicle data by real data analysis. Issues and future prospects for application of probe vehicle data to disaster reduction are discussed.
