Abstract
In this Paper, a simulation model to evaluate disaster medical conveyance system for wide area disaster was developed and simulated on Shizuoka City using data of estimation of Tokai Earthquake. This simulation model using spatial data of spatial, fire station, roads and so on is able to evaluate the efficiency of medical conveyance system. The effectiveness of information sharing between ambulance and hospitals, and triage on the site to shorten conveyance time and treatment time was analyzed. As a result, the importance of information sharing combining with the usage of triage was found to improve the efficiency of disaster medical conveyance system.
