Abstract
The transport for the injured is one of the important activity at a serious incident. However it has never been handled fully up to now in the incident response plan. The study aims to give evaluation indices for the many injured when a serious incident occurs. We define three kinds of risks; the transport risk, the medical confusion risk, the left behind risk. Then we try to calculate the value of each risk by a mathematic model. As the results of case studies that the Garuda Indonesian airplane accident and the Shigaraki train accident, it proves that it is available as benchmarks for evaluation of transport activity.
