Abstract
This paper addresses an evaluation methodology for function of a transportation network in emergency injured transportation. In the post-earthquake emergency response phase, the traffic time delays due to damage of the transportation system has a significant effect on the earthquake casualty. The index of life-saving performance is proposed in the term of survival ratio of injured people. The simulation of injuries transportation has been done by a decision detecting the fastest destination to a hospital, considering both malfunction of transportation system and hospital, which can accept the injured people.
