Abstract To generate the adequate routing path for rescue traffic to reach disaster area after an earthquake is the kernel of an effective traffic management system for post 如何在地震發生後產生救災所須之交通路徑 ，支援救災 earthquake rescue action. In this paper, a routing model is 交通管理作業，是一個地震救災交通管理系統的一個核心工 created under consideration both of road section disruption 作。因此，本研究利用地震可能造成阻斷道路的風險 ，結合 risk caused by collapsed building and of traffic congestion loading by heavy emergency travel demand. Using utility 交通負荷對於交通阻塞的影響，組成聯合效用函數建立地震 function to integrate the road disruption risk and travel time 救災之最小風險路徑選擇模式，以供網派災及運送物資車輛
