It is well known that the seismic performance of transportation systems plays key rolls for the post-earthquake emergency management. It needs to be evaluated from both physical and functional view points. This research deals with the fragility functions that can be used for post-earthquake management of transportation systems where both space and time factors are relevant.This research developed a methodology for evaluating the seismic fragility function that takes both physical and functional aspects into account, and carried out an example analysis for the Hanshin expressway. The basic data that describe physical and functional characteristics of the highway system under the 1995 Hyogoken-Nanbu earthquake was provided by Hanshin Expressway Public Cooperation. This research (1) constructed the GIS-based damage database and developed the seismic fragility functions for the highway bridges ; (2) summarized the recovery and reconstruction process and developed the fragility function of the bridge reconstruction ; (3) established a methodology for estimating OD values under the disaster condition.In addition, for evaluating the post-earthquake highway system recovery, (4) the database for the process of the recovery and reconstruction works was developed, and based on that, the recovery time was calculated by bridge type.The functions developed in this study evaluate both physical and functional aspects of the seismic performance for highway systems and are used to demonstrate for estimating seismic losses due to earthquakes.

众所周知，交通系统的抗震性能对于震后应急管理至关重要。需要从物理和功能两个角度对其进行评估。本研究涉及可用于空间和时间因素相关的交通系统震后管理的脆弱性函数。本研究开发了一种评估地震脆弱性函数的方法，该方法考虑了物理和功能方面，并且以阪神高速公路为例进行分析。描述 1995 年兵库县南部地震时公路系统物理和功能特征的基本数据由阪神高速公路公共合作社提供。本研究(1)构建了基于GIS的损伤数据库并开发了公路桥梁的地震易损性功能； (2)总结了桥梁恢复重建过程，开发了桥梁重建的脆弱性函数； (3)建立了灾害条件下OD值的估算方法。此外，为了评估震后公路系统的恢复情况，(4)开发了恢复重建工程过程的数据库，并在此基础上，本研究中开发的函数评估公路系统抗震性能的物理和功能方面，并用于演示估计地震造成的地震损失。
