| Summary: | 碩士 === 逢甲大學 === 都市計畫所 === 100 === This research is an empirical study of Taichung County. There are two main parts.First, it got the fragility curve through database of road network, and estimate for road’s safety level by joint probability density function and order statistics. this can be the basis for planning the emergency network.
Second, the road’s safety value be the safety index, and the travel-time cost be efficiency index. In order to integrate the safety and efficiency, the“Utility Theory” is adopted as the framework to evaluate the utilities and to judge the priority of factors. Than we substitution utility value into linear programming model, and than has acquired a optimal solution. final we compare optimal solution with minimal distance solution and sensitivity analysis for the study solution are reasonable or not.
