| Abstract: | The traffic network is base of implement rescue activities.Two kinds of methods that identify the condition of post-disaster road network are proposed： based on simulation and combine aerial technology with GIS.Vulnerability index that assess road network characteristics are put forward.Bi-level planning model for road network restore is constructed,and the optimization algorithm is given.At last,a part of road network of Wenjiang center area in Chengdu is analyzed. |
