Abstract
China is situated between the Eurasian seismic belt and the Circum-Pacific seismic belt, therefore earthquake ofte happened on it. In recent years, earthquakes have occurred frequently in China, such as the Jiuzhaigou earthquake, the Yushu earthquake, and the Wenchuan earthquake. The damage caused by these earthquakes to the urban road traffic system will lead to the paralysis of urban functions, which will directly affect the speed of post-earthquake rescue and increase the difficulty of rescue. In order to quickly assess the resilience of urban traffic after the earthquake, and then develop emergency evacuation and rescue routes, based on the reliability evaluation method of road network, this paper gives the calculation method of urban road network traffic reliability. Reliability determines the time necessary for the road network to return to normal capacity after the earthquake. The recoverability model of urban road network is evaluated through the established urban road network recoverability model, and the model is used to evaluate the recoverability of some road networks in Zhongshan District of Dalian City, and the prosperous area of Zhongshan District in Dalian is obtained. Part of the road network can recover better after the earthquake.It can provide reference for post-earthquake emergency rescue, avoidance and evacuation, medical rescue and other work.
