Title The urban rail transit power supply system based on road traffic impedance emergency site location model

Abstract With the deepening of the process of urbanization and motorization,the urban rail transit as an important transportation way of easing traffic congestion plays a more and more important role。Based on the orbit transportation emergency under the road traffic impedance site selection problem of study,to improve network operation condition of urban rail transit emergency safeguard efficiency is of great significance。

Firstly,rail traffic emergency management is presented in this paper based on the analysis of the status quo,system analysis and network rail transit power supply system of emergency management efficiency factors,establish the location of the emergency power supply system site maximum coverage model,and capable of the relevant theories of the short circuit and the Dijkstra algorithm for solving the model。Secondly,according to the result of model calculation to determine the emergency site location scheme can effectively reduce emergency response time,optimization of emergency resource allocation efficiency,improve the level of emergency site service。Finally,validated with Nanjing Metro as an example analysis,validation results show that the model and algorithm has certain practicability and application value。
