Abstract
Regional rail transit is a composite rail transit system that includes multiple types of rail transit. Compared with single-standard rail transit, the types of risks increase, the risk impact is greater, and the consequences are more serious. Therefore, it is urgent to optimize the allocation of regional rail transit emergency resources to improve the overall efficiency of emergency operation and maintenance. Aiming at the characteristics of regional rail transit, this paper proposes a method for optimal allocation of regional rail transit emergency resources based on resource sharing. Firstly, according to the overall requirements of emergency services, the number of emergency stations is set, and then an emergency resource optimization allocation model for regional rail transit is built based on the p-median model. Secondly, through the multi-standard emergency resource sharing, the overall efficiency improvement of emergency operation and maintenance is achieved. Finally, a case study was carried out using Chongqing regional rail transit as an example to verify the effectiveness of the method.
