Abstract
Regional rail transit is a kind of comprehensive railway transportation system, which originates from the demand of economic integration of city groups and contains various kinds of sub-transportation systems such as high speed railway, inter-city railway, subway and monorail. Due to the deficiency of coordination between different kinds of transportation systems, the global risk of regional rail transit network greatly increases. Therefore, it is urgent to evaluate the rail transit network safety from a global perspective and enhance the safety through coordinative optimization. To address this problem, a method to evaluate the global safety of regional rail transit system based on passenger flow demand load is proposed, a mathematical model to minimize the global risk of rail transit network is constructed, and the global safety is enhanced by coordinative optimization of passenger flow assignment and train scheduling. An example on the regional rail system in Chengdu-Chongqing district validates the effectiveness of the proposed method. Compared with the method in the literature where only passenger flow assignment is considered, the example shows that the proposed approach can bring a further 10% decrease of the global risk of rail transit network.
