- Abstract
In order to meet the development trend of interline operation of urban rail transit network, an optimization model of urban rail transit network train operation scheme under interconnection conditions is proposed from both passenger and enterprise aspects. The model takes the combination scheme and frequency of network trains as the decision variables, and considers the constraints of line passing capacity, number of interchange vehicles and cross-sectional passenger volume to achieve the system cost minimization goal.For the characteristics of the model with many variables, an improved neighborhood search algorithm with search strategy based on rational passenger flow allocation method was designed to solve the model. A case study of a city metro network with four lines was conducted to investigate the optimal operation plan under interline operation. A comparison with the split-line operation was conducted to verify the feasibility of the optimization model and the effectiveness of the algorithm. The results are shown as follows. (1) The improved neighborhood search algorithm with search strategy has shorter solution time and more stable convergence solution quality. (2) Compared with split-line operation, the network-wide system cost is reduced by nearly 4.0% and the networkwide interchange passenger flow is reduced by 4.8% under interconnection, while the operation of interline trains can effectively reduce the business operation cost by up to 40%. (3) The operation of interline trains improves passenger throughness, the number of direct paths increases by 6.4%, and the behavior of multiple interchanges is significantly reduced. (4) To ensure the service level of interline operation, and the number of cross-line routings should be reasonably set, and the actual passenger flow characteristics and passenger time cost of the whole network should be fully considered when using this model. When the hourly entry volume of the network is greater than 97 314 and the interchange coefficient is greater than 1.45, the operation of cross-line is more advantageous than split-line operation.
