Optimization of cross-line train operation scheme of urban rail transit based on OD passenger flow

With the improvement of urbanization level and the continuous expansion of urban scale, the traditional single-line operation mode has gradually been unable to adapt to the existing diversified passenger flow needs, and various urban rail transit is also transforming to networked and interconnected operation. How to develop a matching train operation plan based on the needs of passenger flow has become the primary problem to be solved. Based on the cross-line OD passenger flow, this paper analyzes the travel choice behavior of different OD passengers to establish a model of urban rail cross-line train operation. Finally, combined with the actual data of two lines in a city that meet the cross-line operation, the feasibility of the model is verified, and the passenger flow conditions required to operate the cross-line train are determined, compared with the single-line independent operation scheme, the implementation of cross-line operation can reduce the operating costs and passenger travel costs of enterprise.
