Abstract
The suburban railway adopts the mode of combined operation of express and local trains, which can solve the problems of uneven temporal and spatial distribution of passenger flow, meet the diversified needs of passengers, improve transportation efficiency and reduce operating costs. By analyzing and summarizing the passenger flow characteristics and transportation demand of suburban railway, aiming at minimizing the total travel time of passengers and enterprise operating cost, a nonlinear optimization model of suburban railway operation scheme is established. Considering the influence factors such as minimum tracking interval constraint and cross-sectional passenger flow constraint and completes the solution of the model by Lingo. The optimization results after running express and local trains show that the total travel time of passengers is reduced by about 97 minutes, and the enterprise operating cost is reduced by 30%, which proves that the proposed model is efficient and feasible.
