融合视角下市域轨道交通线路规划模型
Suburban rail transit line planning model from perspective of integration
摘要
Abstract
There are diversified passenger flow demands such as hourly reach and commuting along the route in the city area of the center city of metropolitan area,while the structural supply of urban rail transit lines is insufficient.In order to solve the problem of diversified line integration planning(fusion),this paper constructed an objective function of the number of hours of spare line interval capacity using the line station selection,frequency of departure,speed configuration,and the amount of inter-station passenger flow distribution as the decision-making variables,to measure system operating cost,a more difficult indicator to calculate.At the same time,the objective function of total passenger on-board time was constructed,and the constraint relationship between passenger flow demand,line capacity,station spacing and speed class was considered.Based on the principle of minimizing the objective function,the urban rail transit line planning model under the perspective of integration was proposed.Adaptive Large Neighborhood Search Algorithm with Simulated Annealing Mechanism(SA-ALNS)was used to solve the model,and the speed advantage of the algorithm in searching for the optimal solution was proved by comparing it with the mathematical solution method,and the comparison of the solution performance with ALNS without Simulated Annealing Mechanism proves the algorithm's superiority in searching for the global optimal solution.The results of the study show that compared with the established scheme,the number of spare hours of the inter-area capacity of the line scheme planned by the model has been reduced by 16.5%,the total passenger on-board time has been reduced by 32%.The total objective has been optimized by 26.8%,which can prove the effectiveness of the model.The model is able to find the Pareto equilibrium solution of the system in the case of conflict between objectives 1 and 2,which can prove the multi-objective optimization ability of the model.At the same time,the model is also effective and significantly better than the established program for the route planning scheme of other corridors,proving the applicability of the model.The model can provide theoretical support for city rail transit line planning,which helps to accelerate the construction of city rail transit.关键词
