考虑多元乘客偏好的多交路市域快线开行方案优化研究OA

To accommodate the passenger flow characteristics of regional express lines and develop a multiple-route operation plan that meets the diverse needs of passengers,this study selected a regional express line passing through an aviation hub and an urban terminal as the research object.First,the preference characteristics of various passenger types and their differences in willingness to pay for factors such as travel time and comfort were described,serving as inputs for calculating the costs of different passenger types when choosing specific operation schemes.The arrival time distribution functions corresponding to each passenger type were fitted to calculate their waiting time at stations.For multiple available train operation routes and various train types,an optimization model for the train operation plan of multiple-route regional express lines considering diverse passenger preferences was constructed with the objective of minimizing operation costs and passenger travel costs,taking into account constraints such as passenger flow demand,train capacity,and operational capabilities.A case study was used to verify the model's effectiveness.The results show that among three stop-plan schemes with decreasing numbers of stops for each route,the proportions of 200 km/h high-speed trains operated are 32.26%,36.00%,and 60.00%,respectively.This indicates that the model can fully leverage the advantages of trains with different speed levels.By adjusting the weight coefficients of operation costs and passenger travel costs,train operation plans adapted to different operational needs can be generated.In terms of model performance,compared with scenarios where passenger preference and perception coefficients are set uniformly,a differentiated configuration of these coefficients,tailored to passenger types and travel preferences,can reduce both total travel time and overall costs for all passenger categories.Using the homogenized coefficient scenarios as a baseline,the results demonstrate that the differentiated approach effectively enhances the fulfillment of passenger preferences.The model proposed in this study can provide a reference for formulating train operation plans for regional express lines based on passenger preferences.
