Study On Route Optimization For Feeder Bus Of Highspeed Railway Station In Small And Medium-sized Cities

With the rapid development of high-speed railways in recent years,high-speed railway stations in small and medium-sized cities go into operation gradually.However,in some small and medium-sized cities,high-speed railway stations located far away from the main city,bringing trouble to residents who want to transfer to high-speed railway.At present,feeder bus is one of the main means of providing transfer services for passengers in small and medium-sized cities,how to make the feeder bus meet the transfer requirements of residents better,and improve the service efficiency of the feeder bus,is one of the key issues in the current planning of small and medium-sized cities.This study combines the main travel characteristics of passengers in small and medium-sized cities to explore a route optimization method for the feeder bus of high-speed railway station in small and medium-sized cities,and the main work includes the following parts:(1)The feeder bus of high-speed railway stations in small and medium-sized cities are introduced and their characteristics are analyzed.Firstly,the characteristics of small and medium-sized cities and high-speed railway station are analyzed,and then the definition,classification and characteristics of high-speed railway stations are introduced,and the status of high-speed railway station in Changshu is briefly analyzed,and some problems existing in the current status of feeder bus of high-speed railway stations in Changshu are sorted.(2)A survey on the willingness to travel by feeder bus of high-speed railway station is conducted.First of all,the purpose and content of the survey are clarified,and secondly,the RP and SP survey methods are combined to investigate the passengers’ personal attributes,travel preferences,and passengers’ travel willingness to change before and after the optimization of the feeder bus of high-speed railway station,and according to the survey results,the main factors affecting the current passengers’ travel willingness are summarized through applying statistical analysis and Logistic regression analysis.(3)The selection method of feeder bus stations and the optimization method of routes of feeder bus of high-speed railway stations are explored.Firstly,based on the analysis of the influencing factors of passengers’ travel willingness,the selection optimization model for the group of feeder bus station is constructed,and the genetic algorithm is used to solve it.And then the optimization model of the route of feeder bus is constructed,and according to the characteristics of the model,a genetic algorithm who improved the elite selection strategy is designed to solve the problem.(4)Taking A medium-sized city called Changshu as an example,the simulation and optimization experiments of the feeder bus routes of Changshu High-speed Railway Station and Changshu High-speed Railway West Station are simulated and optimized.First of all,according to the actual high-speed railway trips in Changshu City,according to the proportion of population in each community,a set of data on the amount of feeder bus travel that is closer to the actual situation is estimated,and then the optimization method for the selection of feeder bus stations on high-speed railway stations is used to simulate feeder bus stations on high-speed railway stations and the sensitivity analysis experiment is carried out.According to different route modes of feeder bus of high-speed railway station,different passenger flows and different energy consumption costs,the route generation optimization is experimented on,and the experimental results are compared and analyzed to verify the effectiveness and feasibility of the model and algorithm.
