The Research On Route Optimization Of Customized Feeder Transit System Oriented On Inter-city Railway System

With the process of urbanization and motorization in China keeps growing,urban transport gets worse and residents commuting becomes harder.Citizens are more tend to diversified,personalized traffic travel modes and high quality,efficient transportation services.So the multiple public transport system which takes rail traffic as the backbone and diversified ground traffic as the network has become the inevitable trend of the development of public transport system in China.Therefore,in this thesis,the passenger fast-track intercity rail transit as a starting point to serve the intercity rail transit site of the customized feeder bus system for the study,discusses a new flexible transit service mode--customized feeder services,and mainly focus on the optimizing of routing considering the time table of intercity rail transit.First of all,aiming at the characteristics of urban structure,the type of intercity rail transit stations and the characteristics of passenger flow,this thesis analyses the applicability of customized bus service system to intercity rail transit,and puts forward the research object--Customized feeder services for intercity rail transit.Secondly,the thesis draws out the service characteristics,working principle and key factors related to the system design of the customized bus connection,which is suitable for connecting the rail transit,and combines the actual operation characteristics of the new bus service system,describe the operation of the customized feeder service system.Thirdly,taking into account the interests of the operating enterprises and the passengers,the route optimization model is established based on the maximum meet customized passenger travel demand,connecting to minimize vehicle operation cost and time cost of passengers.The constraints of the model include order matching vehicle constraint,the reasonable path constraint of the vehicle,the rated capacity constraint of the vehicle and the time window constraint,and the simulated annealing algorithm is designed to solve the model.Finally,the feasibility,validity and stability of the optimized model of the customized feeder route planning model are verified by a case study.The results of the research have a certain contribution to the enrichment and development of the customary bus system theory,and it is of great significance for the city to open the route planning for the interchange of intercity rail transit.
