Study On The Connection And Optimization Of Rail Transit Network With The Last Bus

The connection between the timetable of urban rail transit and the last bus of a bus can reflect the overall service level of urban public transportation to a certain extent.During the rapid development of urban economy and the development of public transportation from linear to mesh structure,residents gradually have higher demand for the last bus trip of urban public transportation.How to scientifically and effectively arrange the departure time of the last bus of urban public transportation has become a key issue that needs to be researched and solved urgently.This paper mainly studies the optimization of the connection between the meshed urban rail transit and public transport,as follows:(1)Summarize the current status of the preparation of the last train timetable,and compare and find the current problem of the transfer connection method of the last train.It is proposed that the preparation of the timetable of the last train timetable should put the connection between the transfer station line and the line in a more important position.To this end,the waiting time for passengers is reduced to improve the efficiency of transfers.In addition,the current schedule preparation method and the behavioral psychological analysis of passenger transfer are used to optimize and improve the energy consumption direction of passenger transfer,providing a theoretical basis for the model establishment.(2)In the study of the different importance levels of the transfer direction at the connection point of the last train and the quantitative evaluation criteria of the transfer conflict,the importance of the transfer direction and the direction intermediate of the transfer node are set as the evaluation criteria and the values ? ? are determined.After the optimization object is determined,the optimization objective function is from "the minimum energy consumption of the overall passenger travel","the maximum number of passenger transfers",and "the minimum degree of discrete operation time at the end of the line".Taking into account the actual travel needs of passengers on the last train and business operating costs and safety issues.(3)The actual case analysis of the road network structure using Dalian Metro Line 1 and Line 2 and three networked public transit lines with high coverage of public transit lines in Dalian as the road network structure shows that the relative As far as the performance of the last train is concerned,all the indicators of the improved optimized connection model have been improved to a certain extent.Among them,"Total Passenger Energy Consumption" has decreased by 9.23%,and "Passenger Transfer Success Number" has increased by 33.33%."The last operation time of the last train" increased by 10.92%.In addition,the total number of connections for the last bus at each transfer station has increased by six compared to the previous direction.Therefore,it proves the practicability and effectiveness of the model in this paper.
