Study On The Bus Scheduling Method Of Urban Comprehensive Passenger Transport Hub

With the increasingly close connection between cities,a variety of urban comprehensive passenger transport hubs have been established for the effective connection between cities and cities.Due to the imbalance between the passenger flow information and the urban traffic information in the comprehensive hubs,some traffic modes are likely to be crowded,while others are not occupied,resulting in the unreasonable utilization of public resources.In this paper,the comprehensive passenger transport hub city bus scheduling problem is studied,first of all,from the comprehensive hub passenger flow distribution characteristics were analyzed,and then consider the leading transportation transfer bus passengers and the non-dominant transfer to bus passenger demand,optimize the bus departure schedules and vehicle scheduling,considering the passengers’ transfer to experience and transportation efficiency and total operation cost of the bus company,in the case of satisfy passengers transfer to experience,reduce bus total operating costs,improve the grid average load factors,so as to enhance bus passenger evacuation ability.This paper first summarizes the characteristics and functions of the urban comprehensive passenger transport hub,and analyzes the passenger flow in the hub from the perspective of distribution characteristics and time distribution.Secondly,it studies the influencing factors of bus scheduling in urban comprehensive passenger transport hubs.First,it expounds the operation scheduling mode of ground buses and the scheduling method of hub buses,and analyzes the influencing factors from the perspectives of urban structure,hub planning,bus companies and transfer passengers.Then based on the through from the bus service level of car bus regional scheduling scheme are studied and optimized,in the case of without changing bus lines,and other traffic mode change to the single direction of the research line bus transfer passengers as the research object,establish passenger transfer to the total cost and the total time,bus operation start three bus scheduling optimization model,the average load factors based on multi-objective optimization feature selection NSGA-Ⅱ.Last study of Chongqing city public transportation and the hub of Chongqing north station,taking Chongqing north station north square bus hub station 141 lines,245 lines,354 lines,849 lines as the research object,choose 17:00-20:00 late peak period as the research period,according to the model,as the research line bus during the study period with departure schedule after optimization and bus dispatching scheme,starting with the original schedule,single line scheduling scheme and regional scheduling scheme comparison,proved that urban comprehensive passenger transport hub bus the feasibility of using regional scheduling,The maximum number of available vehicles can be reduced,the total transfer time of passengers can be shortened,and the number of stranded passengers can be reduced by reasonably arranging the departure time.Therefore,the bus scheduling method in this paper can be helpful to the practical application,and in the future research,the author prospected the bus scheduling problem of urban comprehensive passenger hub and gave the direction of further discussion.
