Optimized Scheduling Of Urban Composite Line Transfer Bus Schedule

With the rapid development of domestic economy,private car ownership rate increases,traffic congestion has become a normal.In recent years,in order to create convenient and fast urban transportation,the government and planning departments make full use of urban limited resources to vigorously develop public transportation,so as to promote the orderly development of urban transportation more efficiently.Under the background of the rapid development of the city,the preparation of the bus timetable has become an important link,and the perfect timetable is an important bridge connecting the operating benefits of the bus enterprises and the interests of passengers.The research purpose,content and corresponding technical route of this paper are determined by reading the relevant literature at home and abroad.Then introduces the collection and analysis of bus passenger flow data,and describes the research status of schedule preparation and related theory.By analyzing the operation relationship between bus lines and the passenger transfer method at station,the research objects are: single point intersection line and continuous intersection line.The transfer relationship between vehicles is discussed in the order of arrival.The type of stranded passengers and additional waiting time,and analysis of different models Analysis of transfer stations;use the BCL model,analyze the subjective and objective influencing factors of transfer on passengers,and establish the selection probability model of different stations;calculate the transfer amount of each station according to the transfer demand between lines and station selection probability mode.The reliability of the model and algorithm was verified by analyzing the single-point intersection line of 710 and 908 and 708,522 and 101 in Dalian,Liaoning Province.Firstly,the actual survey data,basic parameters and passenger flow distribution were analyzed;Secondly,all kinds of characteristic variables of data were introduced into BCL model and various group simulated annealing hybrid genetic algorithm,using MATLAB software to obtain the required bus departure interval schedule.This timetable is to optimize the original departure interval to reduce passengers without changing the starting time and resources The tention time thus confirms the true reliability of the model and algorithm.
