| Urban passenger corridor is core area of urban development,burdening mass traffic flow and being,and is the main area traped into traffic jam.Striving to develop public transit system is main direction to alleviate traffic congestion of urban passenger corridor.Recently,the functional orientation of bus lines in urban passenger corridor is vague and line overlap factor of bus lines is higher than code value.How to lift the efficiency of bus lines in transit corridor and effectively organise public transport passenger flow are main research contents.The studied passenger corridor is the corridor on urban scale.The characteristics of urban passenger corridor are analyzed from three aspects,including the bus-route characteristic,mutil-mode public transport system and traffic infrastructure.The technical indexes of these different public transport mode are summarized and the grade of passenger corridor is divided.In order to analyze the characteristic of passenger flows in urban passenger corridor,the method to judge the starting station based on the IC data and AVL data and the probability model to judge passenger alighting station based on attraction ability of bus station are proposed to support the analysis.Propose the various indexes to organise and optimize the passenger flow.These methods and indexes are used to offer technical and data support for organizing and optiming corridor passenger flow.The corridor passenger flow are organized and optimed through two aspects,including bus lines deploy and transit operation optimization.Firstly,proposing multi-path transit section passenger flow assignment methods based on Logit model and building parallel structure net work between bus rapid transit and conventional public transport.BPR function and transit operational data are be used to describe link impedance function respectively.According to the section passenger,the bus line deploy method of bus rapid transit and conventional public transport is put forward.Take Changzhou Tong jiang road corridor as an example to analyse the reasonable bus line deploy scheme.Secondly,on the basis of bus line deploy,come up with express vehicle combinational scheduling and short-turn vehicle combinational scheduling models.The objective funtion of the model takes the total costs for both operators and passengers.The genetic algorithm is used to solve the models to get scheduling plan.Take B1 and line 18 in Tong jiang road corridor as examples to obtain the optimal scheduling plan.Compared with current transit scheduling plan,the total costs decrease significantly,which indicates that combinational scheduling can promote transport efficiency of bus lines in urban passenger corridor effectively. |
