The Study On Routes Optimization Of Urban Custom Bus

With the acceleration of China's urbanization process and the development of the society,making the job separation problem more and more serious,and people pay more attention to the phenomenon of tidal transport,the problem of commuting and other issues.Therefore,many cities begin to try a new transport model,called custom bus.Custom bus is a kind of direct bus which is from the cell to the unit based on an information technology platform.The background data center will design corresponding bus lines according to the personal demands putting forward by passengers,such as travel origin,destination and commuting time.Custom bus is a demand oriented public transport mode serving for people who have similar needs,travel time and destinations.The process of the development in custom bus appears a variety of problems,from the routes optimization perspective,this paper analyzing both the domestic and foreign researches on the routes optimization of bus,shuttle car and other related combined with the characteristics of urban custom bus,sort out the main differences between regular bus and custom bus and the key problem in optimizing routes.Taking time constrains into fully consideration,this paper establishes a multi-targeting optimization model of custom bus lines,with the goal of maximum operating benefit and the maximum rate of services coverage,which makes a contribution to improving public transport market and alleviating the public traffic demand contradiction.It is of great practical significance to promote the development of green traffic.The study can not only make up the lack of existing theory research,but also provide future transit operator with some new ideas in lines arrangement,so that enhance the level of public transport services.This paper mainly studies the following aspects:Firstly,this paper summarizes the domestic and foreign scholars' research of the custom bus route optimization,including custom bus theories and route optimization theories related to the paper,and expounds the importance of researching in the optimization of custom bus lines.Secondly,this paper expounds the connotation of the custom bus in detail and takes several typical places at home and abroad as examples,and summarizes the main differences between the custom bus and urban public bus and the business shuttles.Thirdly,based on a large number of references of route optimization and ant colony algorithm,the paper takes time constraints,the attendance rate and path length into consideration,establishes a multi-targeting optimization model which seeks for the maximum operation profit and the maximum service coverage,and solves the model with improved ant colony algorithm.At last,taking tourists' demands data of city A's administrative service center as an example,this paper proves that the algorithm can solve the model and the line optimization model can balance the benefits and service quality.
