Route Optimization Of Customized Flexible Line Feeder Bus For High-Speed Rail Station

With the rapid development of China's high-speed rail,intercity high-speed passenger transport network has been gradually improved,and intercity space and time distance has been greatly reduced.However,there are many problems in the passenger transport connection network caused by fragmentation.Although all the high-speed rail stations have built a transfer bus passenger station,most of them use class line transportation,it is difficult to easily enjoy the high-speed rail service in the areas with low density demand.The basic and cohesion of road passenger transportation with the advantage of "Door to Door" have not been fully played.With the continuous improvement of "Super-Ministry System","Big Traffic" is gradually forming.How to build a seamless connecting passenger transport system with "high efficiency,fair,low carbon and high quality" has become an important problem to be solved urgently in the current traffic and transportation industry.First of all,through the investigation of the passenger transport characteristics of the high-speed rail station,the regularity of passengers' personal attributes,travel characteristics and service properties,as well as the characteristics and rules of passengers' travel connection are clarified.This thesis summarizes the existing passenger transport connection modes and their advantages and disadvantages and their applicability,and puts forward a custom flexible feeder mode suitable for the high-speed rail station,and designs the corresponding feeder bus system,which can provide the service for more people.On the basis of this,considering the dynamic of the traffic network and the customization and dynamic of the passenger demand,the dynamic shortest path model based on the time-varying traffic network and route optimization model of customized flexible line feeder bus for high-speed rail station are established.These models are more close to the actual situation.Then,according to the characteristics of these models,the commonly used algorithm is analyzed,and the Ant Colony Optimization is optimized,and it is used to solve these models established in the thesis.Finally,a virtual traffic network is constructed to verify the effectiveness of the model and algorithm.
