Research On Urban Public Traffic Route Selection Model Based On Travel Information

Although the rapid development of the economy to bring people's convenience,but the cause of the increasingly serious traffic congestion problems let the traveler miserable.In order to alleviate the traffic pressure,it is necessary to improve the sharing rate of public transport in urban traffic.However,with the continuous development of urban transport,residents of the travel mode and the choice of path requirements are also increasing.Although the traveler information system(ATIS)is evolving,it provides a lot of travel information for the traveler,but in some cases its recommendation for the optimal path does not meet the actual needs of the traveler.Therefore,this paper studies the choice of public transportation travel route under the premise of travel information,constructs the generalized travel expense model based on the purpose of travel,and validates the general applicability of the model by case study.This paper first gives a brief overview of urban public transport trips.Based on the introduction of urban public transport classification,this paper analyzes the influencing factors of travel mode and thinks that the purpose of trip will affect the choice of travel mode to a great extent.At the same time,the cost,time,comfort and reliability of the four factors in the impact of travel on the basis of convenience will affect the choice of travel mode.Secondly,according to the characteristics of urban public transport network,the urban public transport travel network model based on topology network is established,and the generalized cost function is constructed on the basis of the purpose of travel.Based on this,the proportion of each indicator in the generalized cost function is calculated.Finally,on the basis of the unique characteristics of public transport network,the traveler routing model is described mathematically,and the algorithm design of this paper is put forward.Then the validity of the path selection model is verified by an example.The research results of this paper provide some research ideas for the further improvement of the traveler's information system,which facilitates the residents' travel and satisfies their individual travel demand.
