Research On Bus Travel Path Selection Behavior Based On APTS Data

As an embodiment of bus system automation and intelligence,Advanced Public Transportation System applies global positioning,wireless communication and other technologies to realize intelligent bus operation scheduling and informatization of bus operation.APTS provides the location,route and geographic information of the bus stop through the unified organization and scheduling of the bus.Taking the information data provided by the intelligent bus system as the medium,the dynamic,randomness,spatiotemporal characteristics and supply-demand relationship of the bus network are studied.Furthermore,it analyzes the factors that influence passengers’ travel modes and routes,which are also important indexes to evaluate the service level of public transportation system.Therefore,it is of great practical significance to mine the information behind the APTS data and study the urban bus route selection behavior for improving the planning and management level of the public transport system and guiding passengers to travel.Firstly,this paper summarizes the development process,basic theories and current research methods of path selection behavior.And on the basis of APTS data,the judgment of bus passenger boarding station,the judgment of getting off station and the calculation of getting off time are realized.The APTS data were organized,the bus trip chain database based on the city bus system was constructed,and the OD pairs of trip data were extracted with t-sql statement.Through this set of complete data processing method to extract OD data of path selection has the characteristics of strict logic and high accuracy.Secondly,carried on the detailed analysis the characteristic of bus travel,from three dimensions of travel time,travel distance,travel frequency,with travel time and its reliability as the breakthrough point,determine the analysis indicators and from two aspects: overall and specific OD data to analysis the characteristic of bus passengers,on different travel time and trip distance,the characteristics of different path of passenger travel time,differences are analyzed.Thirdly,from the perspective of bus route,this paper analyzes the passengers’ path choice behavior,establishes the path characteristic index based on the road capacity and traffic service level,and obtains the correlation between the path characteristic parameter index and the path choice behavior.Finally,based on the random utility theory,based on chaotic more public transport route choice classification Logit model,with different OD pair,different direction and path choice of travel time data for model calibration,the variables from a large number of model calculation results,with the result of the influence degree of the path selection and the factors influencing the path choice of marginal utility analysis,explore the sensitive degree of route choice behavior influence factor.This article from the subject and object of route choice behavior,namely two passengers and path,this paper analyzes the factors which influence on public transportation route choice behavior,the public transit route choice and the combination of travel time reliability,adjust the bus route,for planning and to improve public transportation service level,the reasonable use of public transportation capacity to provide the technical support.
