Study Of Bus Transportation Network Accessibility Based On Random Utility

In recent years,with the improvement of living standards of urban residents,the problem of traffic demand is becoming more and more prominent.The use of limited land resources to establish a sound public transport system is the key to solve this demand problem,and reasonable planning of conventional terrestrial public transportation network more effective realization of urban land resources.As an important index to evaluate the service level of public transportation system,traffic accessibility can not only be used to evaluate the status of the layout of public transportation network,but also can play an important practical significance for further optimization of public transportation network.Based on the accessibility theory,the general public transport network accessibility is defined as the broad generalized utility obtained by the traveler from the starting point to the destination through conventional terrestrial public transport.From this definition,the travel demand and routine Main Factors Affecting Public Transport Network.According to the characteristics of the traveler and the characteristics of the routine bus travel,the paper analyzes the behavior of the residents' routine bus travel route selection,and establishes Multivariate Logit Model including the variables of the characteristics of traveler,travel time,transfer times,bus service quality and bus network connectivity.The model is based on the theory of stochastic utility and the discrete choice model as the frame structure.The SP/RP combination survey method is used to obtain the data needed by the model.Then,the SPSS statistical software is used to process the survey data,and the unknown parameters in the multivariate logit model are calibrated and validated.Finally,the model can accurately calculate the public transit Travel decision-making behavior description,and apply to the city routine bus network accessibility evaluation.
