| In the process of my country's new urbanization,large cities have led surrounding cities to form a new urban form-metropolitan area.Cities in the metropolitan area have developed through frequent economic exchanges and clear division of labor.At the same time,along with the internal changes of the metropolitan area,the accessibility of the metropolitan area has improved,and the demand for intercity travel has further increased.In order to ensure the sustainable development of the transportation system of the metropolitan area,the key to the problem is to explore the changing laws of the intercity travel structure during the development of the metropolitan area.This thesis conducts an in-depth study on the changes in intercity travel decision-making after the improvement of urban traffic accessibility.This article mainly analyzes the characteristics of intercity travel in the metropolitan area,and explores the main intercity passenger transport modes in the metropolitan area and the factors that affect travel decisions.First,analyze the accessibility level of the metropolitan area based on the regional accessibility measurement method;then use RP&SP survey Methods: Set up scenarios for improving the accessibility of the metropolitan area,and conduct an inter-city travel decision-making survey on the Jinan metropolitan area;construct the inter-city travel decision-making intention structural equation model based on the expansion plan behavior theory framework,and analyze the factors that affect the travel decision-making intention.The mixed choice model establishes an inter-city travel mode transfer model to analyze the factors that affect travel decision transfer.In the end,the following conclusions were reached:(1)Taking the Jinan metropolitan area as the research scope,combined with future planning analysis,it is found that the speed of railway accessibility is very fast,and the railway travel time between cities is shorter and the cost is lower,which has great advantages.The statistical analysis of the questionnaire found that the improvement of the accessibility of the metropolitan area will affect the choice of inter-city travel modes for travelers.(2)Through the analysis of the influence of travel decision-making intentions,it is found that behavioral attitudes and perceptual behavior control have a significant impact on the behavioral intentions of road passengers and railway passengers;and after the improvement of accessibility,passengers are most concerned about the range and time of travel mode,cost.The difference between road passengers and railway passengers is reflected in the degree of dependence of road passengers on motor vehicles will significantly affect their behavior intentions.(3)After the accessibility of the Jinan metropolitan area is improved,women,elderly,ordinary-income,highly educated,and car-free passengers are more likely to move from road to rail travel;while youth,high-income,middle-to-low education,and car-free travel are more likely to be transferred.Passengers with different characteristics have a higher probability of transferring from railway to highway;the increase in accessibility of metropolitan traffic leads to changes in travel time and travel cost,which have a significant impact on the transfer behavior of travel modes;latent variables also affect the transfer of inter-city travel modes.Passenger travel transfer behavior will be affected by behavior attitude and behavior intention;railway passenger travel transfer behavior will be affected by perceived service quality,behavior attitude,behavior habits and behavior intention. |
