基于NestedLogit的小汽車通勤出行轉(zhuǎn)移模型研究
[Abstract]:With the expansion of urban space, the separation of urban residents' occupation and residence becomes increasingly prominent. The separation of employment place and residence makes the average commuting distance and commuting time of urban residents increasing day by day, and the commuting travel problem becomes more and more serious. Among all kinds of travel purposes, the commuter travel ratio is as high as 40%, and the morning and evening peak travel volume with commuting as the main body is too concentrated, which intensifies the contradiction between supply and demand of the transportation system in the city. Therefore, it is very important to solve the problem of commuting travel for alleviating urban traffic congestion. Based on the investigation of the intention of car commuters to public transport, this paper analyzes the characteristics of commute travel of cars and buses, the commuting modes and the factors affecting the choice of departure time. In this paper, the Nested Logit model of commuting departure time and mode selection is constructed, and the influence of setting bus lanes on the transfer of cars to public transport is analyzed. It provides a reference for the formulation and implementation of policies to alleviate urban traffic congestion. Firstly, this paper introduces the research background and significance of this paper, summarizes the current research situation at home and abroad, and then puts forward the research content and technical route of this paper. Some basic concepts and theories used in this paper are defined and expounded, Tongzhou area is selected as the investigation area, the required data are obtained by using RP SP survey method, and the variance discriminant method is used to score the data. The logical calibration method is used to filter and modify the data. Then the characteristics of commute travel and the attribute of commuter are analyzed. Finally, the Nested Logit model of commute departure time and travel party selection is constructed. The model is used to calculate the transfer rate of five kinds of commute modes from cars to public transport. The main conclusions of this paper are as follows: the number of cars, the age, the annual income of the family, the travel time difference between the bus and the car, the rising cost of the car, the ticket price of the bus, the degree of congestion of the bus are the main factors influencing the commuter's travel mode choice. The main factors that affect commuters' choice of departure time are age, whether there are children to and from school, working hours, annual income of family, number of cars and travel distance. And the earlier they start, the more likely they are to choose public transport; because the cost of each trip can be regarded as a fixed level in general, and with the increase of the cost per unit time of the car trip, it means that the commuting time of the car is shortened. Therefore commuter choice bus travel probability is decreasing.
