The Research On The Choice Of Commuter Travel Mode In Urban Agglomeration

In the context of the new economic normal and the "14th Five-Year Plan" era,China’s urban spatial form has been transformed from a single type to a urban agglomeration.in recent years,due to high housing prices,high cost of living and other factors,some urban agglomeration center residents were forced to move out,some people have a new mode of life.that is,in the underdeveloped non-urban center city to buy a house,work in the developed urban agglomeration city,then evolved a serious situation of job misalcation,Commuters in urban agglomeration phenomenon has become increasingly frequent.Studying the choice behavior of urban agglomeration commuting mode will help to accurately grasp the choice preference and behavior law of urban agglomeration commuters.Based on the analysis unit of individual urban agglomeration commuters,this thesis studies the behavior of urban agglomeration commuters in a single urban agglomeration,and studies the behavior of commuting behavior in urban agglomeration commuter travel with intercity railway and city transfer mode,intercity bus and city transfer mode,car self-driving,parking transfer(P-R)as the selected object.From the point of view of commuter’s complete rationality,Use the income method to calculate the time value of different commuters,the characteristic factors of traffic mode affecting travel decision are quantitatively analyzed,the general cost function of different ways is constructed,and the choice model of commuter travel mode based on utility theory is constructed.From the perspective of commuter’s limited rationality,Take travel time cost,travel expense cost and comfort cost as the travel costs of the four types of travel modes,and their travel cost mathematical calculation formula is derived,according to the idea and principle of cumulative prospect theory(CPT),three types of travel cost are set up as reference points for commuter travel decision-making,and CPT-based urban agglomeration commuter mode choice model is established,The two models can obtain the optimal choice of each commuter mode under different rational conditions.Taking the commuters from Suzhou,Jia-shan and Taicang in the Yangtze River Delta city agglomeration as examples,the utility value and cumulative foreground value of different choice behaviors under the two models are calculated,the actual choice results are collected,Compare and analyze the theoretical selection results and actual selection results in different travel scenarios,and the validity of the empirical analysis model is empirically analyzed.Finally,this thesis studies the measures to improve the traffic of the intercity corridor,starting from the cost of travel,and puts forward the corresponding measures to increase the efficiency of the transportation system for intercity public transportation,cars and P-R,in order to provide reference for the formulation of traffic management policies and measures for urban agglomeration.
