| With the continuous improvement of urbanization and motorization level,the traditional single-center urban traffic problem has become increasingly prominent.The group-type layout can effectively reduce the traffic pressure in the central area by dispersing the traffic flow among various groups,which has gradually become the main development trend of the expansion of large cities in China.For group cities,the traffic channel between groups is the "aorta" of group cities,which largely determines the operation efficiency and quality of life of group cities.To ensure the orderly and unobstructed traffic of the traffic channel between groups is the key to the sustainable development of group cities.It is of great significance to optimize the travel structure of inter-group transportation and promote the development and construction of inter-group cities to master the decision-making method of residents’ travel mode choice in inter-group transportation.In this paper,travelers in the inter-group traffic passage are taken as the research object.First,the content and scope of the research are determined by analyzing the travel process,travel characteristics and travel mode composition of the inter-group traffic passage.Secondly,based on the connotation and process of residents’ choice of travel modes,this paper analyzes the factors that influence residents’ choice of travel modes in inter-group traffic passageways from both macro and micro levels,and explains the bounded rationality of residents’ choice of travel modes in inter-group traffic passageways.Next,in view of the city group communication channel between urban residents travel mode choice for a typical hybrid stochastic multi-attribute decision-making behavior,give a way to travel decision-making method based on cumulative prospect theory and method of economy,quickness,comfort,convenience,reliability and safety for group communication channel between traveler mode decision index and attribute;Considering that the attribute value information is a mixture of grey random variable and linguistic variable,a method to normalize the attribute value to the interval [0,1] is given.When setting the reference point,the heterogeneity of travelers and the psychological behavior that travelers have dynamic expectation requirements on the attributes of various decision indicators at different travel stages are fully taken into account.After travelers are classified according to their travel purposes and income levels,the expected value of travelers on the attributes of various indicators at different travel stages is taken as the reference point.,through calculating mode attribute value and the distance of the reference point of decision matrix can be converted to reference point of profit loss in different stages of the decision matrix,according to the decision makers risk attitude to different stages of gains and losses,assembled prospects of different properties and different stages of value to determine the comprehensive prospect value of each way,and to build the value of utility value Logit group communication channel between residents travel mode choice model.Finally,taking the traffic passage from chongqing nanping group to yuzhong group as an example,and combining the SP and RP survey methods,the travelers were investigated with the questionnaire on the choice of travel mode,and the survey data were brought into the model established in this paper,and calculated with the help of MATLAB programming.The comparison between the calculated results and the actual survey results shows that the two are basically in agreement,which indicates that this paper constructs an effective and scientific model for residents’ choice of travel mode in the inter-group traffic passage. |
