Research On The Choice Of Travel Mode In Historic District Considering Subjective Well-Being

With the rapid development of motorization,historical districts dominated by slow traffic are difficult to bear a large amount of traffic demand,and the service level of fast and slow traffic system is generally low.and affected by style protection,it is not easy to increase traffic supply to solve traffic problems,resulting in poor daily travel experience and quality of residents.Therefore,in order to pay attention to people’s spiritual needs,this paper introduces subjective well-being of travelers in historic districts into the traffic mode selection model,analyzes the choice mechanism of travel behavior and provides a theoretical basis for optimizing traffic space and traffic organization and management in historic districts.First of all,this paper designs a questionnaire based on travel characteristics,personal socio-economic attributes,travel subjective well-being including cognitive evaluation and emotional perception,and travel preference,and uses the method of RP and SP to obtain the effective sample data of single trip characteristics of travel groups in historic districts,and carries on the basic statistical analysis to the data.Secondly,based on the theory of structural equation model and disaggregate model,this paper proposes to construct a SEM-Logit integrated model of travel mode selection in historic districts considering subjective well-being.Finally,combined with the actual survey data,the SEM-Logit integration model is established to make an in-depth study on the traffic mode selection process,travel subjective well-being and its influencing factors of travel groups in historic districts,quantify the travel subjective well-being of different travel modes,and predict the results of different choices.At the same time,it puts forward the guiding policies and traffic management measures for the choice of travel modes in historic districts.The results of this paper show that,compared with the traditional Logit model,the SEM-Logit model considering subjective well-being is more suitable for the actual travel mode choice of historic districts,which verifies that the latent variables of travel subjective well-being including cognitive evaluation and emotional feelings have a significant impact on travelers’ travel behavior,and get the specific differences in travel subjective well-being among different traffic modes.In summary,the study helps relevant departments to understand the travel behavior and travel subjective well-being of different travel groups in historic districts,and provides a theoretical basis for further promoting the integrated development of the transportation system of cities and historic districts.
