Study On The Influence Of The TDM Policies On Urban Transportation Structure

With the traffic problems become more and more serious, balance the urban traffic structure is one of the keys of the transportation problem. The urban traffic structure referred to the paper is the urban transportation trip structure which is reflected by the passenger traffic mode choosing and impacted by the transportation policy formulation and implementation. Therefore, it is has a great theoretical and practical significance to study the influence of transport policies on balancing the urban traffic structure and establish appropriate mode choice model.In the paper, the method of qualitative and quantitative analysis is combined. The status quo of urban passenger traffic structure and the influent factors of the residents' choice for trip mode were analyzed. Focused on the relationships between the urban transport policies, traffic structure and residents' mode choice, the influence of transportation demand management (TDM) on traffic structure was discussed. Based on the theory of disaggregating modeling, ML model was established with the policy factor joined as a variable, and the parameters were calibrated by SPSS Multinomial Logistic Regression. Against the research background of Beijing Olympic Comprehensive Test, data from normal and TDM implementing days surveys was analyzed and contrasted to conclude that the residents mode choose will be changed under the different measures implementation.Research shows that the disaggregate model which is more feasible and practical could reflect the implementation for transportation demand management policy well from a microcosmic. TDM policy can achieve the goal of residents' travel behavior adjustment and finally optimize the urban passenger transport structure. It will become the most important reference for policy formulation and development trends for future cities, especially the developing cities.
