Structural equation model analysis of travel mode choice for urban residents

To overcome the limitation of Logit model,this paper developed a structural equation model for travel mode choice in the process of rapid urbanization based on the analysis unit of 'trip chain'.Firstly,three kinds of influence factor were determined according to the traveler's characteristics in rapid urbanization,and some hypotheses were advanced to describe the relationship between influence factors and travel mode choice.Then,the structural equation model was constructed.Using the travel survey data of Beijing,the model was computed and modified.The model computing result shows the quantitative relationships among traveler characteristics,land use,trip chain and travel mode choice.These findings have important implications for travel mode optimization and for the ease of traffic congestion.
