Abstract: Under the consideration of land use,based on the structural equation model,using the data of Chengdu traffic travel survey,the authors selected the travel behavior as endogenous latent variables,the travel distance,travel time and travel times as endogenous variables;and selected land-use social economic attributes and household attributes as exogenous latent variables,and the land use zone type,occupation,gender,age and other factors as exogenous variables;by taking the individual traveler under the household attributes as the unit for analysis,by considering the personal and family socio-economic attributes,quantitatively quantified the complex relationship among different variables.This paper is practical to the design of travel survey,the analysis of travel behavior and the traffic demand model,and it provides a quantitative analysis to the comprehensive transportation planning decision.
