Structural Equation Modeling of Desired Travel Amounts
| 项目名称： | Structural Equation Modeling of Desired Travel Amounts |
| 摘要： | Why do some individuals want to travel more, and others less? Just asking this question is novel, as most transportation researchers consider travel to be strictly a cost necessary to participate in spatially-separated activities. That premise is challenged here in a "first principles" examination of travel behavior. Four key travel-related constructs are defined: Objective Mobility, Subjective Mobility, Travel Liking, and Relative Desired Mobility. A 1998 survey measured these variables for travel segmented by length, purpose, and mode, as well as attitudes, personality, lifestyle, and socio-demographics, for more than 1,300 workers in the San Francisco Bay Area. Prior analysis of this dataset has involved only single-equation models, and has exposed considerable endogeneity among the four key constructs. Here, structural equation modeling will be used to sort out the inter-relation¬ships among these endogenous variables, as well as other relationships present in the dataset. The findings will have important implications for our understanding and prediction of travel behavior. |
