Traditionally, economists and market researchers have been interested in identifying the factors that affect consumers' car buying behaviors, and have developed various models of vehicle type choice to estimate market share. However, they do not usually consider consumers' travel attitudes, personality, lifestyle, and mobility as factors that may affect the vehicle type choice. The purpose of this research is to explore the travel attitude, personality, lifestyle, and mobility factors that affect individuals' vehicle type choices, and to develop a disaggregate choice model of vehicle type based on these factors as well as typical demographic variables. We first discuss key literature related to vehicle type choice models, vehicle use models, and mobility, and then describe the characteristics of our sample, the vehicle classification we used in this study, and key explanatory variables included in the vehicle type choice model. The relationships of vehicle type to travel attitude, personality, lifestyle, mobility, and demographic variables are individually explored using one-way ANOVA and chi-squared tests, and then a multinomial logit model for vehicle type choice is developed.
