On the context of transportation planning, one travel behavior must be usually understood as a process including some decision makings. This paper describes discrete choice analysis of individual shopping travel behavior which consists of three dimensional travel decisions, i. e. shopping frequency, shopping destination and parking place choice. For empirical analysis, discrete choice models are applied, which are based upon random utility theory in microeconomics. We assume 3 level-nested structure for the decision makings and apply Nested Logit model and/or Ordered Logistic model, since the I. I. A. propetrty of logit model is not suitable for3dimensional travel decisions.The result of empirical analysis shows that the assumption of choice structure is statistically significant and O. L. model of frequency choice is very efficient. So, the relevant framework of travel behavior model is successfully developed. Finally, in order to represent validity and usefulenss of the model, some transportation polices are simulated and evaluated.
