  3. Abstract:
  4. In this paper, a disaggregate model is developed for household car ownership based on a data set from the city of Mashad. The approach adopted in this study is a two-level nested logit in which conditional probability of owning one car vs two or more is modeled at level 1, then marginal probability of owning a car is modeled at level 2. Seven groups of descriptive variables, each including one or more variables divided into two separate classes for each level, were employed in the model building process. Household demographics and socio-economic indicators, including head of the household characteristics like gender, age and occupation, as well as life style and life cycle stage, were among the variables which showed significant effects on car ownership. Results demonstrate the appropriateness of the nested logit structure and reject the application of the simple multinomial logit models when the IIA property is not valid. Necessity of data sets with rich information, more appropriate for disaggregate modeling applications, is further recommended
