There are significant deviations in travel mode choice drivers between developed and developing countries. This study investigates the determinants of car ownership and public transit ridership in Iran. Using survey data from 800 respondents, the determinants of travel behaviour of Kerman residents were investigated, based on gender, age, household size, car ownership, frequency of public transport ridership, number of working days per week, number of shopping activities in the neighbourhood per week, number of entertainment activities in the neighbourhood per week, and number of shopping activities in the city. Two multivariate models were estimated using the OLS and WLS methods. Our findings suggested that owning a car tends to increase as age, household size, number of working days and number of shopping days in the city decreases. An increase in the number of entertainment days in the neighbourhood raised the probability of car ownership while shopping in the neighbourhood did not influence car ownership. Public transport use was negatively influenced by gender, increased age and number of working days, but positively influenced by shopping in the city. Our research results have significant implications for transport planning. Firstly, changes in household size may not be a good basis to inform planning as our findings show that in Kerman as household size increases, car ownership decreases, and it does not influence public transport. Secondly, when planning road network connectivity (land use) higher working days are expected to increase both car ownership and public transport use.
