Car ownership in households The transport patterns and modal splits are strongly influenced by a decision of households of how many cars to own. The number of available cars in the household determines the public transport usage and effectiveness of transport investment policies. The thesis aims to explore the reasons that determine the decision to own 0, 1, 2, 3, or more cars. The method of the thesis will be a consumer survey among households. The survey will investigate the socio-economic characteristics of households and attitudes of their members toward cars and public transport. Based on this survey the multinominal logit model will be estimated and the determinants of choice identified.
