Identifying the Characteristics of Households with Multiple Car Ownership

This paper examines the characteristics of households with multiple car ownership in\nDublin, Ireland. Data from the 2006 Census of Ireland are analysed to ascertain the\ncharacteristics of these households. The analysis of multiple car ownership presented\nherein examines individual specific, transport availability, and household\ncharacteristics to provide an indication of the individuals most likely to have access to\nmore than one vehicle. The analysis of multiple car ownership presented in this paper\nexamines both individual specific characteristics and household characteristics to\nprovide an indication of the individuals most likely to have access to more than one\nvehicle. Understanding the characteristics of households with more than one car is\nimportant for many reasons. Ireland, like many countries has recently launched a\nnumber of electric vehicle and car sharing schemes. Traditionally these schemes have\nbeen aimed at reducing multiple car ownership, therefore it’s important to develop an\nunderstanding of the households that would most likely give up an extra car and use a\ncar club or an electric vehicle.\nThe results of this paper show that several factors impact upon multiple car\nownership. Factors such as occupation, residential density, household structure, and\npublic transport availability all have significant impacts upon the decision to own\nmore than one car. The findings of the multinomial logistic regression modelling are\napplied to find an area in Dublin that has high potential for either changing the\nhouseholds’ second or third vehicle to an electric car or the use of a car club.
