“…Gender was found as an important factor that may influence consumers' vehicle demand (Ede and Panigrahi, 2000;Choo and Mokhtarian, 2004;Sen, 2006, Cao et al, 2006;Prieto and Caemmerer, 2013;Sanko et al, 2014). Household size can be an important explanatory variable in examining consumers' purchase behaviour and many early studies (Choo and Mokhtarian, 2004;Kumar and Krishna Rao, 2006;Potoglou, 2008;Potoglou and Kanaroglou, 2008a;Bhat et al, 2009;Prieto and Caemmerer, 2013;Wong, 2013;Sanko et al, 2014) found significant association between household size and vehicle type ownership. There has been recent work in which respondents' educational level was demonstrated as the significant contributor to consumers' vehicle ownership (Ede and Panigrahi, 2000;Yılmaz, 2001;Choo and Mokhtarian, 2004;Cao et al, 2006;Potoglou, 2008;Hackbarth and Madlener, 2013;Prieto and Caemmerer, 2013).…”
