Rising private vehicles use has given rise to many negative impacts on the global environment. This paper reviewed three main factors and their effects on the growth of vehicle ownership for countries with different economic levels based on a total of 60 studies published between 1997 and 2021. Income level was the most important factor alongside other socio-economic and demographic factors such as population density, household size, household employment, education level, age distribution and gender distribution. Factors related to urban developments include urbanization, road infrastructure, public transport and availability of parking space. Besides economic growth, this review also explains the effects of income inequality and road infrastructure development on the choice of using private vehicle. The findings reviewed in this paper sheds light on many of the underlying relationships among the factors that were found significant in explaining the variation of private mobility patterns from the global perspective. Several research gaps were also highlighted based on the findings.
