The Effectiveness of Private Motorized Trips Indicators in Reducing Car Usage

Neighborhoods with similar design may have different travel behavior due to the impacts of socio-economic indicators. There are also some effective indicators such as residents’ income, age, and self-selection factors related to this case that cannot be evaluated easily, which question the reliability of previous efforts to describe the effects of private motorized trips indicators on car usage universally. On the other hand, private motorized trips indicators are effective factors that influence travel behavior but these indicators have not been evaluated in considerable studies. This paper introduces a multiple-linear regression analysis to estimate the relationship of private motorized trips indicators and car usage in various cities in different parts of the world with various socio-economic contexts. So, the results of this study are reliable enough to illustrate this relationship with international scale. The significant private motorized trips factors are also identified in this research for being utilized in car reduction strategies in urban areas.
