Dependence on cars in urban neighbourhoods

In this article, we focus on the relationship between the types of neighbourhoods in which people live and the use of cars for daily travel.

To what extent can residents of central neighbourhoods go about their day-to-day business without necessarily using a car? In which metropolitan areas is exclusive use of the automobile most common?
