Our options for getting around depend very much on where we live. Choosing where you live for its convenience of walking or biking to work, school, or transit—what planners call location efficiency—is a key way to reduce your need for driving. In some areas, people find it surprisingly easy to do without a car at all. The more you know about the decision-making process of these efficiencies, the more likely we are to have access to personal transportation options that are safe, efficient, and responsive to public needs and concerns about their communities and the natural environment.
