cardependent

Car-dependent describes urban or regional patterns in which private automobile travel is the primary means of moving residents for most daily activities, due to land-use arrangements and infrastructure that discourage or impede walking, cycling, and public transit.

Common characteristics include low residential density, separation of homes, workplaces, shops, and services by large distances; widespread single-use zoning; extensive road networks designed primarily for cars; abundant parking; and limited safe, convenient sidewalks, bike lanes, and frequent transit stops. Travel times in car-dependent areas often favor driving, and destinations may be difficult to reach without a car.

These patterns often arise from postwar suburban expansion, highway construction, and zoning policies that promote automobile access and single-use development. In some regions, rapid motorization and affordable vehicles reinforce dependence on cars. Car-dependent areas are frequently found in outer suburbs of large cities, peri-urban zones, and in parts of developing countries undergoing urban growth and infrastructure investment.

Impacts of car-dependence include higher vehicle miles traveled, traffic congestion, greenhouse gas emissions, air and noise pollution, and higher transportation costs for households. Accessibility can become limited for non-drivers—such as children, the elderly, and low-income residents—often exacerbating social and health inequities due to reduced opportunities for walking and physical activity.

Mitigation and planning responses emphasize reducing dependence through increased density and mixed-use development near transit, complete streets that accommodate pedestrians, cyclists, and transit, expanded and improved public transit networks, enhanced non-motorized infrastructure, and parking management and demand-reduction strategies.
