A carfree city is a population center that relies primarily on public transport, walking, or cycling for transport within the urban area. Districts where motorized vehicles are prohibited are referred to as carfree zones. Carfree city models have gained traction due to current issues with congestion and infrastructure, and proposed environmental and quality of life benefits. Currently in Asia, Europe and Africa, many cities continued to have carfree areas due to inception before the origin of the automobile. Many developing cities in Asia are currently using the proposed model to modernize its infrastructure.
