Walkability is a term for planning concepts best understood by the mixed-use of amenities in high-density neighborhoods where people can access said amenities by foot. It is based on the idea that urban spaces should be more than just transport corridors designed for maximum vehicle throughput. Instead, it should be relatively complete livable spaces that serve a variety of uses, users, and transportation modes and reduce the need for cars for travel.

The term "walkability" was primarily invented in the 1960s due to Jane Jacobs' revolution in urban studies. In recent years, walkability has become popular because of its health, economic, and environmental benefits. It is an essential concept of sustainable urban design. Factors influencing walkability include the presence or absence and quality of footpaths, sidewalks or other pedestrian rights-of-way, traffic and road conditions, land use patterns, building accessibility, and safety, among others.
