Walkability refers to the accessibility of amenities by foot in urban spaces. It is based on the idea that urban spaces should be more than just transport corridors designed for maximum vehicle throughput, but rather relatively complete livable spaces that serve a variety of uses, users, and transportation modes and reduce the need for cars for travel. Walkable cities use planning, design, and density to maximize walking and minimize driving. The ability to allow a pedestrian-friendly space improves the livability of a city and supports the physical fitness of the city occupants.

Some key features of walkable cities include:

• Coherence: a clear, connected, and easy-to-navigate pedestrian network
• Density: a concentration of people and buildings
• Mix: a mix of different people and activities
• Access: a network of access routes that are safe and convenient for pedestrians

Walkable cities have many benefits, including improved air quality, reduced traffic congestion, and increased physical activity. They can also promote tourism and increase property values. However, there are still many obstacles that need to be cleared to achieve more complete and cohesive communities where residents wont have to travel as far to get to where they need to go.

Overall, walkability is an essential concept of sustainable urban design that considers people at the heart of the design and infrastructure.
