Walkability is the crucial first step in ensuring safe, equitable access to all and creating sustainable and inclusive cities and urban mobility and transportation systems. All trips require walking at some part of the trip, and it has the lowest barrier to entry of all transportation modes, enabling access for poor and rich, men and women, young and old, and all ethnic and minority groups alike, while supporting other sustainable transportation modes such as public transportation and cycling. Safe pedestrian amenities are also usually safer for people with physical disabilities. Walking generates no pollution and walkable communities usually have better mental and physical health, contributing to become stronger communities. By building compact walkable communities, societies can reduce infrastructure costs immensely, enabling public money to support other social services such as access to education and health care. Residents of compact walkable communities spend less time and money traveling, increasing their ability to improve their lives. Walkable communities are more resilient.
