Built environments include the layout and design of communities in which people live and work. Research demonstrates that built environments that create physical activity opportunities for people of all ages and abilities, and that also support various types of transportation, are essential in supporting physical activity. A well-designed built environment may include elements such as sidewalks that are wide enough for people in wheelchairs, rest stops, safety features and greenery.
