But some metros are making their streets more walkable and creating easier ways for residents to bike or take public transit instead of driving. For example, the Miami neighborhood of Wynwood recently transformed itself into a walkable district - complete with cafes, art galleries, and restaurants - by adding car-free zones. Last year, Boston announced a plan to become the most walkable city in the US by 2030 by making sure every home is within a 10-minute walk of a subway station or bus stop.
Walk Score, a company that analyzes car-free efforts in urban areas, recently released its annual ranking of walkable US cities. The list compares metros with populations that range from 200,000 to 10 million, and measures how easily residents can accomplish errands on foot, by bike, or using public transit.
While it's still difficult to live in most American cities without a vehicle, Walk Score's metric clarifies which places may be the least car-dependent.
