New York City is one of the only cities in America where it is practical to travel on foot. While automibles have taken over many other places, New York City still has sidewalks. And these sidewalks are more than just one of the city's most definable landmarks. They are vital public spaces that strengthen communities. New York City Streets Renaissance, a campaign founded by the Open Planning Project, Transportation Alternatives and Project for Public Spaces, seeks to respond to concerns that New York City is putting cars before people.The project's exhibition at the Urban Center Gallery, "Livable Streets," features multimedia, images and graphics exploring ways that city planners can design for people. "If we design streets for cars and traffic we will get more cars and traffic; conversely if we start planning our cities for people and places, we will get more people and places," it says. The exhibition will be at the Urban Center Gallery at 457 Madison Avenue (near East 51st Street) until March 29.
