Open streets initiatives temporarily close streets to automobile traffic, so that people may use them for just about any activity but driving. As of early 2012, there are more than 70 known initiatives in the North America. In February 2012 the Open Streets Project published a comprehensive guide which includes an introduction to open streets, best practices, 67 case studies and links to further resources.

The Open Streets Project was formed to share information about open streets and increase the number, size, and frequency of initiatives occurring across North America. The open streets movement has grown from 11 initiatives in 2005 to more than 70 in 2012.
