Taking a cue from Shakespeare, this video examines the role of social interaction in active transportation. Emphasizing that the experience of the bicyclist has been overlooked, this video portrays the aspects related to social interaction when it comes to people on bikes. People on foot do not experience urbis the same that people on bikes do. This video takes one theory of spatial proximity for humans as a way to describe the social space of people on bikes. Then, reviews experiences of people on bikes in Portland, Copenhagen, and Seattle to see how the built environment functions to support or deny this social space.
