My recent TEDxLongDock talk, Making Main Street a Shared Space, in which I goofed a few things:
I omitted the definition of a shared street:
short version: A pedestrian-priority street.
The slightly longer version: A shared street is a low-speed, typically curbless roadway designed as a single surface shared among pedestrians, bicyclists, and low-speed motor vehicles.
I listed some of the benefits but left out some important ones, including the fact that the street surface can be rethought in many ways, including mini-parks, places to sit and interact, and use of the shared surface for restaurants' tables and markets' goods, like flower and vegetable stands.
If you're interested read the manifesto, which is more detailed than the talk, and sign the manifesto to join the movement, and get on the mailing list.
