I'm new here, I live in Toronto Canada. It's great that Open Street Map exists!
I've got a project in mind. Please let me know if this is happening already somewhere else...
Toronto is built to move cars around efficiently, but as more and more people switch to bicycles for various reasons, there is a need for efficient and safe bicycle route information.
I think the best way to create this resource is through a user generated bicycle route wiki. Users add their knowledge of good routes by sketching them on the map of the city.
I'm hoping this knowledge base will not only be used by cyclists but also by the City of Toronto Cycling Committee to help in planning and enlighten resource allocation debates.
