The National Association of City Transportation Officials (NACTO) has created "Cities for Cycling". The goal is to to catalog, promote and implement the world's best bicycle transportation practices in American municipalities. They take inspiration from the most bike-friendly cities in the US and around the world and try to package that information in a way that is easy to use for the urban planners and engineers of other cities that might not have much experience building quality bike infrastructure.
"Cities for Cycling and NACTO seeks to create a comprehensive Urban Bikeway Design Guide which will have two major final products: a web-based version that includes a platform for discussion and information exchange, and a printed summary that will be updated regularly."
No Need to Reinvent the Wheel
I think it's a fantastic idea! Why re-invent the wheel and wait for every city to figure out how to best accomodate cyclist via trial-and-error? We don't have that much time. It's best to all work together to expedite the process and learn from each other.
The same thing should be done in all kinds of areas: Sharing best-practices on green roofs, public transit, walkable neighborhood, etc.
Our friends at Streetfilms attended the recent NACTO meeting in Boston and documented what happened. Check it out, it's great:
