Bicycle streets

What is the definition of a bicycle street? (“Fietsstraat” in Dutch, or ‘bicycle boulevard’ as they are mostly called in the US.) Nowadays a bicycle street is considered to be a route in a residential area that is a main route for cycling, but only a minor route for motor traffic. It is essential that cycle traffic is the dominating form of traffic and that the route looks clearly designed for cycling. This makes it immediately clear to drivers of a motor vehicle that they are guest in a space that is not theirs. (CROW recommendation in publication 216) Note, that we are talking about a route rather than a street. The Dutch always construct cycle routes, never individual streets, even if they call those routes ‘street’. Parking motor vehicles in a cycle street is also possible. The word cycle street does not imply that there are no cars. There are, parked and moving, but they are the minority form of transport. That the streets are in a residential area automatically means that the speed limit for motor traffic is 30km/h. (With the exception of rural cycle roads where that would be 60km/h.) Read more here.
