Cycling Super Highways
Rachel Smith suggests a two-tiered structure of cycling super highways. The first tier is within a five kilometre radius of a target area such as a central business district or a transport hub. Based on research she has done in places where there is high cycling participation, she suggests cycle ways 7.7 metres wide, with additional space for pedestrian traffic if required. Within 5km and 10km she suggests a four metre width.
The presentation contains a brief description of about twenty localities, mainly in Europe, and demonstrates their approach to cycling. A sample:
Bogota now has a 5% cycling participation (up from 0.5% before Penalosa got going). In Copenhagen every new cycle track results in 10% less cars on that segment (and 20% more cyclists). In Delft the bicycle mode share is 43% vs public transport 4%. The small city of Groeningen has a 57% cycling participation rate. The Federal Highway Administration in the USA found that separated bike paths are perceived by the public to be the safest bikeway facility. They built a 32km bike only path in Santa Monica. The Muenster train station has parking for 3300 bikes. Odense has 3 metres of bike paths per person (for Perth that would mean a 3000km network). The introduction of Velib in Paris has dropped private car use by 20%.
I found her well-documented presentation on this share site. A warning – it is about 14 mb.
