"Cycle tracks, notes Lusk, are actually a separated part of the roadway yet distinct from the roadway, distinct from the sidewalk. In their purest form -- Odense, Denmark, where 50 percent of all city journeys are by bicycle -- the paths even have their own traffic signals.
What actually separates the cycle track? It can be a long, narrow curb. Or a line of cones or concrete barriers. Or metal stanchions. Or a line of trees and other vegetation (an on-street greenway).
Another solution, tried on relatively wide streets in Bogota, Paris, London and elsewhere, is to move the parking lane several feet from the sidewalk, creating a new lane for cyclists between the sidewalk and parked cars. Brooklyn-based bicycle advocate/blogger Aaron Naparstek has an excellent online video celebrating that solution (www.streetfilms.org/archives/physically-separated-bike-lanes/)."
