A cycle track, separated bike lane or protected bike lane (sometimes historically referred to as a sidepath), is an exclusive bikeway that has elements of a separated path and on-road bike lane. A cycle track is located within or next to the roadway, but is made distinct from both the sidewalk and general purpose roadway by vertical barriers or elevation differences.
In urban planning, cycle tracks are designed to encourage bicycling in an effort to relieve automobile congestion and reduce pollution, reduce bicycling fatalities and injuries by eliminating the need for cars and bicycles to jockey for the same road space, and to reduce overall confusion and tension for all users of the road. In the United States, an academic analysis of eight cycle tracks found that they had increased bike traffic on the street by 75 percent within one year of installation. Rider surveys indicated that 10 percent of riders after installation would have chosen a different mode for that trip without the cycle track, and 25 percent said they were biking more in general since the installation of the cycle track.
Cycling infrastructure refers to all infrastructure which may be used by cyclists. This includes the same network of roads and streets used by motorists, except those roads from which cyclists have been banned (e.g., many freeways/motorways), plus additional bikeways that are not available to motor vehicles, such as bike paths, bike lanes, cycle tracks and, where permitted, sidewalks, plus amenities like bike racks for parking and specialized traffic signs and signals.
The manner in which the public road network is designed, built and managed can have a significant effect on the utility and safety of cycling. The cycling network may be able to provide the users with direct, convenient routes minimizing unnecessary delay and effort in reaching their destinations. Settlements with a dense road network of interconnected streets tend to be viable utility cycling environments.
A bikeway is a lane, route, way or path which in some manner is specifically designed and /or designated for bicycle travel. Bike lanes demarcated by a painted marking are quite common in many cities. Cycle tracks demarcated by barriers, bollards or boulevards are quite common in some European countries such as the Netherlands, Denmark and Germany. They are also increasingly common in other major cities such as New York City, Melbourne, Ottawa, Vancouver and San Francisco. Montreal and Davis, California, which have had segregated cycling facilities with barriers for several decades, are among the earliest examples in North American cities.
