A cycle track can be next to a normal road, and can either be a shared route with pedestrians (common in countries such as the United Kingdom) or be made distinct from both the pavement and general roadway by vertical barriers or elevation differences.
When located alongside normal roads, they usually have some separation from motor traffic in the form of bollards, car parking, barriers or boulevards.
[3] Barriers may include curbs, concrete berms, posts, planting/median strips, walls, trenches, or fences.
[5] 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.
Studies generally show an increase in collisions at junctions, especially where cyclists are travelling in the direction opposite to the flow of traffic (e.g. on two-way cycle tracks).
LTN 1/20 states that one-way cycle tracks should be a minimum of 1.5-2.5 metres depending on the number of cyclists.
