Uni-Directional Protected Lanes

BOOKMARK

One-way protected bike lanes are at street level and use a variety of methods for physical protection from passing traffic. One-way protected bike lanes may be incorporated into a previous parking lane or other parallel lane, complete with a protective barrier between the bike lane and the motor vehicle travel lane. When a cycle track is elevated above street level, it is called a raised cycle track and different design considerations may apply.

Uni-directional protected lanes have a standard width of 2.2 meters, with 1.7 meters as the bare minimum. Where an adjacent parking lane doesn’t exist, however, the width may go as low as 1.5 meters, but only on low-traffic, low speed streets.
