Cycle lanes are the painted lines, usually to the edge of the road, designed to give cyclists dedicated space on streets.
They can help cyclists bypass queuing motor traffic and are routinely provided as lead-in lanes to Advanced Stop Line (ASL) boxes at traffic lights.
However, their effectiveness is disputed, as they imply cyclist should be positioned to the kerbside of streets, not in the primary position advocated by Bikeability and other contemporary cycle training course.
It is widely recognised that there are much more important measures to be undertaken to reduce road danger cycling, such as junction improvements.
Whenever cycle lanes are implemented, they should be at least 2 metres wide.
Cycle tracks and cycle paths are routes on designated space physically separated from motor traffic, either beside a road or though parkland.
They can provide the least stressful cycling experience, and provide a high degree of subjective safety, where the cyclist feels safe.
Too often in London these are implemented poorly, with broken sections of track, losing priority at junctions and entrances to premises, and using narrow lanes unsuitable for cyclists overtaking or large volumes of cycle traffic.
We support the implementation of cycle tracks when speeds and volumes of motor traffic are high, on streets such as Old Kent Road or the Embankment.
Segregated tracks can persuade Londoners to cycle on busy streets. We'll continue to call for other measures such as removing through traffic and speed reductions on local streets.
We welcomed the Superhighways project to build fast commuter routes from outer to inner London. However, like many others, we were underwhelmed by the first two pilots Superhighways.
We've offered the mayor detailed advice as to how the routes could truly encourage more novice cyclists, but not enough of our recommendations have been adopted.
More one-way systems and big junctions must be made more cycle-friendly, and the prioritising of the car to the detriment of the routes must stop.
We'll continue to work with the Superhighways team in the hope that they will deliver meaningful improvements.
Cycle Hire scheme
We proposed a mass Cycle Hire scheme for London in 2007, and were delighted when the current infrastructure was opened in 2010.
The scheme has been a great success, despite some early technology problems, and we welcome the appearance of docking stations on thousands of street corners, pushing the profile of cycling higher into the city's consciousness.
We welcome the expansion eastwards, and will be pushing for docking stations to be rolled out further across Greater London, particularly south of the river.
