Junctions and crossings
We are currently revising and updating our detailed views on all aspects of cycling infrastructure and these will be published in due course. For general principles, please have a look at our 'overview' briefing on cycle-friendly design and planning.
The following is an extract from our Policy Handbook (March 2004):
- Features such as advanced stop lines (ASLs), priority approaches and special cycle phases should be incorporated at junctions.
- Signalled junctions are often preferable to roundabouts. However mini-roundabouts may be used as a speed control measure in traffic calming schemes and this may benefit cyclists.
- Increasing the entry deflection, narrowing the circulatory carriageway and providing circulatory lane markings can improve safety on roundabouts.
- Loop-detectors controlling traffic signals should be tuned to detect cyclists.
- All new schemes should be audited for cycle friendliness and as much of the existing transport network should be reviewed likewise.
- Subways and overbridges should be of high quality with good sightlines, sensible gradients, lighting and sufficient width. Converted footways are generally disliked by pedestrians and cyclists and should be avoided by transport planners. Low cost schemes to convert existing subways into shared use facilities are rarely satisfactory. Overbridges should be cycle friendly and not have steps.
- Toucan crossings are shared light controlled crossings. They allow cyclists and pedestrians to cross roads in safety, and are a good example of workable and cost effective facilities.
