Following on from my previous post, this is another 'knock these ideas around' kind of post. Going to list what I think are the parameters for safe, effective cycle routes. I'll update this as other suggestions come, and I'll add other posts for maintenance, enforcement, etc.
The purpose of cycle lanes is to:
1. Create a safe space for all cyclists to use.
2. Encourage a greater uptake of cycling in the UK, with a target being 50% modal share of journeys being by bicycle.
3. Be both pleasant and convenient to ride on - facilities must be attractive to novices and experienced cyclists alike.
To achieve this, we must consider many factors; I propose that we set 'gold' standards for cycle facilities and judge them based upon whether they meat this standard.
The 'gold' standard for cycle infrastructure should aspire to includes:
1. On all busy routes, fully segregated facilities where cyclists are protected from motorised vehicles without creating a threat to pedestrians.
2. Sufficient width in either direction to allow safe overtaking.
3. A surface appropriate for comfortable riding up to 30mph
4. Priority over side roads equal to that of the road the route runs parallel to, i.e. if the route runs alongside a road which has priority over a side road or driveway, then the cycle lane must also have priority.
(a) This must be enforced with signage, route design, or clear lane markings
(b) This must be labelled with 'give way' signs reinforce cyclists priority.
5. All routes must be continuous - cycle routes which disappear as road space becomes more pressing are of no value to cyclists.
6. Smart segregation at junctions, including:
(a) Cycle friendly roundabout design
(b) Advance stop positions for cyclists and advance light changes where full segregation not possible
7. Clear labelling of cycle facilities, including
(a) Coloured road surfaces to ensure cyclist and pedestrian safety
(b) Clear indication that motorised vehicles not be in cycle facilities
8. Engineered solutions to keep cars and other motorised vehicles from parking in cycle lanes
9. 'Strategic' inclusion of all cycle routes to create a network of safe, pleasant, and real life journey types
10. Corners on cycle routes must be engineered such that they are legally and safely navigable by cyclists of varying skill levels - extreme angles must be avoided except where unavoidable.
