Advanced Stop Lines (ASLs)

Advanced stop lines are an excellent way of giving cyclists visible priority at junctions, where around 70% of cyclists' collisions occur. Good design is crucial, of course.
ASLs help cyclists at junctions
Headline Messages: 
  • Advanced Stop Lines (ASLs, also known as cycle boxes) are some of the cheapest, most cost-effective and popular ways to give cyclists visible priority at junctions, where around 70% of cyclists’ collisions occur. They help cyclists control their own safety as they prepare to manoeuvre through the junction, by positioning themselves where they are clearly visible to the drivers behind them.
  • ASLs should be progressively introduced on all traffic-light junction arms, with possible exceptions for busy high-speed roads with high quality off-road cycle facilities. Decent width ‘feeder lanes’ should enable cyclists to reach the ASLs without being obstructed by queuing traffic.  In some situations, it is beneficial to provide a feeder lane between or to the right of the general traffic lanes, either instead of or in addition to one on the left hand side, or to provide no feeder lane at all. Cyclists should be warned not to use left-hand side feeder lanes to undertake lorries, although we know of no evidence to date that providing these lanes increases the risks of collisions with left-turning motor vehicles.
  • CTC recommends the progressive introduction of coloured surfacing for ASLs and their feeder lanes, focusing particularly on those junctions where cyclists most need to assert their priority to avoid being cut up.
CTC View (formal statement of CTC's policy): 
  • There should be a presumption in favour of providing Advanced Stop Lines (ASLs) on all arms of all signalised junctions.
  • Highway authorities should progressively introduce ASLs at all signalised junctions, making site-specific alterations to the junction layout as required. Exceptions may be made on high speed (40mph or above) where there are existing off-carriageway facilities that meet cyclists’ needs, or where a decision is taken to provide these.
  • The Government should pursue moves to clarify and amend the legislation covering cyclists’ access to and use of ASLs; and make civil enforcement of ASLs possible.
  • Each location needs to be carefully assessed to determine the most appropriate site specific layout, having regard for the line of approach taken by cyclists and their turning movements. The safety benefits of different ASL layouts should be kept under review.
  • ASLs should be provided with at least one feeder lane on any junction arm where the traffic volumes and speeds merit the provision of a cycle lane (or cycle use of a bus lane), in accordance with CTC’s campaigns briefing on on-road cycling (forthcoming).
  • On any junction arm with more than one entry lane, consideration should be given to providing a feeder lane away from the kerb (i.e. either between or to the right of the general traffic lanes).  This may be either in addition to or instead of a feeder lane to the left of the general traffic lanes. The safety benefits of different ASL layouts should be kept under review.
  • Feeder lanes should be at least 1.5m wide, preferably 2m, especially where cycle flows are high. General traffic lanes on junction approaches can be reduced to 2.5m to accommodate this, and 2.25m is acceptable on quieter streets with little or no bus or lorry traffic.
  • CTC recommends the progressive introduction of coloured surfacing for ASLs and their feeder lanes. Priority should be given to locations with multiple general traffic lanes and/or complex conflicting movements between cyclists and motorised traffic.

Vegetation and hedge trimmings

Cyclists have problems with overhanging vegetation or hedge trimmings left on the routes they use. Debris can cause punctures or even serious injury if it gets caught in wheels...
Mending a puncture
Headline Messages: 
  • Cyclists encounter problems if vegetation along the routes they use is not well trimmed. Overgrown branches can obscure visibility or get in the way, for instance.
  • Cyclists also suffer when debris is left strewn about following careless or incompetent hedge trimming practices. 
  • Debris has the potential to cause punctures or – worse – it may get caught in wheels sometimes with serious, even fatal, consequences.
CTC View (formal statement of CTC's policy): 
  • Those responsible for trimming vegetation should do so regularly and in accordance with best practice
  • Local authorities and the police should actively pursue and, as necessary, prosecute offenders
  • Overhanging vegetation and debris along routes used by cyclists, both on and off-road, should be regularly and attentively cleared.

London's Cycle Hire least used and most expensive in Europe

Comparative data from various international bike share schemes show that London's cycle hire scheme is one of the least used and is the most expensive public scheme to operate. The lack of a cycle network in central London is likely to be the main reason why usage is so much lower.
London's scheme is used half as much as Paris's

Whereas each bike in Barcelona's scheme is used over 10 times per day, London's are used just 3 times.

'Boris Bikes' are used less than half as often as the Parisian Velib' scheme.

The study, undertaken by US-based sustainable transport think tank ITDP, explored data from four of the biggest schemes in Europe and a range of north and south American schemes, and made recommendations for how to run an effective bike share scheme.

Boris must stop ducking responsibility for action to save lives

CTC's Campaigns Director Roger Geffen argues that Boris's "finger-pointing" is pointed in the wrong direction, and calls for real solutions to the dangers faced by pedestrians as well as cyclists.

There has been a truly appalling death-toll on London’s roads in the past 13 days.  Prior to November 5th, there had been 8 cyclist fatalities in 10 months this year.  Since then, we have 6 cyclists’ and 3 pedestrians’ deaths within 13 days, all killed by lorries, coaches or buses.  In total, 9 of the 14 fatalities this year have involved lorries.

Government predicts cycling will FALL by 2040

While the Get Britain Cycling report calls on Government to aim for 10% of trips by 2025 and 25% of trips by 2050, in the bowels of the Department for Transport, technicians working on the National Transport Model are forecasting that cycling will fall for decades to come.

Traffic modelling - the act of forecasting how much additional traffic there will be in future - is a dark art.

Forecasting is tricky: feedback loops and unknown future changes can rapidly upset any firm conclusions about current trajectories.

Road safety procession to be held on Sat 21st in Birmingham in Hope Fennell's name

This week Hope Fennell would have turned 15 had her short life not been tragically ended in 2011. A procession calling for improved road safety will be held in her name on Saturday 21 September in Birmingham.
13-year-old Hope Fennell was killed whilst crossing a pedestrian crossing

Hope was killed by a lorry as she pushed her bike across a pedestrian crossing in Kings Heath, Birmingham in November 2011. The driver of the lorry, Darren Foster, moved his vehicle off when the lights turned green not knowing that at that moment Hope was in front of the vehicle. Hope died trapped under the lorry’s wheels.

Why the Cyclist's Defence Fund is supporting one cyclist’s challenge of a FPN

A few weeks ago, Alex Paxton was issued with a fixed penalty notice (FPN) for failing to stop at a red light, yet all he was doing was positioning himself in front of a car which had illegally occupied the advanced stop box.
ASLs are good for cyclists, but could be better

Alex had intended to position himself in the cyclists’ box in order to turn right, but found that the box had been illegally occupied by a motorist. With concern for his own safety were he to stay in the inside lane and then have to cross three lanes of moving traffic in order to turn right, he decided to position himself ahead of the traffic and ahead of the Advanced Stop Line (ASL).

100 MPs reach a consensus on cycling

Around 100 MPs from all political parties attended a packed backbench business debate on cycling for 4 hours on Monday evening, with dozens of MPs taking part.
MPs debated cycling for 4 hours

The debate ended with an unopposed vote in favour of the motion "That this House supports the recommendations of the All-Party Parliamentary Cycling Group's report ‘Get Britain Cycling’; endorses the target of 10 per cent of all journeys being made by bike by 2025, and 25 per cent by 2050; and calls on the Government to show strong political leadership, including an annual Cycling Action Plan and sustained funding for cycling."

Cycle infrastructure trials could finally mean good cycle tracks are built

In June CTC was invited, along with many others from the cycling world, to see first hand the trials being conducted by TRL (formerly the Transport Research Laboratory) of various measures to enhance safety and provision for cycling.

My comment in the Guardian article on the subject seemed to disparage the idea. 

Actually, CTC is extremely supportive of the idea of improving the design of infrastructure along Dutch principles.
