Cycle-specific traffic lights coming to Blackfriars Bridge: Transport for London drops another big hint new road layout on its way

Late last week, Transport for London opened its new 'bicycle-friendlier' junction at Bow roundabout. The solution is (unbelievably) quite radical for London - a segregated bike lane approaches the junction and people on bikes get a (slightly) separate traffic light phase.

In any other country, Transport for London would be able to make use of dedicated bicycle traffic lights and bicycle traffic phasing all over London. But not in the UK. As TfL puts it in a comment to The Times: "the new design incorporates the full extent of what can be installed 'within current Department for Transport regulations'".

For once, I'm not going to knock Transport for London about this. Instead, I'm going to knock the Department for Transport. TfL is absolutely right to point out that this solution incorporates the full extent of what the DfT will allow it to do. And the Department for Transport seems very, very confused about cycling. A couple of months ago, the Minister (Mike Penning) responsible for road safety was asked about whether the UK would ever seen bicycle-only traffic lights, the sorts of things you see in every single other developed country. He'd keep an 'open mind' he said but he didn't want to see one set of rules for people on bikes and another for people driving cars. And then in the very same sentence he talked about people on bikes needing to be ahead of people driving motor vehicles at junctions 'because of the disparity of speed'. On the one hand, Penning believes there should be one set of rules for all people on the road, regardless of whether they are leg-powered or engine-powered, on the other he acknowledges people don't have the same acceleration on a bike as they do when they're driving a car. 

In other words, the UK will have to keep using traffic lights designed for motor cars to organise people on bicycles because the Minister can't make his mind up whether he wants one set of rules or two. And that means the Department of Transport will sit on its hands and do nothing. Unless, of course, organisations like Transport for London start saying that the rules need to evolve. I think, in a very subtle way, that's exactly what Transport for London is saying to The Times. The comment made by TfL seems to suggest that TfL wants to push the Department for Transport to set rules that more reliably match reality as far as cycling is concerned. At least I hope that's the case.

have to try and force your way across three lanes of

What's very encouraging is that Transport for London has also confirmed again that it is considering bike-only traffic lights at Blackfriars Bridge. I first wrote about this back in April when TfL hinted at a possible bicycle-only filter for people cycling over the Bridge and trying to turn north east into the City of London. According to The Times "cyclist-specific lights could be trialled elsewhere in London, with the northern side of Blackfriars Bridge likely to be one of the next sites."

This would be a great result and would significantly change the dynamic of this junction. Something like 10,000 people cycle through this junction every day and their existence was more or less ignored in the original plans for this new junction. After much protest, some small improvements have already been made: The bike lane pictured above, for example, was meant to be half the width it is now. A small improvement but worth fighting for, I think). Making it safer for people to turn right on their bikes would be a big improvement. All sorts of people head over this junction at the moment - folk on Boris bikes in suits, speedy road racers, you name it. There's no obvious or safe way for those heading into the City to turn right through the junction and so you end up with a sort of weaving of bikes in an out through the entire length of the junction. It's daft for cyclists and it's equally daft for drivers who have to watch out for the cyclists. I've watched lots of people just chicken out of turning right altogether, especially at night when there are fewer people about on bikes. They end up trying to turn right and then dashing for the pavement instead and crossing on the pedestrian crossing. 

My suspicion is that whatever ends up being built at Blackfriars will still look and feel relatively clunky compared to easy-to-use equivalents in the US or in Europe. And why's that? Well, a good part of it is down to intransigence on the part of Transport for London a couple of years ago. But now that TfL seems to be thinking about how to incorporate cycling as a genuine mode of transport, I think a real barrier to simple and safe cycling facilities here and elsewhere in London is the Department for Transport with its out-of-date thinking about cycling. I'm pleased that Transport for London is starting to make the right sorts of noises. I'll be even more pleased when I know my journey to work on a bike involves one less hold-your-breath-and-go-for-it junction. Then there are many, many more junctions to resolve. But at least it's a start. 


  1. Blackfriars is a total farce, having now driven through too (and walked and cycled), it is also shit for driving, there are too many lanes, too much confusion and too many traffic lights. One set go green only to be stopped by another red as soon as you're moving. And for cycling its at best been designed out and at worst deliberately lethal and as for walking with the desired crossings missing a hopeless failure. Whats more theres massive paved spaces in the middle of the road unused and a red light on the up hill section of the bridge.

    The so called planers who came up with this need to named and shamed and never allowed to tender for public works ever again, we need more protest rides, lets literally take a lane put out bollards and paint and make it, theres is more than enough room for a protected priority cycle lane, the width of a car lane, in both directions from elephant and castle to the junction with smithfield market.

  2. There is one thing that concerns me about the photo of the segregation at Bow - could it become effectively a barrier to cyclists progressing to the front at the lights? Clearly it will do a lot to prevent HGVs turning across cyclists' paths - surely even an HGV driver will notice he is mounting a kerb, even if he can't tell when he is mounting a bicycle and rider under his wheels - but cyclists will in effect be boxed in by the same kerb.

    Why does this concern me? Primarily because there are many cyclists who are unaware of, or unwilling to use, the ASL box ahead of them, who line up in the feeder lane. You can see this in your second pic, of the lights at the northern end of the northbound cariageway on Blackfriars Bridge. To be fair, it does rather appear that a white van has annexed the space in the ASL for itself so making it difficult if not impossible for cyclists to use, but as a daily commuter across this bridge I am all too aware that the lane clogs up while hardly anyone uses the full width of the ASL, as indeed is intended.

    Not being able to get to the front can place a cyclist in danger - being stuck some metres back alongside a HGV could mean being slap bang in its left-hook zone. The risk is probably less at Blackfriars, but is much worse at some other junctions, and it does make me cross when cyclists sit alongside HGVs in these feeder lanes, effectively acting as a barrier to others who are therefore either stuck in the same situation or need to hang back behind the HGV's rear end, when the cyslists could move forward and populate the ASL more fully.

    Of course, it is quite clear that ASLs are poorly understood, by motorists as well as cyclists. It should be clear enough that when the light is at red, motors are not permitted to move forward of the rear line, but it is a lot less clear what the rule is, for example, when traffic is moving still but very slowly, at a signal which is still green, or going amber. Does it function like a yellow-box junction, where the rule is don't enter until there is room to exit on the other side? I think not, although I would argue that it should.

    If advance phase greens are going to be introduced for cyclists, we are going to need clear advice and education, for drivers as well as cyclists, on how they are intended to work.

    I'm not entirely clear where the advance green phase is planned for Blackfriars - at the first set of lights as you reach the north end of the bridge? That seems to make sense as at this stage the traffic emerging off the embankment would be stopped at red, and cyclists would have clear space to proceed to the next set of lights, directly facing New Bridge St, where traffic either peels left to New Bridge Street or goes ahead to Queen Vic Street. I wouldn't think the advance green would be necessary for cyclists going up New Bridge Street as they can keep well left and use the cycle bypass outside the Unilever building.

    What we also need, however, is a significant widening of the cycle lanes from the approach to the first set of lights (Bridge North Bank), around the bend past the Unilever building, and into New Bridge Street. This stretch has lately become extremely congested at peak hours, with - in my estimation - considerably more cyclists than private cars or taxis/minicabs added together. The latest screenline traffic counts for this point were already showing slightly more cyclists than cars/taxis (around 26% of traffic cf around 32%) but a year or two later and in the summer weather, the balance has shifted even further.
