De Wereldgezondheidsorganisatie WHO heeft een nieuwe versie uitgebracht van HEAT, een model waarmee de gezondheidseffecten van maatregelen ten aanzien van fietsen en lopen zijn door te rekenen.
By way of a follow-up to last week’s post about reducing the need to stop at traffic lights while cycling, I thought I’d take a look at exemptions to signals – how they work in the Netherlands, and how they could be transferred to the UK.
This is a bit of a hot topic (as far as hot topics go) in cycle infrastructure design, and also something that could offer benefits for pedestrians – pertinent, as we’ll see, to aspects of the Superhighway plans. just announced by Transport for London.
The basic Dutch principle is that if someone is making a right turn by bike (our left turn, obviously) at a signalised junction, they shouldn’t have to stop. Not only is this convenient, it’s also safer – people cycling, turning right, don’t need to go anywhere near the junction itself.
Amazingly the Dutch have been doing this for a very long time. Mark Wagenbuur (BicycleDutch) showed me this example dating from the 1960s, in the Overvecht area of Utrecht -
This signalised junction is completely bypassed if you wish to turn right by bike (much as it is if you were walking). Good design, even if it is clearly in need of renovation, being about fifty years old!
Here’s a more modern example of the same design, in Amsterdam -
In fact, we actually do this already in Britain – but badly. We simply allow cycling on the footway. Either this is a simple footway conversion – ‘you can now cycle here, off you go’ – or it’s deliberate design, like (for instance) on Old Shoreham Road in Brighton, where you are allowed to cycle onto the pavement to make left turns.
It’s a nice idea, but it’s far from ideal, not just because it creates conflict and uncertainly between people walking and cycling, but also because there’s no continuity through the junction.
Happily it seems that moves are afoot to try and bring Dutch-style design to the UK, with cycle tracks, clearly separated from both footways and the carriageway, extending around the corners of signalised junctions, and remaining outside of signal control.
Here’s a detail from a presentation made at the latest LCC policy forum, by Transport for London’s Brian Deegan -
It’s not quite perfect, but the principle are exactly right. Turning left is possible at any time, regardless of what the signals are doing. Likewise, the interactions with pedestrians are managed correctly, with pedestrians having priority across the track on zebras, on both arms of the junction – reaching a waiting island, and then crossing the carriageway with signals.
So this is how someone walking might move across this junction -
They can, of course, cross the ‘signalised’ bit whenever they want to, if the road is clear, because UK pedestrians don’t have to obey the red man.
Flipping a picture of a junction in Amsterdam, we can see how this might look in Britain.
The woman with the dog has crossed the ‘zebra’ bit over the cycle track, and is waiting for a green signal at the carriageway. Slightly confusingly, the Dutch use zebra markings across signalised pedestrian crossings too. (This is so that they can function with pedestrian priority at night, when traffic signals are turned off). But Brian’s example is how it might look in the UK.
Brian himself is pushing hard for an implementation of this kind of junction somewhere in London. His actual intention is for it to operate as a form of ‘simultaneous green’, with people able to cycle across the junction in any direction, at the same time, while all motor traffic is held – and pedestrians also able to cross at the same time, because the ‘signalled’ bit of the crossing doesn’t involve anyone cycling.
But it seems that some people in TfL are quite sniffy and sceptical about how this would actually work – Brian related how he had been told that the ‘zebra’ and the ‘signalised’ parts of the pedestrian crossing should be staggered, or offset, so that pedestrians don’t get confused into thinking that the whole crossing is a zebra. (Yes, seriously).
Funnily enough, I was in Bristol the other weekend, and, well, they are actually building something like this already.
This is the new cycle track along Baldwin Street, still under construction -
It will be bi-directional, which is less than ideal, but I think Bristol have actually pretty much nailed how this design approach should work. The cycle track passes behind the traffic signals, meaning there’s no need to stop. There’s even a hint at a Dutch protecting island on the corner, and the pedestrian and cyclist parts of the crossing (heading to the left) are clearly separated. Pedestrians cross the track on a hinted ‘zebra’, and then wait on an island, if they have to, for the signalled part of the crossing.
The ‘zebra’ has to be unofficial like this, because doing it officially would currently require Belisha beacons, and zig-zag markings – rendering something that should be quite simple very messy. So I think Bristol have taken the right approach – it’s quite obvious that it’s a crossing, even if it isn’t done by the letter.
Are people confused by this design? It would seem not.
I stood here for a while, and nobody appeared to feel the urge to march across the road, convinced that they had priority on a zebra, all the way across it. It’s really quite obvious what’s going on.
The rest of the track will, it seems, have this same kind of treatment at straightforward signalised pedestrian crossings.
A little hard to see, because it’s obviously still under construction, but pedestrians can cross the cycle track on this ‘zebra’, before waiting on an island at a signalised pedestrian crossing. Simple, and it means that people cycling along the road don’t have to worry about stopping for the signals; they just have to yield to pedestrians at the ‘zebra’.
The original plans marked this arrangement much like a ‘give way a footway’ -
This would not have been a bit messy, I think, and I’m pleased to see Bristol using the best approximation of a Dutch approach that they can manage.
So, can this be copied in London, and elsewhere in the UK? Definitely. Here’s a pedestrian crossing, from the new Superhighway proposals on Lower Thames Street.
The whole crossing is signalised. But why not do what Bristol are doing, and only signalise the bit across the road, with a zebra (or ‘zebra’) across the cycle track, at the top? (Note – this would have the added benefit of shorter pedestrian stages).
Likewise, just to the west of Blackfriars Bridge -
Do we really need to make people walking go out of their way, on a two-stage staggered crossing, just to get across a cycle track? Surely a simple ‘zebra’ marking would suffice. Why make our lives more difficult with all this staggering, when the cycle track could be crossed directly on zebras?
So I’d love to see all this unnecessary signalisation removed from these (very promising) plans, and replaced with zebra markings. It would make everyone’s lives much better. These plans would make a substantial improvement to the pedestrian environment as they stand, but i think they be even better.
It would also provide firm support for Brian Deegan’s attempts to implement his simultaneous green junction plans elsewhere in London, – as well as support for the sound principle of exempting people cycling left at junctions from signalisation.
Bristol are showing us how it can be done. Why over-complicate things?

I wouldn’t mind so much if the arguments being presented against the new Superhighway proposals in London were actually considered, and credible. But they’re not. In many cases, they’re ridiculous. Let’s examine the recent City of London response, which sadly is pretty much nonsense, from start to finish.
Michael Welbank, the City of London’s Planning Chairman, states that the City
support[s] the two routes in principle
Which sounds promising, until you consider that – from bitter UK experience – a ‘cycle route’ can mean absolutely anything. A bit of shared pavement, a useless stripe on the road – take your pick.
Simply supporting the principle of a ‘route’, therefore, is meaningless, without any detail on the quality and nature of that route. And it is the nature of these Superhighways that the City of London are specifically objecting to. As Mark Boleas, City Policy Chairman, states in the same press release -
We support the concept of cycling superhighways but have considerable reservations about the current proposals
So not really ‘support’, at all – ‘considerable reservations’. Indeed, what ‘support’ the City are offering is merely for a ‘route’ of some description – the vague, undefined ‘concept of cycling superhighways’.
What form of ‘Superhighway’ do the City think TfL should be employing, instead of the current proposals? They don’t go into detail, but a clue is here -
Mr Welbank said the Square Mile’s dense street pattern meant pedestrians, cyclists and drivers all needed to share the space.
‘We’re trying to get all street-users to adapt constantly to each other and avoid a ‘It’s-my-space!’ mentality.’
Let’s pick this apart. The City of London – as far as I am aware – isn’t proposing to remove footways, and make pedestrians ‘share space’ with drivers. Indeed, pavements have been widened in many places in the City of London. More pedestrian-specific space has been created. How do the City’s public realm schemes fit with their own arguments about pedestrians and drivers ‘all needing to share space’? Are the City actually worried about pedestrians (and drivers travelling alongside the footways they are on) having an ‘it’s-my-space!’ mentality? I doubt it.
So the impression created by these comments from Welbank is that what the City of London is really objecting to is, specifically, the principle of protected space for cycling on the roads in question. Pedestrians and drivers are not ‘sharing’ anywhere in the city of London, nor will they be any time soon. The only ‘sharing’ the City is talking about is of a particular kind – mixing people cycling, with motor traffic. These two modes ‘adapting constantly to each other’.
Now, the charitable interpretation of these comments is that Welbank and the City of London haven’t actually worked out which roads are involved in this Superhighway scheme. That is – they’ve responded without examining where the Superhighway will run.
That sounds unbelievable, but note that Welbank is talking about a ‘dense street pattern’, which bears absolutely no relation to the roads on which the Superhighway will actually be built. Namely – very, very wide roads, carrying tens of thousands of motor vehicles a day.
The less charitable interpretation is that they do know which roads are involved, but haven’t got the first clue about how attractive this ‘sharing’ approach might be on them, or are simply advocating ‘sharing’ because they want to maintain the status quo.
Let’s take a look at the amount of motor traffic on the roads involved – the route in the pictures above. Lower Thames Street, which will form a large part of the East-West Superhighway through the City of London, carries 49,000 motor vehicles a day, including over 4000 HGVs, 8000 LGVs, and nearly 2000 buses and coaches.
The Embankment is scarcely any better, with 61,000 motor vehicles a day, including around 3000 HGVs, and 9000 LGVs. Upper Thames Street by Blackfriars station carries 40,000 motor vehicles a day, with around 10,000 HGVs and LGVs, in total. You can see these figures for yourself on the Department for Transport site.
So these are plainly very busy roads, that are wide, and fast. There might be some people cycling here already, ‘sharing’ and ‘constantly adapting’ to the motor traffic flowing around them, but to present ‘sharing’ as a realistic design approach for cycling on these roads is extremely fanciful.
These roads are dangerous and hostile to the few people fit and brave enough to cycle on them. They include some of the most deadliest junctions in London, places where experienced cyclists are killed or seriously injured with horrible regularity, one of the most recent being Bart Chan, hit by an HGV on Upper Thames Street in May this year. These awful collisions will continue to happen if, instead of well-designed Superhighways that separate people cycling from HGVs, buses and motor traffic, we get the City’s apparently desired approach of ‘sharing’ and ‘constantly adapting’.
In addition, we have a vivid annual demonstration of how actual demand for cycling along the Thames is massively suppressed.
For just one day of the year, thousands of people fight their way into central London – carrying bikes on cars, or walking or cycling on footways – to experience the joy of cycling on these roads.
Is ‘sharing’ with the tens of thousands of vehicles using these roads, per, day a realistic prospect for these kinds of people? And if it is, where are they for the rest of the year, when the roads in the last two pictures look like this?
I don’t think the City of London are really thinking about these kinds of people, to be honest. They cannot seriously be advocating those young children ‘sharing’ with the HGVs you can see here.
So my impression is that they simply don’t like the idea of space being taken away, because they are worried about delays to motor traffic, and are proposing ‘sharing’ the City’s road network, not because they think it’s realistic or attractive for ordinary people, but because they want to maintain the status quo.
They can’t come out and say that, of course, so they instead have to employ these arguments that don’t stand up to scrutiny. And there are other poor, weak or self-defeating arguments in that City of London press release. For instance -
more thought needs to be given to the knock-on effects on noise and air-pollution.
Really? We can’t make cycling – a mode of transport that doesn’t pollute, and is (virtually) silent – more attractive, because that might affect noise and air-pollution? Are the City of London seriously making this argument?
Likewise, the City have taken the deeply unhelpful approach of spinning these proposals as being hostile to pedestrians. The release starts -
Square Mile planners are urging pedestrians to have their say on plans for new east-west and north-south cycle ‘superhighways’
Pedestrians tend not to lobby for their interests but this is a chance and I would encourage them to have their say before central section consultation closes on 19 Oct. Crossing times might a lot longer in places.
Is this true? Where has the City got this impression from?
The TfL summary of the proposals states that there would be
longer waits for pedestrians at some signalised crossings.
Which the City has presented as ‘a lot longer’ (I’m not sure how they’ve established this).
But it’s quite clear that, overall, these Superhighways would be hugely beneficial to pedestrians. Why?
For a start, as TfL state, they will involve
Increased distance between the footway and the road, creating a more pleasant pedestrian environment
Instead of walking a few feet from HGVs and buses travelling at 30mph, people will instead be walking a few feet from people cycling, at much lower speeds. Far more pleasant, as TfL argue (and, indeed, much safer).
Not just that. Because the vast majority of the space for these Superhighways is coming from what is currently motor traffic space, the distance across the road itself will be much shorter. That means shorter crossing times, not longer ones.
All the elements in these Superhighway proposals that will make life better for pedestrians probably merit a post in their own right, but here are just some examples.
Because Blackfriars Road is being narrowed by the cycle tracks – guess what, TfL can put in a ‘straight across’ pedestrian crossing, rather than a staggered one.
Better for pedestrians.
Pedestrians coming across Blackfriars Bridge currently have to negotiate two signalled crossings across two slip roads. Well, one of those crossings will now be bikes-only. Much easier to cross.
Many other streets and roads involved in this scheme are being closed to motor traffic, or involve banned turns. Constitution Hill is being upgraded, separating people walking from people cycling. Parts of the Tower Hill gyratory are having private motor traffic completely removed. Horse Guards Road is being closed to all motor traffic, except official vehicles. I could go on (and will, in another post!).
Of course, there are some problems with these routes that I think could be ironed out, from a cycling and walking perspective. But the essential truth about these routes is that they will have a positive impact on the quality of the walking experience.
So, yes, like the City of London, I would urge pedestrians to ‘have their say’. But, unlike the City of London, who don’t seem to have looked at these plans in detail, and appear to have assumed them to be hostile to walking, I do so because they will make life for anyone walking in the centre of London much better, not worse.
Finally, let’s briefly return to those DfT figures for motor traffic levels on these roads. They’re quite interesting, if looked at over the last decade. Here’s the pattern on Upper Thames Street.
There’s a bit of noise here, because the counts are only carried out on one day. But clearly, motor traffic here has fallen, quite substantially. Over the last 3-4 years, its about two-thirds of the level it was in the early part of the 21st century.
Or, to look at this another way, motor traffic on Upper Thames Street – on the same road layout – was about fifty percent greater a decade ago. That same road layout could cope with those higher motor traffic levels, so why on earth will it not be able to cope, today, with the proposed reduction in capacity for these Superhighways, when the motor traffic flowing on it is much lower?
And it’s even simpler than that. In broader terms, these Superhighways are really about making the most efficient use of the available space on London’s roads. Cycling, as a mode of transport, is extremely efficient, compared to motor traffic, so that means we should be making it as easy, safe and attractive as we can, for ordinary people, to free up space on the road network. More people cycling means that those essential uses of the road network – deliveries and so on – will be made easier. And – heaven forbid – in a modern, 21st century city, we really should be prioritising a mode of transport that will make a difference, in so many ways. Even if that does mean taking a lane away from four- or five-lane roads.
For all these reasons, the City of London need to reflect on what the Superhighways will offer London, get to grips with these proposals, and change their position.
A new bridge over the Thames in East London would only benefit ‘former Tory MPs’, a Newham councillor has claimed.
Councillor Airdrie Dalden is objecting to plans from Transport for London which include a bridge between the borough and the Royal Borough of Greenwich on the south of the river.
Quoting the example of journalist Matthew Parris, councillor Dalden said: “The vast majority of people currently crossing the Thames here are former Tory MPs in swimming trunks. Women of any ethnic group who wish to wear modest clothing, and I count myself in that category, are not going to put on a swimming costume and cross the Thames. Swimming is a discriminatory form of transport.”
Parris was criticised by the Port of London Authority in 2010 after writing about his experience of being swept a mile upriver when swimming across the busy commercial waterway at night.
Mayor Boris Johnson claims that the new Thames Gateway Bridge across the river would link the transport poor Thamesmead estate and Woolwich development area in Greenwich with residential and redevelopment areas around Beckton and the Royal Docks in Newham, creating opportunities for one of Britain’s most deprived boroughs.
But Councillor Dalden told AWWTM that the money Johnson proposes spending on the bridge would not “benefit every aspect of Newham, which is an ethnically diverse borough.”
“You look around and of the people who are crossing the Thames here, they do not belong to wider ethnic groups. The majority of swimmers are former Tory MPs like Matthew Parris and Boris Johnson. Fact.”
Transport for London are now considering a compromise solution which will involve building half a bridge.

I wrote a piece last month about the appropriate long-term response to people breaking the law while cycling – in short, it’s to fix the street they’re cycling on, so they’re not breaking the law anymore.
For instance – if people are cycling ‘the wrong way’ on a one-way street, well, the correct response is to make sure that two-way cycling is appropriately designed for on that street. If traffic is low enough, then that might amount to nothing more than just allowing it with a simple exemption. If there’s more traffic, then the solution will probably involve some engineering – or removal, or displacement, of that traffic – to make two-way cycling safe.
I also mentioned that – if there’s a problem with red light jumping – a proper long-term response is to look at how these signals are designed, and to assess whether they are even necessary.
Let me give a concrete example. In April this year, I made a short trip in the city of Utrecht.
This was a distance of just over a mile, right through the centre of the city. On a heavy Dutch bike, it took me about five and a half minutes, in total – including any stops. That’s a very respectable overall average speed of 11 mph, given that I was stationary for 40 seconds at one signal.
The reason I was able to make such good progress is because, as we’ll see in the video, I only had to make that one stop. There was just one traffic light I had to deal with on this journey. The rest of it didn’t involve any stopping or waiting at all, mainly because there aren’t any other traffic signals on this trip.
With so few traffic lights – guess what! – there isn’t very much red light jumping by people cycling. Misbehaviour just evaporates when the street conditions are adapted to favour walking and cycling.
By complete contrast, the very next day, I arrived back in London, getting a train into Liverpool Street from the ferry terminal. Here’s the journey I made by bike, to Victoria -
This trip was just three and a half miles – only about three times as long as my Utrecht trip – but it included 32 traffic signals. That’s a signal roughly every 175 metres, and I estimate that I had to stop at roughly half of them.
It was hugely frustrating, coming, as I did, straight off the ferry from a country where traffic signals are much, much rarer in urban areas. Even where they do exist in the Netherlands, they will almost always exempt cycling from right turns (the equivalent of our left turn).
So it is possible to deal with red light jumping, not by clamping down on it, but by creating conditions where people cycling simply don’t have to deal with lights at all.
Het gaat de goede kant op met de registratie van verkeersongevallen. Dit blijkt volgens de SWOV uit de jongste cijfers over de verkeersongevallenregistratie.
