Lambeth Bridge shows us that TfL still needs a fundamental shift in design philosophy

Catching up with the latest TfL consultations, I was a combination of delighted and exasperated to see the proposals for Lambeth Bridge.

Delighted, because they reveal the political will to provide for cycling and walking, even if it means sacrificing a tiny bit of motoring capacity at these junctions.

Exasperated because even when the will is there, the technical capacity clearly isn’t. Just look at it.

Look at that splurge of tarmac.

TfL had a blank canvass here. They’re completely rebuilding the junction, which is currently a roundabout. The kerblines are going, the trees are moving, the drainage will have to be redone. It’s not like any compromise is being made to work within the constraints of what’s there now.

It reveals a lot about how TfL’s designers are approaching these problems. They had a blank canvass and they filled it with tarmac. Then they asked where they needed to fit some kerbs into it. Walking and cycling is still being designed to fit around the edges of motoring, which remains the natural rightful state of our streets.

And look at the absurd mess that has led to.

Look at the entry to Lambeth Bridge. They’ve painted an arrow on it to tell motorists to get out of the cycleway. How on earth did that happen? According to the diagram, there is only ever one lane of traffic able to head onto the bridge at any time. How did they get themselves into a situation where people might be driving in the cycle lane and need to be told to get out of it?

Look at the entry into Albert Embankment. What is that lane merge arrow painted on that grossly distended carriageway space for? Again, there is only one lane of traffic entering this street at a time.

These kinds of tarmac oceans, with arbitrary shifting kerblines and unclear routes through them, are why British junctions are confusing, stressful and dangerous — whatever mode of transport you’re using. There is a large area of tarmac here that in theory should never ever be used, even by the largest and longest vehicles, because there are no legal manoeuvres that would use the space, or at least, that wouldn’t normally and more safely and sensibly be performed using some other space. But what that tarmac does do is provide opportunities for people to make mistakes, to perform illegal manoeuvres, or to behave dangerously. The gaping wide entries into Lambeth Bridge and Albert Embankment do nothing for a law-abiding motorist except create confusion about where they’re supposed to be, but they do invite idiots to use the turn lanes and cycle spaces to jump queues or to make illegal turns.

What might this junction look like if designed with a less motor-centric philosophy?

Instead of washing an undercoat of carriageway all across the blank canvass, you’d start from the opposite default. The canvass is blank and the only carriageway you add to it is the carriageway that’s needed to accommodate the manoeuvres that are possible here. Who are the users who need to move through the junction, and where do they need to move from and to? Draw the paths that they will need to take through the junction.

Draw the paths that motorists would take through this space if following the turn restrictions and if following the most rational routes. Work out how you’d cycle around it, and how you’d walk around it. The result looks a lot like Dutch crossroads do.

Click to embiggen. (This is just a 5 minute scribble, exaggerated in places, to illustrate the concept. Please don’t tell me the turning circles are too tight for HGVs or the cycleways too narrow or there are white lines in the wrong place, I’m not trying to propose this as a working plan for the contractors.)

This kind of design enables all of the same turns that TfL’s design legally allows, and has exactly the same number of motor traffic lanes feeding into and out of each arm of the junction. Capacity for legal manoeuvres should be the same (but the illegal turns, lane misuse and simple mistakes encouraged by TfL’s original design become much more difficult). I’m not saying necessarily that this is what I’d want the junction to look like, because I wouldn’t necessarily accept the same demands of motor capacity as TfL, but if you do accept the demands TfL are working to, this is roughly how the junction would work if cycling were properly designed for.

The one impact I haven’t addressed with my crayons is that they would have to address turn conflicts across the cycleways — something that wouldn’t be an issue if we had normal priority rules. But there are multiple options available to solve that problem TfL could call upon — indeed, they already solve it in their own design, for traffic/cyclists exiting Albert Embankment, with a separate turn signal.

On his Quietways, the boroughs are taking Sadiq Khan for a ride

The Mayor is giving boroughs money to build Quietways for cycling and the boroughs are misappropriating it. Exactly as history told us they would.

My commute these days takes in a section of the Mayor’s new “Quietway 3” as I go an extra mile trying to avoid as much as possible riding on the roads of the City of Westminster, one of London’s 33 local government boroughs.

Although TfL has been advertising Quietway 3 as “complete” for some time, it’s only in the past few weeks that barriers have come down to reveal the first physical hints of its existence.

Filter bubble

At Boundary Road, on the Westminster/Camden border, the Quietway crosses the busy Finchley Road, the main arterial road to the M1. The Quietway here benefits from a mode filter which prevents through motor traffic on Boundary Road from crossing the Finchley Road.

A filter has existed here for many years already, built as part of a route in the failed London Cycle Network. But for the Quietway, it has been expensively rebuilt with a very slightly different alignment, and with a replacement set of traffic signals that include low-level cycle signals.* The only thing that is really new here, and which is highlighted as one of the big boons for cycling, is an additional banned turn to further filter motor traffic from Boundary Road.

Less prominently highlighted is the other big benefit of this banned turn, which reveals the real reason for the existence of this mode filter. The new banned left turn means that traffic on Finchley Road doesn’t need to be stopped for pedestrians to get a green man signal across Boundary Road. Like the LCN-era mode filter before it, this scheme has been designed to smooth and expedite traffic flow on a major arterial road by removing potential junction conflicts and minimising its red signal time. It is a motoring scheme dressed up as a cycling scheme in order to use up a cycling budget.

Signal failure

Elsewhere the evidence of Quietway 3 is even less forthcoming, but we can see from the consultations what is planned.

After Boundary Road, the Quietway heads into Westminster borough on Ordnance Hill. At times when the parallel Finchley and Avenue Roads are busy and congested, Ordnance Hill becomes the motorist’s ratrun of choice for racing to Swiss Cottage, and it’s crossed by a series of other popular ratruns. So what are Westminster proposing to do to transform this busy motoring racetrack into a Quietway that can deliver on the mayor’s vision for cycling?

They’re putting pedestrian crossing lights on signalised crossroads and replacing some footway paving with fancy stone. That will be the junction between Ordnance Hill and Acacia Road, two unclassified residential streets, both paralleled on each side by major through roads, but which have somehow become so busy with motorists cutting through that they need signals to manage the traffic and help people cross.

acacia

But it’s definitely a cycling scheme Westminster are spending the cycling money on, because alongside the expensive traffic signals and fancy stone paving, they’re going to paint advanced stop lines for cyclists.

Needless to say from schemes like these, Quietway 3 is going to be crap. Quietway 3 is not going to do the slightest to transform these streets into somewhere that, to quote the objectives of the scheme, people who are less confident in traffic will want to cycle. That these streets need signals and advanced stop lines to manage the traffic is shouting that they are a failure even before the letter ‘Q’ has been painted all over them. They are not, and will not be, the “quiet roads” that the mayor claims.

But that’s not what’s infuriating. Westminster misappropriating cycling funds is what Westminster does. It’s barely worth a sigh of resignation. What’s infuriating is that their behaviour could be seen a mile off, but the mayor has chosen to ignore every warning.

Reinventing the wheel

The rhetoric behind the Quietways is that this is some kind of innovation the likes of which we’ve never seen before, a radical programme that will deliver the transformation needed to make the mayor’s vision for cycling a reality. We’re told to wait and see how well it works rather than make premature judgements on twitter.

But we can see from Quietway 3 that there isn’t the slightest innovation between this and the the early 2000s London Cycling Network that failed before it — and which it largely follows. We know how well it will work because we have tried this countless times before. We know it doesn’t work, we know exactly why it doesn’t work, and we know what needs to be done differently to make it work.

The Quietways are failing for the same reason the London Cycling Network failed, and why the National Cycling Strategy before that failed, and why most of the Local Sustainable Transport Fund failed, and almost every one of the dozens of cycling policies since the 1970s that have proclaimed the same vision as this one have failed. They are being delivered piecemeal by nearly 3 dozen different local authorities and agencies few of which have the resources, expertise or adequate guidance to deliver it, few of which entirely share the mayor’s stated vision for them, and several of which are actively hostile to the objectives of the schemes they’ve been asked to deliver.

Boroughs and local authorities are well practised in redirecting ringfenced funds to their own priorities, as Paul M says of the LCN:

When we analysed how the City of London had spent its LCN grant money from TfL over the last few years, we found that typically the budget disappears down three roughly equal sized holes. One is the physical, tangible (for what it is worth) expenditure on paint and asphalt and — very occasionally –kerbstones. The second is spent on feasibility studies, impact assessments, traffic counts, yada yada yada, maybe even the occasional engineering design, carried out by consultants. The third, startlingly, is in effect a subsidy of the City’s own planing and highways departments’ salary bills.

This is the lesson that was learned from the 1996 National Cycling Strategy in an extensive report in 2005. It’s what led to the short-lived Cycling England, set up because the DfT discovered once again that trying to implement the National Cycling Strategy through grants to local authorities, who had their own agendas, didn’t work:

Weaknesses of the existing arrangements: Local authorities as delivery bodies
The first is how to work with local authorities, at present the main delivery agents, to deliver. Our main performance management system for local transport – the Local Transport Plan (LTP) system – identifies cycling as one of a large number of “products” that central government is purchasing from local government in return for the capital investment. But, in practice, our work with local authorities reveals that cycling, in most cases, is a significantly lower priority for transport investment than other outcomes, such as better public transport or small-scale highway improvements. Despite the transformation in the availability of local transport capital since 1997 and the increased investment in cycling under the LTP regime, levels of expenditure on cycling still lag well below those in successful cycling cities outside the UK. Central government cannot insist that local authorities adopt a particular cycling programme, nor would it want to, given that the direction of local government policy is to increase the autonomy of local government; however it can influence authorities through the LTP process.

This suggests that, if cycling is genuinely a national priority, more diverse delivery mechanisms need to be introduced, to complement and increase the impact of what local authorities are doing.

Cycling England was created to stop our wasting money on an inefficient and ineffective way of delivering cycling projects through grants to local authorities. (It was abolished to save money, by, er, going back to that inefficient and ineffective system.)

None of this is news. We know very well what doesn’t work in delivering mass cycling, and the mayor has been warned again and again. But Sadiq Khan seems thoroughly determined to learn this lesson the hard way.

*This section has actually been a TfL scheme, so one department of TfL is happy to rip another just as much as the boroughs are.

Tell TfL: reject GST NHS Trust’s bad ideas for Westminster Bridge

I started an only slightly facetious petition: Build safe bus stop bypasses on Westminster Bridge. Please do sign it and share it.

Facetious because it’s a tit-for-tat response to Guy’s and St Thomas’ NHS Trust’s* petition against bus stop bypasses on Westminster Bridge. I felt just slightly bad resorting to such childishness in a week when more than ever I felt the need for the world to sit down and resolve its differences through mature dialogue, compromise and understanding rather than mobs lashing out for all-or-nothing outcomes.

But only slightly facetious, because Guy’s and St Thomas’ NHS Trust set the terms for this game, shunning attempts at engagement and instead spreading misinformation to frighten people into opposing a scheme with little understanding of the proposal. If that’s how we’re playing this, bring it on.

What TfL have proposed

TfL want to continue their long-overdue modernisation of London’s roads, and next on their list is Westminster Bridge. Following established international best practice, the modernisation will provide clear space for cycling that is separate and protected from the carriageway and footway, making cycling a safe and attractive option while removing conflicts with motor traffic and pedestrians. Obviously these will also be separated from bus stops, with so-called “bus stop bypasses”:

WBS Visual 1 roundabout

Readers in London will be familiar with these tried-and-tested designs from the Cycle Superhighways. Readers in a number of European countries will be so familiar with them that they’ll wonder how they could possibly provoke a second thought, let alone how something that’s such an established part of the street furniture could lead to tit-for-tat petitions and blog posts.

What Guy’s and St Thomas’ NHS Trust propose

But in Britain we really are that far behind, and therefore bus stop bypasses are still alien enough to some people that Guy’s and St Thomas’ NHS Trust have been able to spread fear and misinformation about them — enough to gather 972 signatures for their petition, which calls on TfL to “consider the alternatives”.

GST don’t elaborate on the what the alternative is, and have declined to answer questions or engage on the subject, but we know what the alternative to separating modes is — it’s mixing them. GST have, at least, clarified that they are not opposed to cycle tracks, only to the bus stop bypasses. So the only possible conclusion is that rather than bypassing the bus stops on clear separate space, cyclists mix with bus passengers in the bus stops.

Obviously that’s an insane idea, and it’s difficult to find examples of such a thing being built. But this is Britain, home of the insanely badly designed cycle facility, so it’s difficult — but far from impossible. Here’s a bus stop on Royal College Street without a bypass**:

bottom-bus-stopped

(via CEoGB)

Guess how well that works?

This is on a relatively quiet street, with just one relatively lightly used bus route and a trickle of pedestrians and cyclists. On busy Westminster Bridge this would be carnage, and it’s utterly irresponsible of GST NHS Trust to advocate for such dangerous designs.

A serious point

Shared bus stop/cycle tracks are undeniably the logical conclusion of GST NHS Trust’s stated positions, but I’m not seriously suggesting that’s what they’re campaigning for. It’s clear they have no idea what they’re campaigning for, and not much better idea what they’re campaigning against. They are the latest in a line of organisations to make knee-jerk reactions to unfamiliar ideas — and threaten those ideas by spreading fear and misinformation about them.

So the serious point is that we need to actively stand up to the bikelash if we are to ensure that Go Dutch, Space For Cycling, and the progress that we have seen these past two years do not lose momentum.

We must engage with such organisations, when they are willing to engage, understand and address their fears when there are genuine fears, and keep plugging away at spreading understanding of best practice.

And we must laugh when such organisations become laughable, and mercilessly mock the likes of “Stop CS11” from the moment they lose all credibility.

And we must keep reminding TfL that we’re here — that the 10,000 who turned up in the rain to ask them to Go Dutch have not gone away. Which is why you should sign the stupid facetious petition.

* and for once on this occasion I’ll celebrate the NHS Trusts’ refusal to waste money on brand consultants who would advise them to name themselves something that means something and appeals to the public — say, “hospitals” — and instead always insist on being referred to as cold, faceless, bureaucratic, and eminently petition-against-able “NHS Trusts”.

** though for bonus weirdness, look carefully at the far left and you can see it does have a bus stop bypass — but for cars on a service road!

Use the bus in North London? The tube? Walk? Enjoy the park? This consultation needs your support.

TfL are consulting on “Cycle Superhighway 11”, from Portland Place to Swiss Cottage. Their proposals are to create an attractive and safe route around Regent’s Park Outer Circle and up Avenue Road, enabling people who would like to make their journeys by cycle, but are currently put off by fast and heavy motor traffic, to start riding.

But the proposals aren’t just great for cyclists and for people who would like to cycle if the conditions for it were right. They’re great for bus users, people enjoying the park, and anyone who walks in Swiss Cottage. Don’t ignore the consultation because you’re not a “cyclist”: these changes are for you too!

Bus users: get quicker journeys!

The proposals will see the Swiss Cottage gyratory removed, so that traffic goes straight down Finchley Road. Bus lanes along Finchley Road will be extended, and the Avenue Road section of the gyratory will become bus/cycle only, with dedicated facilities for buses turning at the end of their routes. So buses will no longer get caught up in the congestion of cars navigating the gyratory. Traffic modelling predicts significant journey time savings for the 113, 13 and 82.

The models are less favourable for some other routes, being neutral for most routes and suggesting increases for the C11 and 31. But traffic modelling consistently underestimates the positive effects that dedicated cycling infrastructure has on bus times. When cycle tracks were extended to Stratford for Cycle Superhighway 2, for example, traffic models predicted buses would be delayed by 1.5 minutes. In fact, no such delay occurred. Why?

First, TfL’s models don’t understand bike/bus dynamics. You know when the bus gets stuck behind a slow cyclist in the bus lane? When at every traffic light the bus has to wait for a sea of cyclists to clear out of the way before it can pull away from a green light? When the bus can’t pull out from a stop because cyclists have already started overtaking? TfL’s models understand none of that. The proposals for the Cycle Superhighway will see people switch from cycling on Finchley Road to cycling on Avenue Road, freeing up the bus lanes for buses.

Second, TfL’s models don’t understand how infrastructure changes lead to changes in our transport choices. The whole point of the Cycle Superhighway is to remove the barriers for people who would otherwise like to make their journeys by cycle. One of those barriers is the motor traffic using Avenue Road and Regent’s Park as a shortcut into town. Yet TfL’s models assume that after the changes are made, the same number of people will be driving, cycling, walking, and using the bus and tube as before — that nobody will change their mode of transport in response to the closure of a ratrun for cars, the removal of barriers to cycling, or the improvements to walking and public transport. But obviously people will change their behaviour, and there will be fewer cars around to get in the way of your bus than TfL assume.

And third, TfL’s models don’t look at the effects of crashes. Perhaps even more infuriating than long journeys are unreliable journeys. TfL’s plans provide a safe route for cycling, cutting the risk of nasty crashes on Finchley Road. Removing the gyratory will end the complex race track of ever changing lanes where motorists have to jostle to move into the correct position, meaning fewer prangs and smashes blocking the road. And the improved pedestrian crossings and spaces will substantially reduce the danger of pedestrians being hit by motorists flying around the bends of the gyratory. So fewer crashes, even leaving aside the obvious benefits of not killing and maiming people, means a more reliable road.

Finally, as if quicker journeys weren’t enough, note that some of the cycling journeys made possible by the Cycle Superhighway will be for people who currently use the bus. Many bus routes are now saturated to the point where increases to frequency or vehicle capacity are no longer feasible, and the only way to relieve overcrowding is to provide alternative means of making journeys. If you don’t want your buses to get any more crushed than they already are, Cycle Superhighways are what you need.

Walk in Swiss Cottage or use the tube? Get safer streets and better crossings!

With the proposals at Swiss Cottage, improvements for cycling are almost incidental to improvements that will be made for anybody who walks here — to the tube or bus stops, the shops, pubs, cinema, library or leisure centre.

The removal of the gyratory alone will make this a much more pleasant and much less dangerous place to walk. No more speeding traffic racing around the bends of the gyratory. No more trying to work out which of the many turn lanes and slip roads the motorists might erratically throw their vehicles at. And the removal of traffic from outside the tube station at the top of Avenue Road will make for a much better environment in which to walk and wait for buses.

There will also be some footway widening and continuous footways across driveways and side roads to emphasise pedestrian priority. There are also some excellent changes to the pedestrian crossings in the consultation which need your support: inconvenient “staggered crossings” (where you wait, cross to an island, then wait again for traffic coming the other way) are replaced with single stage crossings; and an extra wide crossing of Finchley Road is added outside the tube station. A small number of the changes might not be so perfect — so make sure you respond to the consultation supporting those that are good while suggesting where you would like to see further improvements to the crossings.

Enjoy Regent’s Park, but concerned by the speeding traffic? Get a safer, calmer park!

London is recognised internationally for the quality of its parks. But one thing currently mars Regent’s Park: the fast and heavy motor traffic that is allowed to drive right through the park on the Outer Circle. At rush hour the constant procession of traffic makes the park a noisy, polluted and unpleasant place to be; outside of the peaks, motorists speeding on this road make it an downright dangerous place for the recreational activities the park was designed for.

There is no need to be able to drive through the park: Outer Circle is paralleled on all sides by main roads that are properly designed and designated for through traffic. The reason motorists nip through the park is because, with fewer junctions and traffic lights, it’s easier to speed on the Outer Circle. As anyone who has used the park for even the smallest amount of time knows, law breaking by motorists is endemic in Regent’s Park, in close proximity to families trying to enjoy the park for its intended purpose. The 30 mph speed limit (already far too high for a park) is routinely flouted, and you don’t have to hang around long to witness motorway speeds.

That Regent’s Park can be used as a racetrack by motorists is an embarrassing anachronism that the proposals seek to resolve. Four of the eight gates to the park will be closed, except for a few off peak hours in the middle of the day. Motorists will still be able to access properties, visitor attractions and car parks. But for most through journeys the park will cease to offer an advantage over the surrounding main roads. I don’t think the proposals go nearly far enough, but the plans under consultation undoubtedly offer a massive improvement over the current unacceptable situation.

So if you use Regent’s Park — or would like to be able to enjoy it but are currently put off by the traffic barrier and the noise, pollution and danger it creates — make sure you respond to the consultation supporting the changes and suggesting improvements.

This needs your support: minority vested interests are fighting these improvements

If you want to see improved bus journeys in north London, or a better, more pedestrian friendly, less traffic dominated environment at Swiss Cottage, or a calmer, safer Regent’s Park, or if you want the option to make your journeys by bicycle where currently the roads are too dangerous or unpleasant, this needs your support.

Because to make these improvements for pedestrians, bus users, park users and bicycle users, the proposals must cut a favourite ratrun shortcut for wealthy Hampstead motorists who want to be able to drive a few miles into the West End. Instead of being able to nip down Avenue Road and race around Regent’s Park, if they want to continue driving private cars into the centre of our congested and polluted (but comprehensively public transport-served) city, they will have to contain themselves to main roads.

Though totally out of touch with the reality for normal people who rely on public transport, walking and, increasingly, cycling in the city, these motorists have loud mouths and the luxury of a lot of time on their hands. They are fighting hard to preserve their private shortcuts from Hampstead’s prosperous hillsides through Primrose Hill backstreets to their West End playgrounds, at the expense of the massive public improvements that are so desperately needed for the rest of us. They’re used to getting their way, and feeling that under threat they have mounted an increasingly desperate campaign of misinformation to frighten fellow motorists and NIMBY neighbours into joining their fight. Now they’ve made enough of a cacophony to start making politicians twitchy.

So make yourself heard

The minority vested interests are relying on the majority who stand to benefit from this scheme not noticing the consultation, or dismissing it as something that’s “just for cyclists” without spotting the broader benefits. So please make sure you respond to the consultation, supporting the scheme, highlighting the improvements that are most important to you, and making suggestions for how it could be made even better for you. It only needs 10 or 15 minutes, but the deadline is this Sunday.

A picture of a corpse

I saw a corpse on the street on the way to work this morning. Not for the first time, and, well, traffic violence is hardly worth commenting on these days. But a corpse is still enough to mark a day apart.

According to people on twitter, passers by were taking pictures of the corpse. People on twitter thought it distasteful, not right, undignified. Best move on, let the police and TfL clean up, nothing to see, nothing to share, nothing to comment on.

I didn’t get my camera out, but I took away a picture.

A line of cones and the blue folding “Police Road Closed” sign, gently swept traffic into a neat turn down a residential side-street towards the Clapham Road. The four lanes of the Brixton Road were incongruously empty. People walked in it and their comments and conversations could be heard. You don’t normally hear what anybody says on a London street.

Four red double-deck buses and one large tourist coach were all that was left of a queue that I guess must have been much longer. A TfL man must have worked his way down the queue, turning the buses back to send them around the diversion, and he was waving the coach through a three point turn. Beyond the police tape, empty and silent, the bus at the front of the queue sat at an angle, frozen in the middle of pulling out from the bus lane.

Beyond that, some way, a small pile lay in the middle of the northbound traffic lane. A jacket, leather I guess, and some other scraps of clothes. A few little pieces of rubbish left from where the paramedics and air ambulance trauma surgeons tried to resuscitate the corpse in the road. Perhaps they tried to replace lost blood. Perhaps they cut it open where it lay in a final attempt to get it started again. But they weren’t part of the picture, just a trace in the scene some time after their departure.

And then there was the corpse. Moved to the footway, just placed on the kerb, perfectly parallel to the northbound bus lane. Just lying there, out on its own in an empty stretch of street. They’d spread a crumpled greying-white sheet — too small — over it, and a bare, pale, very pale left arm and shoulder lay uncovered on the kerb, one of those old, broad, dirty stone south London kerbs. Not muscled, not skeletal, not obese, not hairy, a fairly typical arm for a fairly typical corpse.

And some way further on still, a motorbike stood on its stand where it had been wheeled onto the footway, out of the way. I don’t know motorbikes. Something dark, modern, clean and not obviously seriously damaged.

I only glanced over for a second, from behind the railings far away on the diversionary path, and I turned away and I kept walking but I took away a picture.

On the way home, the road was as it always is. Swept clear and back to the gushing open sewer of traffic it always is. Two kerb stones were perhaps a little cleaner. And flowers had sprouted beside where the corpse’s feet lay.

It’s not right to take pictures of corpses. It’s distasteful, undignified to share pictures of corpses. When people see pictures of corpses they’re liable to think there might be dead people behind the corpses, and they’re liable to become curious about who the people are and why they are dying. When people see pictures of corpses, looking human, looking humdrum, perhaps lying on boring kerbs, their own boring kerbs, in their own mundane streets in front of their own ubiquitous red buses, like they do every other day somewhere in this city, perhaps they might question why there are people dying on their morning commute, and why we keep just sweeping them away.

Show some respect, eh. No pictures. No front pages.

The quick, the cheap, and the inadequate

At the last Street Talks, a panel presented on the theme of “The quick, the cheap and the temporary: Speeding up the transformation of London’s streets and public spaces”. Hannah Padgett of Sustrans talked about projects that get communities to suggest and try out improvements to their streets and places; Brian Deegan talked about Royal College Street and the research that has gone into Transport for London’s new Cycle Design Standards; and Ben Kennedy from Hackney Council talked about their trial de-motorification of the Narroway.

It was all very encouraging to hear how transforming our streets to reduce the blight of traffic and enable walking and cycling doesn’t necessarily have to take decades and hundreds of millions of pounds, and so I look forward to Boris and the boroughs making some rapid progress rolling out this kind of flexible “segregation lite” around the city. It’s good to have it spelled out and spread far and wide: budget cuts are not an excuse.

Except I’m a little worried about the quick and the cheap. Sometimes I just can’t quite see how it can do the job. Take the proposals that TfL are currently consulting on for the A21 in Lewisham:

A21 Bromley Rd Canadian AvThere are two elements to this scheme: the long straight link, and the crossroads node. A mandatory cycle lane is proposed for the link — dedicated space found for cycling within the existing carriageway, but protected only by a stripe of white paint. This cycle lane looks like exactly the sort of place that Royal College Street-style segregation could be quickly and cheaply implemented. It would be far from perfect — minimal separation from passing trucks, and only on one side of the road — but it would at least be a quick and cheap interim solution that could be in place on the street within days of a consultation ending.

The junction is the problem. Perhaps I just lack the imagination but I can’t picture any amount of the quick and the cheap segregation-lite making a safe, inviting and effective crossroads — especially one in which cyclists have to get past a long dedicated left-turn lane. And fixing the junction is the main issue, since it is junctions that are the least safe and least inviting part of our streets.

The best way to solve crossroads — and perhaps the only proven way, since Danish and German junctions don’t have such a great record for cycling safety and convenience — is the Dutch way: providing good, direct, high-capacity dedicated space with plenty of separation — in space and, where there are signals, in time — from the jostling and turning motor traffic. And that can not be done with a wheelbarrow load of armadillos.

@AnoopShah4 has already reached for the crayons box and sketched out a basic idea for the sort of things a junction like this needs. Carriageway narrowing, removing the left-hook lane, and putting in dedicated tracks set back from the carriageway:

Suggestion_A21_Bromley_Rd_Canadian_AvThe fact is, the carriageway on the A21 is in the wrong place. It’s the wrong shape and size. Fixing it, to make it the right shape and size, will require at least digging up the road to move the kerbs, but probably also moving some of the things on the street (like lamp posts) and under it (like rainwater drains). That’s not cheap and easy (well, not compared to Royal College Street; it’s still a bargain beside the M74), which is why in TfL’s plans, there is only some minor tinkering with the kerbs to tighten up the turnings in a couple of places, while absurd abominations like that left-turn lane are untouched.

It’s not cheap and easy, but without digging up the road, I just can’t picture how this junction could ever match the Mayor’s promise for TfL schemes:

Timid, half-hearted improvements are out – we will do things at least adequately, or not at all.

The current plan out for consultation is inadequate; to do things at least adequately here would require the mayor to spend some money correcting the carriageway.

DSC_3289

The Dutch had carriageways that were the wrong shape and size too, but they’ve slowly worked their way through them correcting that, adding their cycle tracks as they go.

This junction is far from alone amongst London’s main roads — the ones which require dedicated space for cycling — in being a place where I can’t see how the quick and easy could work, and it’s not just junctions where this is a problem. A great many of our streets seem to have been assembled quite clumsily, with carriageway and lane widths bouncing around erratically according to the space available between buildings, obstructions strewn across footways without thought, and decades of added and moved and sometimes removed buildouts and islands, stacking lanes, bus stops and loading bays. They’re a mess, and trying to retrofit them for cycling could only make them an even bigger mess. To do things adequately, you’re often going to have to sweep away the accumulated mess, cast off the constraints of the motor-centric streets we’ve inherited, and do things properly. But we managed to put the money and effort in to install all of those ill-conceived left-hook lanes and junction stacks in the past. We should be able to find the same to now fix those mistakes.

The tragedy around The Commons

I did a video, because I was too lazy to think about and research and write up a topic properly, and because I needed something for testing editing software. It’s about shared use foot/cycle paths in parks. I know! Super exciting, right?

This means that I now not only hate the sound of my voice, I hate my mannerisms generally. I was not entirely unaware that smiling/grinning/laughing doesn’t look good on me, but, damn, I do all those other things as well?

But in a fit of reckless impulsiveness I thought I’d go ahead and publish it anyway.

It starts with an apology, but I’m really not sure that one is ever enough.
