A zebra can't change its stripes

Zebra crossings are in my opinion, the best type of crossing for pedestrians. They provide priority for pedestrians crossing, all of the time, and so cause the least delay for pedestrians. Obviously they are not appropriate all of the time, but in most urban settings, they are.

UK Zebra crossing. Also this one is a bit famous
I also believe that the UK has a much better design when it comes to zebra crossings compared to other countries. The flashing yellow beacons make it very clear as a driver where zebra crossings are. When I'm driving, the yellow beacons are a message to me to drop my speed and to expect pedestrians may want to cross.

A zebra in the Netherlands. To British eyes, the crossing is much less visible
However, the zebra crossing regulations are potentially in the way when it comes to cycle provision. Zebra crossings over cycle tracks are common in the Netherlands. However when it comes to attempting to implement them in the UK, they have to be horribly over engineered because the regulations are designed for motor traffic.
I visited Bristol on Saturday (guided by Wheels On The Bike) and had a look at Baldwin Street. In my opinion it is one of the best designed pieces of cycling infrastructure in the UK to date. Bristol has used a bit of a work around to get zebra crossings on the cycle track

Is it an actual zebra? It certainly has the stripes
It is clear when cycling that this is a zebra crossing. Because cycling speeds are lower, flashing beacons are not needed, nor markings to say not to stop near the crossing.

If you want evidence that this design works at slow speeds, visit a private car park. The majority of car parks in the UK have zebra crossings consisting only of zebra stripes, yet I hardly ever have problems with motorists ignoring priority

From my University campus. Not regulation, but everyone knows what this means.

That's why regulations for zebra crossings on cycle tracks should be relaxed. Belisha beacons are great when it comes to zebra crossings for motor vehicles, but are completely unnecessary when it come to cycling provision.

TFL want zebra crossings for a cycle track as part of CS5

It will be interesting to see if they have to stick to the letter of the regulations, or whether some elements will be relaxed by the Department for Transport.

Old Street redesigned

TFL are currently releasing lots of consultations at the moment. This part of the better junctions scheme, which is planned to improve 33 junctions for cycling. Some of these have already been released, ranging from disappointing (such as Elephant and Castle) to needing very few changes to be very good (such as Blackfriars)

From the consultations so far, I think I can raise the following two points:
  • TFL have realised that good cycling infrastructure should be designed to the same standards as roads are
  • However, TFL have not realised that cycles need to be treated differently to cars
I think these are made most apparent in the consultation for Old Street Roundabout. This includes some very promising cycle tracks through the junction, and most importantly, all left hook conflicts have been removed. Also, not a single ASL in sight, which is also another huge step forward.
Promising, but the cycle facilities still need improvement
However, most of the problems in this design stem from the fact that TFL are still treating cycles the same way they would treat cars. This is apparent by the excessive signalisation of cycle only conflicts, and of pedestrian and cycle interactions.

Yes, there are conflicts, but cycles don't need signals to deal with them.
That's why I've done a redesign of TFLs consultation plan. This isn't because you should oppose TFLs plans, far from it. However, it needs to be shown to TFL how cycle tracks need to be designed, because bikes are not cars, and so interactions aren't the same.

Much safer for cycling, and much quicker to cycle through
The T-junctions now have cycle track crossings on all arms, and allow cycles to make a left turn or go straight ahead at all times without signals. Cycles also don't have to wait for pedestrian crossings. Pedestrians cross the crossings either on an informal crossing, or though a zebra crossing, however my diagram has these missing.
Closer to a standard Dutch junction

All the changes can be seen in the PDF of my amendments

Overall, I think people need to partially support the TFL proposals. They are among some of the most promising UK cycling infrastructure plans to date. But there are problems, and to fully support the proposals purely because they are better will, in my opinion, mean we will never progress to anything better. I know TFL look at my plans, for Kings Cross my designs made it into the appendix. Therefore when responding to the consultation, link to this blog post, and show TFL how to improve their designs even further.

Too much praise leaves you where you are, but well put criticism will lead to progress.

Heavy Duty NL

I've moved! I'm no longer living in Maidstone, and am now studying at the University of South Wales, near Pontypridd. However, I am still going to keep the name that everyone knows me by.

It's been almost a week now since I picked up my Heavy Duty NL. It's a Dutch import from Royal Dutch Gazelle, and frankly, I think it looks stunning.

My bike outside my student halls

Since it is a Dutch import, there are features on it that are very uncommon in the UK. Firstly, the back wheel has a lock built in. Without the key, a metal bar goes between the spokes in the back wheel. This means no key, no movement.

I wouldn't leave it for long on the wheel lock, but it's great for going into a shop for a few minutes

The bike has front and rear racks. I'm yet to properly utilise the front rack, although I have used it to carry my jumper when I've gotten to hot riding (it's possible to multi-task, eating, taking off clothing ect!). I'm planning on getting a crate so that I can carry shopping or any other items. As a student, the front rack is also the perfect size for carrying a crate of beer!

Although today I used it to carry potatoes.

The back wheel has a seven speed hub. I'm probably going to do some modification to the gearing, as my student accommodation is on a very steep hill (welcome to the Welsh Valleys!) so it's a bit of a struggle getting up some of the hills at the moment. The chain is also fully enclosed by a chain guard, so no more oil or grease on my trouser legs.

Low maintenance, important for a bike designed for transport

So would I recommend a Dutch bike? Certainly. Although you can feel a little bit more vulnerable in UK traffic because it won't go quite as fast, riding one of these is by far more enjoyable than trying to ride a sports bike to the shops. I love my sports cycling and racing around in lycra, but that is a completely different activity to travelling to lectures carrying textbooks.
And yes, it just about gets on the train!
I bought my bike from Rob at Really Useful Bikes in Bristol. And the Royal Dutch Gazelle website is here.

The negatives of positivity

Earlier this week I wrote a blog post about the East-West Superhighway, entitled 'Get off the hype train'. I suggested that you only partially support, rather than fully support. This is despite it being probably the best cycling scheme to be proposed in London, and well, probably the rest of the UK.

Now I would like to explain my reasoning, with a little bit of help from Royal College Street.

Hooray for pointless conflict!
I'm sure most people know about the Royal College Street scheme. It consists of plastic armadillos and planters, which are are constantly breaking. There have been plenty of blog posts about the failings of the scheme, so I won't go into detail.

An Armadillo, working exactly as planned.

Last night, Camden Cyclists tweeted this:
Just like the original Royal College Street, there are things to be praised. Space is being given to cyclists, and often conflicts with parking have been removed.
Why the loading bay conflict?

But there is terrible stuff here. There are loading bays with door zone problems, the fact armadillos don't really work, and also an appalling bit where cycles and cars are expected to just merge together through a pinch point

This is incredibly dangerous. Why are Camden Cyclists supporting this?

The big problem here is the amount of praise and awards. Here is a tweet from a Camden councillor:
Why does Camden need to improve on the Royal College Street scheme. They know they got loads of awards and praise the last time, so why bother? There is no point working any harder if the results are the same. The level of effort required for praise has been set so low, the designers needn't consider proper cycling infrastructure. Just place out a load of armadillos, and the cyclists will be happy.

This is why I have my reservations about praising the East-West superhighway too much. Yes, it deserves praise. But too much praise, and it sets the benchmark too low.

London and the rest of the UK will never progress while praise is just given out on a whim.

Get off the hype train

Last week I went to the Netherlands, on one of David Hembrow's study tours. You can look at photos as long as you like, but to fully understand Dutch infrastructure I believe that you have to see it first hand.

Standard cycle path, with separate space for pedestrians.
I will do a proper blog post on the brilliant infrastructure I saw, however this post is more focused on the not so great infrastructure that came from London while I was away.

Feel the space, ignore the design

Don't get me wrong, the two new superhighway routes are a huge step forward. The amount of space being allocated to cycling is great and the chance to have safe cycling routes along Embankment and Blackfriars junction is a great proposition.

However, they don't deserve the hype that they have been given. The design of these routes is clearly lacking, and in many places, it's appalling. I fear with the amount of hype these routes are being given, we cannot progress. If TfL get the message that these are good enough, this is all we will ever get.

I think TfL has a surplus of traffic lights. Why innovate when there are solutions that work in other countries?

Take "early start" as an example. For years, cycle campaigners have been telling TfL that the addition of these to Bow Roundabout is not enough. With 60% of cyclists refusing to use the roundabout and continuing to use the flyover, it is pretty clear that it is an awful design. Yet I am still told that I have to wholeheartedly support the new superhighway, despite Early Start being used 3 times just on Parliament Square

Staying on the superhighway? Wonderful.  But it's a pile of crap if you are going anywhere else. This is one of the sections I recommend you say "no" when asked to support this in the consultation.

Tegelijk groen

I have actually already done plans for two parts of the superhighway, at Parliament Square and the end of CS7 at Upper Thames Street. However, these were made before I knew about the wonderful Simultaneous Green Junctions that exist in the Netherlands.

Simultaneous Green would solve many of the problems with the new superhighways, namely that the junctions are crap. The fact that TfL have gone with two way tracks leads to problems with connectivity. Simultaneous Green solves this without a dangerous two stage turn which kills in Denmark.

No problems with this two way track connecting to the other roads on this crossroads in Assen. Location here.
Below is a video of Simultaneous Green working at a 10 lane junction:

The first design I have done is on the East-West Superhighway, at Blackfriars. This junction has excessive traffic lights, with all movements through the junction but one, require cyclists to use two sets of traffic lights. By replacing these with a simultaneous green junction, at worst cyclists will only get one set of traffic lights here, and at best, zero.

Sea of traffic lights replaced by one junction., allowing cyclists to take the most direct route.

The second design is the junction of Embankment with Savoy Place and Savoy Street. I've replaced the two stage ASL with a simultaneous green junction, which is quicker for cycles. I've also made Savoy Place two way for cycles.

A new type of roundabout has to be test for months. A new type of ASL doesn't for some reason...

PDF files for the Blackfriars junction and Savoy Junction.

Sitting on the fence

So should you support the East-West Superhighway? Well, partially. The amount of space given to cycling here is great, and on some individual sections, I'll happily support completely. But there is just too much shitty junction design to give wholehearted support, and some sections where I have said no completely (Parliament Square and north of Hyde Park). So since TfL gives the option, I suggest people support partially. 

Too much hype tells TfL the job is done. It isn't, so don't give that impression.

TfL propose no worthwhile improvements. Tell them it's not good enough.

A few months ago I made a blog post with plans for Kings Cross. This was in response to a TfL consultation to improve the gyratory for cyclists. However, there was little improvements. Current cyclists may have benefited slightly from Advanced Stop Lines, but the plans were in no way attractive to anybody else.

A week or so ago, respondents to the consultations received an e-mail. Despite a large number of respondants citing safety concerns, TfL are going ahead anyway. However with one change. Semi-segregation will be used in places because:

[Semi-segregation] will allow cyclists to move onto the main carriageway and overtake stationary buses and taxis if necessary.
I think my reaction to this can be summed up in one GIF

This is not good enough. On Tuesday 12th August, come to Kings Cross Square for a ride around the gyratory, and tell TfL that their plans do nothing for cycling. There is a Facebook event page and a twitter feed.

Another design

As this junction was again brought to my attention via the e-mail TfL sent, I decided to give my design another go. When I made the original, I tried not to reduce traffic capacity, and I also didn't know about the wonderful simultaneous green junctions that exist in the Netherlands. So below, here is my second design for the Kings Cross gyratory.

My design, version 2
A simultaneous Green junction outside Kings Cross?

Design as a PDF (for zooming in without loss of quality)

My design isn't perfect. It has its faults and problems. However, there is one claim I will stand by, and that it is miles better than Advance Stop Lines and bits of paint on a busy gyratory. This area is the first impression of London for many people. Trains come to Kings Cross and St Pancras from Kent, the North of England, Scotland, Europe and beyond. A traffic sewer is not a good first impression for any city.

I don't want to London seen that way.

An e-mail I'd like to share

This is the response of the cabinet member at Kent County Council for Environment and Transport, David Brazier, to someone's objections to the scheme that, in my opinion, will lead to a large decline in the use of the bicycle as a mode of transport in Maidstone. I've started a petition to stop this, which explains more, and it would be great if you could sign it.

I've added a few emphasises, these are my own. Otherwise this e-mail is unedited:

Thank you for your emails regarding the recent outcome of the public inquiry into the application for the Powerhub site in St Peters Street, Maidstone.

The application was subject to assessment by the KCC Transportation & Development Team.  It was recognised that the reduction of the wide footway on the northern side of the St Peters Bridge would be a disadvantage of the development proposal.  However, this would be offset by the additional capacity for traffic that would be gained by widening the carriageway over the bridge to four lanes.

The width available for pedestrians and cyclists on the northern bridge would be reduced to 2.5 metres.  This is too narrow to maintain the existing segregated space, so pedestrians and cyclists would have to share this space.  KCC recognises that this is an important route across the river for cyclists, and that it connects to cycle routes on either side, however the numbers of cyclists using the bridge have been fairly low; generally in single figures during peak hours.

Therefore, on balance, KCC did not make an objection to the regeneration proposal for Baltic Wharf, as the overall impact on the highway network could be mitigated by the off-site works. We accept that these measures are not helpful to cyclists in a location where cycling on the actual carriageway of the gyratory would be extremely difficult.  However, my officers did not consider that we could sustain an objection to the development on these grounds.

KCC does not hold cyclists in contempt. I ride most days, wishing the traffic would go away, but accepting the realities of life. 

I appreciate that this may not be the response you had hoped for, however I hope that the information provided is useful and fully explains our position on this matter. 

So it turns out KCC does not hold cyclists in contempt.  They just give off that impression because they accept the realities of life.

Please sign the petition to stop this scheme going ahead. This could be any town, please don't let it be mine. Thank you.
