Cyclist who broke six ribs on CS6 says it is not obvious white line is a raised kerb

New stretch of CS6 opened last month with vertical kerbs separating cyclists from vehicular traffic

A cyclist who broke six ribs after a crash on London’s Cycle Superhighway 6 (CS6) says it is not obvious that the lane dividers on a recently opened stretch are actually raised.

The London Evening Standard reports that Max Hotopf fell after hitting the painted 10cm high ridge that separates cyclists from vehicles in Farringdon Road, just north of the Clerkenwell Road junction.

Transport for London (TfL) said the accident was the first involving the raised white line to be reported to them.

Hotopf said: “I have been cycling on London’s roads for 40 years so I am very experienced. It looked like a normal white line. There was nothing to suggest it was raised. I hit it and went flying and now I have these injuries.

“This is badly thought out and TfL need to come up with some answers. They need to put up warning signs. It’s so easy not to spot the danger.”

This stretch of the cycle superhighway opened last month and campaigners had suggested the vertical-sided kerbs could prove dangerous.

Hotopf added: “It’s only a matter of time before someone else is seriously hurt. They need to sort it out — the cycle lane is supposed to keep riders safe, not injure them.”

TfL has launched an investigation and said: “Safety is our top priority and we always closely monitor new cycle lanes.”

Why is it that the Dutch have already solved this problem?

It is depressing that some idiot thought this was OK, and it even passed a safety audit. It is easy to see how the accident occurred. I once hit a full sized kerb and came off. It was night and my bike lamp made it look flat. It is fortunate that Max Hotopf didn't fall right into the carriageway and get run over by a passing motor vehicle.

The use of battered kerbs (ones with 45 degree angle) should be an obvious choice. Sadly this stretch of CS6 now needs to be reconstructed at huge expense to the taxpayer when a more appropriate kerb profile would have been cost neutral at the time of construction. And all because cyclists were ignored when they pointed out the hazard.

I would personally vote for more curbs like this. Far too many incidents of being nearly run off the road when cycling in the cycle lane because of drivers trying to squeeze past other drivers waiting to turn off the road. The major problem with segregated bike lanes is that they don’t get cleaned like the road does meaning that they are often obsticle course of general rubbish along with broken glass bottles etc.

In the Netherlands they apparently have sloped kerbs to prevent this:

A rumble strip next to this kerb would solve the problem

No it wouldn't. The solution is to remove the needless hazard.

Who are these fckukwits who design and implement "cycling infrastructure"?! Presumably they are at least reasonably intelligent to be in such positions of responsibility, so how can they be such..... fcukwits?

Good feature badly implemented.

They use these in Copenhagen with great success.  They were already built like that, when I started cycling there for a while in the 90ties, well before the big hype of Copenhagenizing etc. Since they are so common, nobody really seems to have a problem with it - given that the bike paths are so wide, that you never need to come close to that line (which is not painted at all in Cph. The kerb to your left (the car lane) looks like the kerb to your right (pedestrian path). So you know what to expect on both sides.   

Problem seems to be, you have to know about this.

exactly - a major problem with much cycling infrastructure is that its not obvious or consistent - infrastructure for motorised vehicles is generally uniform and as said above is readily changed when it doesn't work but cyclists are expected to just deal with it

In programming this is known as the "Law of least surprise".

Quote:

A typical formulation of the principle, from 1984, is: "If a necessary feature has a high astonishment factor, it may be necessary to redesign the feature."

In general engineering design contexts, the principle means that a component of a system should behave in a way that users expect it to behave; that is, users should not be astonished by its behavior.

Road engineers are generally completely oblivious to this principle.

OK it isn't perfect, but it's much better than the pot holes mess that most of us have to deal with. At least TFL are doing something to try and make the cyclist's lot a safer one.

Brighton had this same issue with the Vogue Gyratory cycle lane 3-4 years ago.

The short cycle track TfL installed at the junction of Old Street and Great Eastern Street has 45 degree kerbs, why are they going back on that as a standard?

If the recommended safe cyclist overtaking clearance is being touted as 1.5m, perhaps the raised kerbs should be 1.5m wide so that the segregated cycle lane is safe for those who use it? Assuming this is "purpose-built" infrastructure, why the need for a sharp edge on the cyclist side?

If this is the case and the council were warned then I think a trip to the no fault injury lawyers would be profitable.

I'm a bit confused as to how you could miss a standard height kerb let alone mistake it for a painted line

Perhaps it has something to do with a history of kerbs being on the left, and the expectation that that is where the hazard lies.

Shouldn't dedicated cycle infrastructure be designed so as to reduce the level of stress involved in cylcing?  Instead of adding to the amount of mental work required?

 

I don't get why you are trying to defend this.  When roads have hazards for motorists, they usually get removed or ameliorated.  Why else do we have all those centre-line barriers and crash barriers on bends, etc?  Here they seem to have specifically put an extra one in, simply due to the usual local authority inability to listen to anyone or take advice.

So, put simply, you want everyone else to take responsibility for your safety while you ride along smelling the flowers. 

 

Just to be extra specially clear, I'm not defending this, just saying look where you're going, but btw it isn't dangerous

a cyclist was killed on London Bridge about 4 years ago after coming to grief on the kerb-height central reservation. https://www.standard.co.uk/news/london/cyclist-killed-in-london-bridge-c...

While it's true that people are responsible for their own safety, it's also true that civil engineers and the organisations that hire them have a professional responsibility and an ethical duty to design foreseeable and avoidable hazards out of their constructions. Part of being responsible for our own safety is acting to make them live up to their responsibilities. They are our servants.

What a mad comment.   Not really thought-through, was it?

 

Let's dig a 10 foot hole directly outside your front door.  To do otherwise would mean everyone else taking repsonsibiltity for your safety., right?

No we just want infrastructure not to be designed as an obstacle course when you are cycling in the lane it will be very hard to see the line has any height as you will be looking down onto it.

Let's compare with speed humps which are painted with arrows to make them as easy to see as possible despite the intention for drivers to drive slowly along the entire road and the fact they are less likely to cause a crash.

Busy with other cyclists, glare from the sun or from wet roads or car headlights, darkness/poorly lit, the angle you look at it (or don't look at it!), the expectation of what would be there (seeing as most "bike lanes" are just paint it's not unreasonable to assume that this would be as well).

If it wasn't for the political minefield, London wouldn't be difficult to convert to truly world class cycling infrastructure. Problem is it's being done piecemeal with weak-willed leaders who bow to the slightest bit of vocal nimbyism and backlash, water down the scheme until it's a fraction what it could or should have been and then build it to the lowest possible cost.

Square-edged kerbs are much cheaper than kerbs with a chamfered edge.

Who did the safety audit?  and why didn't it prevent this glaringly obvious hazard?

it's clearly there to keep the cyclists in rather than keep motor vehicles out. It needs to be wider to keep motor vehicles at a safe overtaking distance.
