As a general rule, cycleways in urban areas in the Netherlands are marked distinctively. If they are two-way, they will have a dashed centre line. If they are one-way, that centre line will obviously be absent.
I think this is actually tremendously important – it lets you know exactly what to expect when you are cycling along a piece of infrastructure. You will know, from looking at it, whether to expect ‘traffic’ coming in an opposing direction. It also tells other people navigating these environments exactly what to expect – a dashed centre line will tell people walking that they should expect cycles from two directions. And the same is true for drivers, when they cross this infrastructure.
Unfortunately (and it is early days) we don’t seem to have the same level of consistency in Britain, as yet. While plenty of new two-way cycleways do have clear centre line markings –
Others don’t – even the on the same ‘route’.
I think this can cause problems for pedestrians in particular. The photograph above just looks like a one-way stretch of path, heading away from the camera. There isn’t anything to tell someone wanting to cross to expect cycling in an ‘unconventional’ direction, on the right hand side of the road. I suspect this lies behind the small number of minor collisions between people walking and cycling on this stretch of road – people are crossing without looking in the ‘wrong’ direction. This has nearly happened to me on a few occasions – I can clearly see pedestrians not looking for me as I approach.
A centre line marking would make it clear that this is two-way ‘road’, for cycles, and make it more likely that people will look in both directions. It won’t eliminate this inherent problem with two-way cycleways, but it will at least mitigate it.
I think the lack of centre line marking is also a problem for people cycling. There are no centre line markings in Blackfriars underpass, despite this being one of the narrower sections of new two-way cycling infrastructure in London, narrow enough to resemble a one-way cycleway.
This lack of marking may have been a contributory factor in the largest (and most serious) pile-up seen so far on new cycling infrastructure, captured on video by 4ChordsNoNet.
Just before the collision occurs we can see people overtaking well over onto the ‘wrong’ side of the cycleway. Because there is no centre line, there is no clear, constant visual reminder that, if you are overtaking, you may well be in a section of ‘cycle road’ where you should expect oncoming cycle traffic, which will result in complacency and the kind of incident seen in the video above; especially when people are cycling in the ‘conventional’ direction, on the left hand side of the road.
I suspect consistent centre line marking will also mitigate the problems experienced by people cycling against heavy tidal flow, where (without a centre line) people tend to spill well across the cycleway in the dominant direction. This can be intimidating for people heading in the opposite direction. A centre line would reduce this problem – people can still cross it to overtake, of course, but they would be reminded more clearly that they are going against the flow, rather than simply claiming more space for their direction of flow.
It’s not clear to me why centre lines are absent on so much of London’s new cycle infrastructure, but I think it’s an obvious mistake that is resulting in problems of understanding and (at the moment) minor collisions. The good news is that it would be very cheap and easy to remedy!
