Speed bumps for cyclists

Islington council has studded a path with a series of 14 mini bumps, aimed to stop cyclists from pedalling too fast.

I wonder who decided on 14 :rolleyes:

Bunny hop training ... excellent.

I'd like to see granny and her motored car/wheelchair thingy bunny hopping the bumps.

A drooling halfwit, 28, who lives in Angel, north London, said she thought the alternative path to get back to the main road was dangerous and people could easily fall off the bikes.

She added: "The windy path next to the road to the bumps is dangerous, especially at night, because there is no light sometimes I'm scared I might fall in the canal.

If it was Ireland, they'd paint a white line down the middle of it.

Such ramps would make the laneway effective unusable for the majority of commuting cyclists. Even if they have the skill, it's pretty hard to bunny-hop at a half decent speed while carrying a load on your panniers.

While shared cycle lanes shared with pedestrian foot-paths don't work as well as they could or should, I think that would be a much better solution for this situation. If there's enough traffic, users tend to learn what the markings for. Having said that the only time I've seen this work is the coast road out to Howth but I'm hopeful that it just needs time for people to gradually learn what the markings on the paths are for.

They've already piloted it on the royal canal near Broombridge

"Before they were put in place they would just come whizzing down the road and one of my grandchildren even got knocked down by one."

Im willing to bet that the kid suddendly bolted with a sudden change of direction in front of the cyclist, that said if your using a...(what? laneway? path? which is it?) then you dont go flying down it taking the piss like :rolleyes:

another case of one idjut ruining it for everyone

Only time it works is when the sun is in. On a sunny day, the idiots spill everywhere.

Sorry, I forgot where I was for a second. I'll use footnotes in future.

Speed bumps for cyclists will do the same as they did for cars - encourage take up of full suspension mountain bikes, the SUV of urban cycling.

From the photo, it looks like they've used the cheapest type of speed bump on the market. Anyone who has cycled into Trinity College via the Lincoln Place gate will be familiar with them, and they're nasty.

There are better ways to calm cycle speeds than this, which don't unduly inconvenience either cyclists or pedestrians- humps can be designed with different sinusoidal profiles depending on the intended design speed for the route, i.e. at the design speed, they feel like gentle undulations, but at higher speeds they feel quite uncomfortable.

Edit: p.30, fig. 5.3 in this TfL document, if you're really curious.

Sinusoidal? Sounds expensive. How about this?

At least they've done a thorough job. Not like the clown who decided to put rumble strips on the cycle lane adjacent to the foot path on the N11 as you go towards the Loughlinstown roundabout. You therefore have a choice to cycle on the nice smooth footpath or go bump..bump..bump..bump.. along the cycle path. I've never seen anyone use the cycle path.

I've noticed parallel yellow traverse markings on the very narrow facilities in the Sandyford Industrial Estate on the way out of the estate, heading towards the Upper Kilmacud Road.

Are these meant to be rumble strips? They occur as the cycle track approaches a bus stop, so I assume they're meant to make cyclists slow down.

Are they the ones that run with the direction of travel, rather than across it?

Across. That is, your wheel is perpendicular to the yellow stripe as you travel.

okay. On the N11 (IIRC), there's a bunch that are parallel to your wheel, so they fail at being rumble strips. Not too sure if they're meant to be markers, or just incorrectly installed.

I should take a photo the next time I see them. I'm assuming that they're meant to slow cyclists down anyway. They're very close together and traverse, as I said, so they probably would be somewhat unpleasant to cycle over, and they're just before the point where you'd expect pedestrians alighting from the bus to blithely wander over.

ive a kana dawg delug full susser, she would love this laneway, i dont know how ppl cycle around dublin with slicks and a ridget frame, i love roads that are in bits, more fun for me, woo air time
