Re: the art of bicycle folding/packing for transport; modifications for rinko etc.

The Rinko idea seems quite nice, although I'm not sure about regularly taking the headset apart. I feel like a headset, especially a threaded one, is the kind of thing you want to get set right, and then leave alone as much as possible? I thought this video might be of interest to some (it's a foldi...

Re: Painted cycle lanes may make roads more dangerous for bike riders

Well, I can see that there are some potential issues with surveys. However, if we reject all surveys out of hand, what are we left with? How do we find out what the main barriers to more cycling are? Intuition? Anecdote? Poking a finger in the air? Surely the thing to do is to look at each study in ...

Re: Painted cycle lanes may make roads more dangerous for bike riders

Certainly the car has replaced a bicycle as the main mode of travel to work, shop or pleasure ground. This is due to many reasons - many. Those reasons may include "lack of cycling infrastructure" but that will be a teen-weeny reason compared to ... There may indeed be many different reas...

Re: Painted cycle lanes may make roads more dangerous for bike riders

Quite - so exactly what I said. No, not exactly! There is an important distinction between ...assuming unsegregated roads correspond to whichever performs worse. and what Schepers et al (2011) actually did. If you have another look at my post then this will hopefully become clear. To be clear, I'm ...

Re: Painted cycle lanes may make roads more dangerous for bike riders

Cars in London (and other urban spots) cause high levels of pollution, as well as squashing and maiming many pedestrians, cylists and, of course, the car drivers themselves. A superhighway does very little if it just makes you feel a bit safer - especially if (like the pedestrians) you are still su...

Re: Painted cycle lanes may make roads more dangerous for bike riders

infrastructure doesn't cause conflicts at junctions, Of course it does (again assuming that you use "infrastructure" to mean "segregation" for the purpose of argument) by its very nature. Conflicts between cycles going straight on and vehicles turning into side roads exist alrea...

Re: Painted cycle lanes may make roads more dangerous for bike riders

As to London and it's superhighways ..... Perhaps they did make cycling marginally safer - although there are still regular deaths and maimings. Their purpose is not only to make cycling safer, it is also to make it more pleasant. When I am cycling in London, when I get onto one of the newer "...

Re: Painted cycle lanes may make roads more dangerous for bike riders

I think it was clear from my comments that I had read more than the abstract, That's good. Just wanted to check we were talking about the same paper. I emailed Paul Schepers, and the reference to Schepers et al (2013) is indeed a typo, it should be Schepers et al (2011). This provides the reason fo...

Re: Painted cycle lanes may make roads more dangerous for bike riders

Mjr prefers a separate infrastructure for cycling. This seems to avoid the fundamental issue (dangerous driving) and is likely to be far more expensive than more traffic police and prosecutions etc.. It won't save pedestrians or motorists from the ongoing carnage. In New York they found that when t...

Re: Painted cycle lanes may make roads more dangerous for bike riders

Hello Vorpal Did you read the whole paper or just the abstract? Are you referring to the 2017 paper by Schepers et al or the 2013 one? The 2017 paper is a general overview of the various factors which contribute to cycling safety in the Netherlands, including cycle paths. I believe the reference to ...

Re: Painted cycle lanes may make roads more dangerous for bike riders

Hello Axle Knutt Why is there no research from the last 20 years in your list? How did you come up with the list? Did you assess the reports and papers for quality? (e.g. peer review, sample size, relevance, methods used etc.). I think some relevant research may have been done in the last 20 years.....

Re: Bus controlled traffic lights

What about other vehicles in the bus lane? Taxis, motorcycles, and of course pedal cycles, might be others too in some places. And what about junctions without traffic lights? Either the bus lane becomes a left-turn lane just before every side road and then starts again, or it needs to be continuou...

Re: Bus controlled traffic lights

Basically it is not possible to provide priority for bus traffic without bus lanes. In order to gain priority, the buses need to be able to overtake the queue and for that they need a separate lane. It really is that simple. I'm not sure about that. I recall reading a comment by someone who used to...
