So what they are actually comparing is a very specific arrangements of segregation (one-way track bent away from the road) to other segregated layouts then simply assuming unsegregated roads correspond to whichever...

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...

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...

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 ...

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.....

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...

Vorpal wrote:But that is a traffic flow improvement that favours buses, rather than priority.

Ah OK. I think I see what you mean. But it is still potentially a good thing to have, yes?

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...

This may be of interest, especially the eighth paragraph:

David Gardiner of Laid Back Bikes is trying a 1*12 setup on his demo Nazca Fuego. You could ask him how it is going. I've mentioned this before, but I think it is nice to avoid really small chainrings, as they seem to give a spongy feel to the drivetrain. I think this is mostly due to frame flex, bu...

Hello all There is a tool called JBike6, which allows the stability of bicycles to be analysed. There are several simplifications, such as no friction in headset or tyres, infinitely narrow tyres etc. Nevertheless, if you only want to compare one result from the program to another, I think that is O...

Hello Pete One of the odder handling differences I've come across is changing the bars on an overseat steering 'bent from aero to tiller style. In either case the bike's geometry is fundamentally the same, and with no weight on the bars and seating position pretty much the same (arms excepted) there...

... for one particular niche of the sport. To some people cycling is a sport, to others it is primarily a mode of transport. I suspect this is part of the reason behind the disagreement. You can argue on the head of a pin (and many do) about the usefulness of such developments, but you can't easily...

Marketing and lifestyle images have always been with us. ... Which helps no one I think that grumpy skepticism serves a very useful purpose! There are a whole host of marketing departments out there trying to convince people to buy their new stuff. This needs to be counterbalanced by an army of bea...

I'm very pleased that this discussion has digressed into recumbents! :) I'm pretty sure the difference in aerodynamic drag between a typical racing bike and a sporty recumbent (with the seat reclined a long way back) is an awful lot more than the difference that even the best wheels can make! Also, ...
