Re: Bus controlled traffic lights

As Pete Owen has pointed out the object is to get the bus running to schedule, preferably at 'line speed' not to give it priority in the abstract. In principle average bus speeds will be higher than the average of the general traffic flow, which could also be raised on the bus route. This seems to h...

Re: Bus controlled traffic lights

I, the OP, also tend not to bother overtaking a bus, because I know it will be behind me very shortly. Sometimes this does not work. I hover, it stops for longer than I expect, I decide to pass, do so, it catches me up, overtakes and stops again, or similar. But this is on a minor suburban through r...

Re: Bus controlled traffic lights

Indeed, a +1 for anyone who does not wish to see their bus sail by early and before they get to the stop. The relevance of this does obviously depend on the frequency and whether the buses can be regarded as running to a timetable. In Bristol, where suburban services can be about half hourly you do ...

Re: Bus controlled traffic lights

'We' are not letting go of bus lanes, but taking them over, remember, this is a cycling group, I think. The point is that the signals would be optimised to blow the whole half mile congestion plug through with the bus. On a 20 mph road this would take 90 s after which some other optimisation would r...

Re: Bus controlled traffic lights

The ORR list will be useful, I need to work through it, but a first flick through the references for the Manchester system suggests links concerned with the public interface (wonders thereof) rather than the way the system operates. I have been told that the Manchester trams do obtain priority over ...

Bus controlled traffic lights

I would welcome references to bus or tram controlled traffic lights, both system (1) and equipment level, particularly manufacturer's data or official descriptions of systems, although histories would also be useful (2). I am thinking of things like refs (1) and (2) but for as many examples as possi...

Re: European importers: Are they at it?

my comment re QA clearly hasn't registered. ... ... All the big manufacturers have staff onsite at their subcontractors and their main job is to make sure that the QA is up to snuff. If you buy direct from the manufacturer it might be just as good as something else but then again it might not be su...

Re: E-bikes: depressing or what?

.... If you really think you need electric bikes for 18 year olds on flat city streets, then, yes, that is depressing. I often come across this idea that electric bikes are a panacea because they take the effort out of cycling, as though that is a deal breaker and physical effort the real downside ...

Re: Advice on crossing crossroads

.... It's still better than trying to obey the motor traffic bits of the highway code: wearing glasses is usually a good idea for cyclists, but HC discourages it for drivers. Can you even get seatbelts for a safety bicycle? And obviously, using motorways is a no-no. 'Driving' (1) provides comprehen...

Re: Advice on crossing crossroads

Re: Woman struck by hit-and-run cyclist in Dalston dies - BBC

[... Neither cyclist looks to be going that fast to me. As for not pedalling, I frequently find myself stopping because due to the extra weight ebikes can roll for Britain. In the circumstances shown, I may well stop pedalling as I find myself catching up with a cyclist in front of me. Assuming the...

Re: Car Avoids Something In Road.

Badger carcasses on the road have always been common round here, where there are several badgers sets and plenty of evidence of them passing through gardens. Having seen a live one when nearly back home, driving a car, about midnight, I suspect road deaths are partly because they are slower than fox...

Re: How Do You Exit A Roundabout. Incident Two.

Using the LH lane is both incorrect and dangerous - the TI near me is marked on one approach as LH+ S and the adjacent exit has a collision almost every day - the other approaches are marked LH only and don't have the issue. The OP appears to have taken the route intended by the designers, and also...
