what were the merge instructions, if any?

if merge in turn he was wrong

if there were road closed indicators well before the point you ran into trouble you should probably have anticipated it (although he was still wrong to do what he did)

the concept of merging works when ALL parties play ball

unfortunately many seem to think merging is defined by barrelling down the outside (or inside) lane for as long as possible and then forcing someone to give way - usually accompanied by some bollox about making the best use of all available road space

otoh, if more people merged earlier it would probably result in smoother traffic flow

it only takes one person to refuse to do that (in the absence of merge in turn signs) and chaos often ensures

fwiw I believe all road closures should have use both lanes/merge in turn signs

You had to say something didn't you?? Couldn't just leave well alone. Muppet!

The queue started before the lane closure signs, there were roadworks signs IIRC but that was it. I was in the outside lane for a few hundred yards after the first sign and at the 'lane closed in 800 yds sign' (ie. the first indication of a lane closure), the truck swerved out, several cars had gone past him in front of me and I had no reason to suspect he'd decide to pull out at that point. Incidentally he did it just at the end of a slip road as a Golf was entering the traffic behind him, it was obvious to me that the Golf was about to move into lane 2 behind me as soon as I'd passed. If the Golf driver hadn't seen the truck swerve (ie. he was looking in his mirror for anything coming in lane 2) it could have been even nastier.

So pretty much at the point I was thinking I'd better look to slowing down to the speed of lane 1 (about 20mph, I was doing 30-40 on a trailing throttle), PC Truck Driver decides to become a rolling road block, closing the road 800yds before the obstruction. I'd say that constitutes DWDCAA, since apart from the obvious danger of deliberately pulling out in front of me and the Golf, he immediately moves the closure 800yds up the road and across a major junction.

what was it you were saying about abuse and getting personal?

 

The lanes merging is an interesting one; flow studies have shown that if everyone barrelled down the fast lane & merged zipper file before the end, it disrupts flow less than tailing back & merging too early into the creepy-crawly lane. It's counter-intuitive and people probably couldn't be trusted to do it out of ineptitude/road captaincy etc.

I'd be interested to see a study into d/c roundabout d/c left-turning; it may be the case that fast-laners turning left by going round the roundabout (thus allowing the left-laners to flow consistently unimpeded) might actually improve flow rates - dependent upon other roundabout feed volumes, I'd hypothesise.

 

Re para 1, as I said, it requires two to tango. Not going to happen at speed, at least not under my definition of merging (that's the one where no-one needs to brake, swerve, etc)

Re para 2, how could traffic be consistently unimpeded in the left lane if they have to give way to traffic coming from the right?

 

Read para 2 if it's dual carriageway all round the roundabout & in and out, it could work. Sort of like where there is a left filter lane to avoid the roundabout entirely for traffic turning left, only there's not a left filter lane to avoid the roundabout entirely for traffic turning left, sort of thing.

 

It works in Germany. "Reisverschluss" ie zip fastener. It is normal and observed making traffic flow freely.
The left lane would not be impeded any more than the right lane . One from the left then one from the right then one from the left etc etc.

 

Same in NL, don't know why all these simple things have to be so difficult in this country
