Actually, after a visit to Disneyland where they really are experts at managing queues, whenever a long queue formed, disney employees urged the line to split up into two seperate lines which then moved twice as quick as everyone merged at the end instead of blocking each other to the detriment of the whole queue.
Also witnessed roadworks one day on the road from Aberdeen to Dundee, where the outside lane was blocked because of roadworks. The signs told everyone to use both lanes and to merge in turn where it split from two lanes to one, despite this, 75% of cars pulled into the inside lane forming a two mile long queue and a couple of a**holes decided to block the empty outside lane despite the signage instructing everyone to do the opposite. Upshot was the queue merged quickly at the pinch point, but further back where the a**holes were blocking the empty lane, everyone was stationary.
Not sure if folk realise that traffic management is a special skill that requires training courses and certificates, (which I have by the way), but to plan a job and put up signs instructing motorists how to negotiate a set of roadworks and have individuals deciding they will dictate what lanes are available is just nonsense. (Tried to be as polite as I could there to anyone who thinks they should dictate what lanes are open!)
