Why are there no lanes as you approach a toll plaza?

    Just wondering here... on busier days it gets quite dangerous approaching.

    Coming out of course is great crack as you get the "airport runway" feel, but of course still a bit messy as you jostle for position when the lanes reappear.

    Is there a school of thought on this? I know its not exclusively an irish thing either - i know the Severn Bridge in the UK is similar design.

    How would you do it? Take the M4, going from two lanes to eight or nine?

    Don't really see the point either. It would only makes sense if every gate was open 24/7, and the lanes were marked with plastic bollards.

    The school of thought is that in the absence of defined markings, drivers tend to be much more observant of what is going on around them (no "tunnel vision" effect) and it acts to reduce collisions.

    They tried this principle in an entire town in the Netherlands somewhere. Not sure how successful or otherwise it was.

    In several towns, and it's been pretty successful:
    Netherlands
    Makkinga, a town in the Netherlands, has no road markings and no signs giving an order or direction signs visible in the streets. There is a traffic sign at the entrance to the town which reads "Verkeersbordvrij", meaning "free of traffic signs". Parking meters and stopping restrictions are also absent.[4] Drachten is another pioneer town for such schemes. Accident figures at one junction where traffic lights were removed have dropped from thirty-six in the four years prior to the introduction of the scheme to two in the two years following it.[17] Only three of the original fifteen sets of traffic lights remain. Tailbacks (traffic jams) are now almost unheard of at the town's main junction, which handles about 22,000 cars a day.[18] See also Woonerf

    Have a look HERE south of Paris on the A6. It's not too bad when very busy or light, but the 'ducking and diving' at speed to get to a free booth when the traffic is moderate has to be seen to be believed :eek:. It's nine lanes (booths) wide from a three lane m'way, each side.
