Junctions (and more U-turns)

Lahore has some of the most splendidly unwieldy junctions I've ever had the pleasure of being stuck in the middle of.  Imagine a crossroads between two 5-lane dual carriageways.  I say lanes, but that's not strictly accurate - it's actually a space for driving on approximately 5 vehicles wide, sometimes with some lane markings which are taken as loose suggestions.  At traffic lights, 7 or 8 queues of traffic will squeeze into the same 5-vehicle-wide space.

Anyway.  Now imagine that each of those dual carriageways has a service road on each side, giving access to the nearby buildings.  Oh, and each service road is bi-directional (though due to parked cars, usually only wide enough for one vehicle at a time).  The dual carriageways have traffic lights; the service roads don't necessarily, so people go when there's a gap, regardless of the vehicle:gap size ratio.

Also, when the traffic starts to move, one has to take into account the variety of different speeds, accelerations and turning circles of the various vehicles - a heavily-laden donkey cart being very different in manoeuvrability to a family on a motorbike, or an overflowing bus.

So as you approach the junction, you have at least an initial 5 lanes to choose from, followed by a choice of no less than 12 different potential exits, 3 of which - joy of joys! - would qualify as U-turns.

Needless to say, every change of the traffic light brings a new supply of chaos way beyond the capabilities of the single hapless policeman. Somehow though, it seems to work.
