I think timings of traffics lights (whilst not the absolute reason - that's down to the driver) are a factor.
Many lights were put up what 20, 30 years ago? Over that time, traffic has increased massively but the timings of those lights hasn't been revised to reflect this.
Two examples where revising the timing has worked:
Light near local Tescos would only go on to allow 3-4 cars through at a time. They then had some work to do and whilst they were at it, reprogrammed them so that not only do they now stay green for longer letting more cars through but also will "come out" of the algorithm if say, late at night and no one else is around, they'll turn green for you almost immediately as they detect your approach - no waiting at all .
Lights on way to work use to only let 3-4cars through, again, got revised a year ago and now let double that through at a time to allow for the increased traffic (longer time on green allows more cars through so there's less frustration which is why I assume some have the mentality of "having to get through" otherwise?).
One example of where it causes issues:
Road works have a temp light a few yards down from a permanent set also on the way to work. Unfortunately they've timed the temp set badly and it goes green when the slip road perm lights go green, so about 7-8 cars can get through. OTOH the main road part of the lights goes green when the temp lights (which has a long queue on it) is red.....so the main road goes green and only 1 car is let through at a time most times. This leads to a REALLY long queue on the main road stretching for 100yds and a 40min delay in a stretch of road that normally takes 20s to travel down....and yes, you guessed it, after long waits most drivers tend to zoom through those temp lights on amber and even reds because they've been waiting 40min to travel 100yds.
I simply avoid this altogether and have an alternate (4-5mile longer) route to work now which ends up halving my journey time, but I can see why people do it all the time on that particular section.
Even though responsibility does ultimately lie with the driver, you can cut down behaviour like this with intelligent timing that takes modern traffic into account imho. |
