And who instigated that ?
Local council were desperate to attract major business. Arla came along with a seemingly blank cheque book so local council gave them all they wanted in return for Arls paying for some road 'improvements'.
The lights are designed to speed traffic down a main route then off onto a 'ring road' (this junction is the only place where this is signed as such.
All Arla stuff coming to the plant has to come via this ring road (even though it adds miles). So everything coming along the road gets a lovely, long green light (left turn).
Of course, they also send the same amount of stuff back out, so it all has to turn right - and the only way to keep it moving is for them to have a long green light - which means we get the 4s light.
Prior to these lights, everything moved, albeit slowly around some mini roundabouts, at least with these, anything turning right meant they stopped oncoming traffic so you could get out to turn left. Not perfect but it worked well. Since these lights, we now see miles of traffic queues - at peak times, people sit in the junction. People also jump reds as they have been waiting so long.
Even though the road has a huge keep clear box where it meets my estate, I often have problems getting out as idiots tend to sit in the box - and despite numerous complaints to local dignitaries & police, nobody gives a crap. So now, I have to set out 10 minutes earlier & wait in a long queue just to get out of my estate - constant flow of nose to tail traffic coming by - except for the 5s of red light, whereupon there's a constant flow of traffic coming past the other way!
