Traffic light problem in Golders Green

I find that difficult to believe. I don't think the lights at the junction of Bush Road and Leytonstone High Road have sensors, for example. they certainly don't have the obvious ones that sit on top of the lights (although they might have a loop in the road itself, I suppose). I don't think the traffic management at that site would be improved by them, either, so the only thing they would add is increased maintance costs, and more things to break, for no benefit. -- :wq |

No traffic lights on a public road, whether temporary or permanent, can be installed without sensors. Almost all permanent lights have sensor loops in the road surface. Only a few have the sensors on top of the traffic light that are universal in temporary installations. |

As Bruce says, most permanent lights have detector circuits embedded in the road surface. At that junction, Google Street View seems to show an anti-skid surface, which would have covered the tar lines indicating where the detectors are. No traffic lights on a public road, whether temporary or permanent, can be installed without sensors. What law or regulation specifies that? I'm not aware of one. Certainly it's normal to have sensors, but I thought that fixed-time signals were still legal. A Highways Agency press release from 2006 talks about a fixed time traffic light installation at York being upgraded, and Worcestershire County Council's site says that fixed time temporary lights need their written approval, so in both cases it seems that fixed time signals are not illegal. -- Richard J.

"Mike Bristow" wrote in message ... I find that difficult to believe. I don't think the lights at the junction of Bush Road and Leytonstone High Road have sensors, for example. Is it 'LEYTONSTONE HIGH RD / BUSH RD / TESCO SERVICE RD' ? There are input sensors for that junction although I'm not sure without looking further what type The junction in the OP's message is the same - no record of anything sensor wise - but there have been a few faults in the past 6 months. Mostley lamp's out and little things. |

Is it 'LEYTONSTONE HIGH RD / BUSH RD / TESCO SERVICE RD' ? Yes. And now I think about it, it's the tesco service road that probably needs the sensor. -- :wq |
