Programming of Temp Traffic Lights - BobbyG
Council are replacing the Traffic Lights with new TLs along a route I drive.

Both of these are at crossroads. When the normal lights were in situ, opposite sides of the crossroads had green lights at the same time .

During these works, there are now temporary traffic lights in place and they now have changed the sequence so that only one direction has green light at any one time. This is causing huge tailbacks.

Before I phone the roads dept to complain, can anyone confirm if temp traffic lights can be programmed to give green lights to more than one direction at at time. Whilst sitting in the traffic jam tonight it dawned on me that I don't think I have ever seen this happen.

Any takers?

In London they seem to detatch the old lights and mount them on temp posts (usually in a concrete filled oil drum) then leave them running on their original programme while the new set up is installed round them.

That would make too much sense for up here! No, its definitely the temporary type you get with roadworks that they are using in this instance.

Pretty sure they can change the sequence, timings etc. Often the workmen pick up the lights and forget to alter the timings and sequence to reflect the traffic conditions of the road. Just give the highway team at your local authority a call and they should be able to sort it.

They do it deliberately. The more delays they can cause during the roadworks, the more grateful everyone feels after the "improvements" are in place.

The same thing is happening along the A4 in Slough. Huge tailbacks because only 1 direction of traffic flows rather than 2.

The interesting thing is that before they instaled the temp traffic lights, the main lights were 'down' for a couple fo days. This meant that NO traffic lights were at the junction for a short while. In this short time, no queues were there as everybody went through the junction at a safe speed and gave way to appropriate traffic.

Up went the temp traffic lights and the queues then formed. Go figure.
