Glasgow Traffic Lights
When traffic lights were first introduced, they worked purely on a timer basis, even if there was no traffic coming the other way.
As they developed, we saw the introduction of pneumatic sensor strips in the road which were then replaced with induction loops to detect traffic and keep the traffic flowing as best as possible (Anti-car Ken Livingstone’s meddling in London aside).
However, whenever I go to Glasgow, I find myself regularly sat at a red light for long periods, when there is no other traffic (road or pedestrian) at the junction. Even in the middle of the night. They don’t seem to take the actual amount of traffic into account.
Now this is a serious question, and maybe someone can clarify the situation – do the Glasgow traffic lights still operate on a timed only basis?
