I must have sat there for nearly 5 minutes. There was about a 30 pause where no traffic was moving at all, then they changed. Why can't they change quickly and prompty like the normal light do?

Because the people who set them up do so in accordance with a book of rules rather than common sense and looking to see what actually happens. It is called "covering your a*se" so they do not get sued by people who disobey them and have an accident

Most temporary traffic lights have a movement detector above the lights. Unless the lights are set to a timer as well, if there is no movement then the lights don't change. If you approach the lights too slowly or you stop while they are turning yellow then they will think you are not there.
Did you know that all traffic lights have the effect of delaying traffic. Think how many times you are waiting at red and nothing ever passes on green. Get rid of traffic lights and congestion will disappear (with better junction marking etc).

It might be because the trigger to change the lights is a device that counts the number of cars....actually, sets of wheels, ....that have passed through in 1 direction. So if the traffic is light, it takes longer to reach the trigger.
Do you see what I mean? I haven't made it very clear.

Flash your head lights at them. They should have a sensor on top which picks up movement during the day and head lights at night.If no one is waiting at the other side they will change immediately.This also works on normal junction lights as they sit on red when a junction is not busy to change when a car approaches.

Tempory lights set up for bridge repairs and so on, are set on a timer .The pause is for all traffic to exit the bridge before the other side starts.

If you flash your headlights at it it may change quicker.
Alternatively (this has worked in some cases - I've tried it) approach the lights at around 30-35mph (make sure you can stop in time if they don't change though) because they sometimes go green to avoid a 'potential accident' caused by a 'potential red-light runner'

when you approach them and there is no other cars coming the other way flash your beams at them a few times, it makes them change a bit quicker because they think more than one car has approached and they are designed to reduce traffic so they will change.

How many times are you going to ask this question?
