Have you ever heard of such a Light System ?

Question

Hi there, I've heard there is a new system applied on the sides of some roads which
controlls the lighteninig.At nights when there is no car entering into the road,this system
turns off the lights and whenever a car enters into the road from one of the slip roads,it
turns on the lights and keep them turned on for a certain time for example 2 or 3 minutes.
By this way it saves the energy.

Can you help me with finding more information about this system?
Best regards

Answer 1

Never heard of it but all lamp posts in the uk r fitted with photocells which detect light and turn on if there is none, so if u fit an infared sensor to one of these (which detects movement via heat) and a timer set on 2-3 minutes u would then have what u r talking about

Answer 2

Haven't heard this for roads, but I have seen it in industrial settings. At Ford, we have recently installed a lighting system that will turn out the lights if there is no one in the area, it is one of their new cost reduction ideas.

I see no reason that this same thought couldn't be applied ot the road system.

I never heard of such a thing, but it does sound logical.You may try a search on 'lighting' and then refine your search from there.As in 'Highway lighting' or 'Illumination'
