What are the the the lampshade type boxes that hang from British motorway bridges used for? Quite often green!
Answers:
They are there for the 'traffic master scheme' they basically watch the amount of road traffic and general speed, then send data to a central computer system in Birmingham where traffic jams etc are sent to traffic report offices nationwide.
This is how local radio can tell you where traffic jams are!
Hope this helps.
