what is this road sign?
hi all
can any one help answer a question that has gone round our shop over the last few weeks that no one can answer.
what is this sign for?
it approx 2ft x 1ft portrait road sign with what looks like a bar code on it in silver on a aluminum backing, they are set parallel to the road unlike a normal sign that would be at right angles.
its now bugging us as no one seems to know what they are for. i don’t have a picture of one as by the time i have seen one its to hard to go back to take a picture, but we have seen the all over the country.
help please before we go mad!

is the sign dead flat, or does it have something behind it ? small laser box possibly ? it may possibly be used for either measuring traffic numbers, lorries if it’s higher up, or more likely, measuring to see if the verge is slipping, they line the lines (barcodes) up opposite each other, and then check again every so often to see if they’re still lined up of out of original true, look for big cracks in the road, that might be a giveaway,
years back, my dad used to work for a ‘soil instruments’ company, installing all kinds of weird and wonderful jiggery pokery under bridge supports, under new roads, beside roads, constructions sites etc, all designed to measure movement of some kind or another !

These signs are used for highway maintenance, they send trucks around with masses of sensors on board , presumably to check the condition of the roads etc. and it is quite simply a bar code they read as they pass to identify the road they are surveying.
