Cables Across the Road???

I’ve noticed, on several occasions, cables going across
the road.  Usually there is one cable that stretches
across the entire road, and one that stretches about
half way.  They are both connected to some kind of
box at one end, and they are parallel to each other
(about 6 inches apart).  What the hell are these things
for?

My only guess is that are used by traffic engineers
to collect data.

Anyone have any idea?

    That’s exactly what they are. They are used for traffic studies, to
    count cars.

    A lot of them are pressurised hoses rather than cables – the box
    counts pulses and hence the number of vehicles passing. They work like the
    attendant bell in desert petrol (gas) stations in 60′s American films.

    Hmmphh.  They still use those things, and not only in the desert…

    Next time you see those cables, drive back and forth over the cables
    several times to mess up their counting! <grinning evilly>

    Nooooooooooo! Many times they are counting vehicles in order to determine
    if there is sufficient traffic to warrant a STOP sign! There are legal
    requirements for a municipality to erect (Beavis: "Huh, Huh, Huh. He said ‘Erect!’")
    a stop sign or other traffic control device, although that never seems to
    stop my town from putting up the damn thing on every street corner. Arghhh.

    Don’t give them the ammo they need! :)

    Actually, I recall a local story about a town that was actually REFUSED a stop
    sign at an intersection where a girl was killed while crossing the street. They
    refused on the basis of an actual study conducted by the DOT. Of course
    the local folk said "We don’t care what the facts say, we want a stop sign
    anyway!". Not to make light of a tragic accident, but why is it that everytime
    an accident occurs due to negligence on someones’ part, the only reaction is to
    put up another stop sign?

            Such that the box knows how many cars pass per say light change.
    How fast they are going. Then it’s stat.

    Speaking of counting cars, does any other city use HUMAN car counters?

    I’ve only seen them in Ottawa during the summer, where they get
    university/college students to count coars during the day. On busy roads,
    you can sometimes find 4 of them at an intersection.

    Just curious as my housemate and several other people I know used to do that
    in the summer.

    If there is two of them and they are about 2 metres (6-7 ft) apart,
    then they may be a speed trap!  I don’t know if they are still used
    over there, but here in New Zealand you see them once in a while.
    Easily identified by the cop parked on the side of the road 500 metres
    further down :-)
