Has anyone seen those black "ropes" put across roads? Know what I mean?

They are laying on the road and you run over them...there are usually two several blocks away from each other...

What are they for? To check speed, or how many cars are traveling down the road or what...

They look plastic to me....just

  • My husband says they are counting cars and they use that data to help plan road construction (adding lanes), traffic lights, how rapidly the road need to be repaired, etc.

  • To count how many cars travel a road. Usually for when construction is scheduled to plan detours down alternative roads

  • I agree it is to count cars. They use to have people out there counting cars before the black cords.

  • I know what you're meaning but I never knew or asked. I just figured it was counting cars

  • Wow, and I always thought it was to determine whether or not they needed to either set up a speed trap or put up one of those signs that tells you how fast you're going.... because usually, that's what comes a few days after the "ropes"

  • I think its both , to count cars and see how fast they are going. Usually a speed trap appears shortly after one of them.

  • Christina807's husband is exactly right. My neighbor works for the DOT (Department of Transportation) and said the same thing.
