What are those black rubber hoses for any way?

Any one ever notice that sometimes there are these things - looks like black rubber hoses - laying across a road or highway exit? You drive over them and you feel a little bump. Lately I have seen lots of them along many exits off the highway south of Boston. What are they there for?

I believe they are to count the number of cars passing over them ... for traffic studies. At least that's what I've always thought.

That is what my educated guess is too - seems logical. It was either that or they put them down to annoy me.

Do you think if I kept backing up and driving over and over them I would screw the whole stats up?

The devices are pneumatic. A car drives over the hose and air pressure cause the counter to record a vehicle. I had a friend who had an MG (this was in the 60's) who used to go around and lift the back end over the hose thinking it would record one half a car. I'm not certain that works.

I think it would be a waste of time (and dangerous) as trucks passing over them would record one and a half vehicles.

I was thinking that once too Shewolfnm, but then I realized I would have had several speeding tickets as a result.

Then I thought - maybe they were just left there because of construction or something (there is always some sort of construction going on. But this is the first time I noticed several in once area - all on exit ramps - so I suspected that there was more to it than just random hoses left around.

Laughing That's what we were always told growing up.

Then, a friend of mine brought up how it would be impossible to measure the speed of a car by measuring the time between the front tires and the back tires of a car going 65 plus mph.

When I was a new driver though, I would always slow down if I saw one. Like as if there were a cop sitting there measuring it.

i was thinking the same thing

not that they can identify the specific car that was going by at that speed...
but.. it was a way to find the places in town that had the MOST speeders and with in the next 24 hours, i thought, there would be a cop where the black hose was..

Indeed older speed measuring devices used the black hoses but with the advent of radar they were phased out. They are used now for counting vehicles.

I am bringing this back as in my town there has shown up a plethora of these black hoses. I am now driving back and forth and over and over on these hoses just to mess up the counting.

So why do you think all of a sudden there are several located throughout my town? What are they planning? Hopefully it is good spending for my tax money. Maybe I will call town hall to find out what is happening.

@Linkat,
They often have to do with determining where traffic lights will be put in.

This^ or trying to determine speed limit changes in a given area.

@ehBeth,
It would make sense, but they are in random areas - not at street crossings where you would expect potential lights - two are nearby the schools (high school and middle school) the other is on a high traffic area but just random in the middle of the route - not at any sort of intersection - not too far though from a busy intersection that already has lights.

@Linkat,
The school examples just helps my speed checking theory.

@tsarstepan,
true - we had some a while ago that resulted in our block being turned into a one-way (just our block, not our street)

also had some that resulted in a flashing light going in at the top of the street - two blocks over they got a new set of lights

@tsarstepan,
Its funny they do not have any school zone signs --- I always found that odd. And the middle school is on a very busy highly traffic road - granted they have a long road into the school itself, but the road has a fairly high speed limit.
