Recipes: 0 Rep Power: 63 | All the time in the spring i see these boxes next to the road. with a cable stretching across the road. I'm thinking its something with the Dept. of Transportation but who knows. anyone know for certain? they annoy me, like i should behave and legal when i drive over it. there is one about a mile from my house, i'm loading my axe tonight and hacking that biatch up on my way to work. |

| IronMass Vip | I know, I hate those things. I think they're either counting cars or they're a more covert way of tracking speed.

Recipes: 0 Rep Power: 63 | i figured it could tell speed by the time between the front and rear wheels going over the cable. today i was behind a school bus. so i drove over it with the front wheels. then waited over it for 10 seconds. then hit the back wheels. should register something like a nice .0034 MPH |

Recipes: 0 Rep Power: 31 | They're used to calculate trends in road use (peak use times/ direction/ quietest times etc). Often useful if they're planning road works and they want to know if they can do work at night or they have to close the whole road etc

They can not record speed because not all cars have 2 sets (what about 18 wheelers?) and sometimes cars may not be in synch (first set of first car goes over, then first set of second car goes over). All they do is record how many sets of wheels went over and at what times, then they do all sorts of statistical analysis.
