We have tried every imaginable way to keep our tube counter hoses from bouncing on the road. We had settled on wrapping nylon webbing around the tubes and nailing the webbing into the road. This has worked very well for us over the last few years. For a while we used duct tape (Ace Hardware brand worked best) to tape the tubes onto the road. Unfortunately, the duct tape wore out fast and usually came unstuck in a day or two. It works ok in residential areas with low speeds and low volumes. We aren't fans of mastic and other things the industry uses.
Ron in our office picked up a roll of Gorilla Tape at Home Depot a few weeks ago and used it to tape down a few tubes as a test. This stuff is amazing and we highly recommend it. We are on the sixth day of a seven day count at 9 locations and the tape looks like it is brand new (I hope I didn't just jinx us). Ditto for a bunch of 48 hour counts we did two weeks ago on high speed/high volume highways. We don't think it will work well on cold roads during the winter, but for the summer months we are sold on Gorilla Tape!
