Anyhow, I'd like to help them get a hold of the pot-hole problem.
At left is the signature of the "braille" on the center of the road by my house when driven over at 40 mph. You can easily pick out the regular peaks in the plot caused by each little braille bit. I hope to get things calibrated so that I can tell the difference between "braille" and actual pot-holes. The first order approach is simply to check the direction of the acceleration. Pot-holes are holes and road "braille" is sets of bumps. Thus, the initial acceleration due to the two should differ in sign.
