Pothole Detection System

When a vehicle hits a pothole, a fair amount of energy must be transmitted from the vehicle to the ground surrounding the offending crater.

Using an appropriately spaced array of vibration sensors buried below the road bed, the location of the pothole could be determined by triangulation using the timing of the energy imparting "event" as sensed by three or more proximate sensors. Pothole formation can be discriminated from "noise" by various characterstics, such as amplitude of the detected event and whether or not an event is triangulated to the same location repeatedly.

I haven't worked out the physical connection of the sensors but they would be interfaced to a computer located in a nearby traffic signal control box. The pothole severity/location would be calculated and the information would be transmitted back to the appropriate roadway maintenance authorities via the network that is already in place to communicate with traffic signals. When an acceptable pothole size threshold has been exceeded, a crew would be dispatched to repair the damaged road.

Effective use of the repair crews and equipment could include the pre-emptive repair of less severe road damage also detected near or en route to the car-swallowing crater in question.
