1. A system for characterizing a roadway, the system disposed in a vehicle for enabling mobile roadway characterization over a range of driving speeds, comprising:

  • a dynamic tire pressure sensor coupled to a valve stem of a first tire of the vehicle for dynamically measuring tire pressure changes caused by the interaction of the respective tire and the roadway while the vehicle is moving on the roadway;

    signal processing circuitry, centrally disposed on a first wheel of the vehicle, the first tire being mounted on the first wheel and the signal processing circuitry being in electrical communication with the pressure sensor for receiving dynamic tire pressure data therefrom; and

    a signal recovery and processing computer having an associated database, the computer disposed with the vehicle for receiving the processed tire pressure data from the signal processing circuitry, for analyzing the received data to characterize the roadway on which the vehicle is traveling, and for storing the analyzed data in the database.
