An embedded Tire Pressure Monitoring sensor is incorporated into vehicular wheels and a secured central server is used to track the unique identification code of each sensor. The TPMS is installed by the vehicular manufacturer in accordance with the federally mandated TREAD Act of 2000. When a vehicle enters the radius of a first encrypted TPM sensor detection transceiver, its TPM sensor identification codes are recorded and time-stamped via an encrypted TPM sensor detection transceiver. If the vehicle enters the area of a second encrypted TPM sensor detection transceiver, the sensor codes will be recorded and time-stamped a second time, encrypted and sent to the secured central server. Using the two encrypted, time-stamped signals, the secured central server calculates traffic flow data.
