Low cost portable roadside sensor system estimates vehicle velocity within 2 percent accuracy and provides 100 percent accuracy of vehicle classification.
The sensor consists of magnetoresistive devices that measure magnetic field. The speed of the passing vehicle is estimated by calculating the cross-correlation between longitudinally spaced sensors.…
