We develop a new traffic data collecting device. The device is based on magneto-resistive technology, in which the circuit resistance is changed with the imposing magnetic field. It is known that ferrous-body vehicles interfere with Earth's magnetic field, which can be monitored with our device. The signal will then be processed and yields vehicle count, speed, occupancy time, and classification. We also design our device to communicate to its base station via radio frequency. We form a network… CONTINUE READING
