Abstract: A vehicle detecting system and method for use on a specific location such as an airport, including a sensor string nominally perpendicular to the direction of vehicle travel at the location. The sensor string includes at least one magnetic field sensor and a transmitter for transmitting signals from the at least one sensor to a monitoring point. A plurality of sensors is preferred. The transmitter includes a control unit for receiving the signals and a sender for sending the signals to the monitoring point. The preferred magnetic field sensor is a magnetoresisteive sensor having a field range of at least ±5 gauss. A preferred location for the sensor string is in a groove in the surface.
