Uses wireless magneto-resistive sensors to detect the presence and movement of vehicles. The sensors are installed on the surface or in small holes cored in the roadway and transmit detection data in real-time via low-power radio technology to a nearby access point. Vehicle detections are further relayed to a traffic signal controller, remote traffic management center, or other system.
In typical traffic management applications, a sensor is placed in the middle of a traffic lane to detect the presence and passage of vehicles. Vehicle speeds and length are measured by two sensors installed in the same lane with the exact distance between them configured in software.
The recommended distance between sensors depends on the range of expected speeds to be measured: for typical freeway applications, a separation of 20'–24' (6.1 to 7.3 meters) is recommended; for typical arterial applications, a separation of 10'–12' (3.1 to 3.7 meters) is preferred.
