The AccuSense Mag – installed in holes cored in the roadway and covered with epoxy – transmit detection data in real-time via low-power radio technology to a nearby AccuSenseControl. Vehicle detections are further relayed to a traffic signal controller, remote traffic management center, or other system.

The new AccuSense Mag sensor utilizes the next generation of RF chipsets and circuitry. The AccuSense Mag sensors are installed flush with the roadway surface in plastic shells. The plastic shells enable the removal and replacement of sensors during roadway milling operations. The AccuSense Mag sensors are installed at depth of up to 4.25 inches (10.8 cm) below the top of the roadway surface without plastic shells. Sensors installed at these depths do not have to be removed and replaced during most roadway milling operations.  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 to 24 feet (6.1 to 7.3 meters) is recommended; for typical arterial applications, a separation of 10 to 12 feet (3.1 to 3.7 meters) is preferred.
