Microwave detection systems include two primary elements: 1) An antenna that transmits electro-magnetic energy towards an intersection approach or roadway section, and 2) A Receiver that scans for energy that is transmitted back to the unit as a vehicle or object passes through the energy waves. Advanced microwave systems include multiple antennas and receivers that transmit on different frequencies to improve detection accuracy.


Microwave technology can be used for both vehicle limit line intersection detection or for traffic data collection applications. Manufacturer specific software algorithms can further refine systems to include bicycle differentiation and detection and a growing trend is to fuse traditional video and microwave solutions to offer improved intersection detection.

The MS SEDCO Intersector line is an industry leader in the use of bicycle differentiation using microwave. While the Intersector offers both vehicle and bicycle differentiation, it is not uncommon to see some agencies using the Intersector for bicycle detection only while they rely on video detection or traditional inductive loops.


The MS SEDCO Smart Walk system is the industry standard for microwave detection of pedestrians. The Smart Walk system can be used to feed data into the traffic signal controller to extend green displays if pedestrians are detected to be in crosswalks and to active lighting systems along trails.
