SAS-1 Acoustic Traffic Counter

The SAS-1 operates in the adverse environments found on roadside structures. SAS-1 is an easy to use, programmable sensor ready to detect multiple lanes of traffic for real-time operations, or to collect traffic counts with 3 levels of classification.

Advanced signal and spatial processing provides the capability for high resolution multi-lane traffic flow monitoring with no loss of "lane switchers" at the detection zone. The SAS-1 is quickly and easily installed, with no lane closures needed for the "side-fire" configuration. Low power consumption supports operating entirely from solar power.
