Non-Intrusive Sensors

Acoustic Sensor

SAS-1 is an easy to use, programmable acoustic sensor ready to detect multiple lanes of traffic for real-time operations, or to collect traffic counts with 3 levels of classification.

Microwave Sensor

The Remote Traffic Microwave Sensor is a low-cost advanced sensor for the detection and measurement of traffic at intersections and on roadways. The RTMS is a small radar operating in the microwave band. Mounted on road-side poles, it is easy and safe to install and remove without traffic disruptions or lane closures.

TMS-SA Traffic Counter/Classifier

The TMS-SA is a compact, portable and non-intrusive traffic counter/classifier that is ideal for temporary surveys in urban and residential areas. The TMS-SA counts vehicles, measures speed, and classifies up to four length categories. Ease of use, all-weather operation, and an included data-analysis software package make the TMS-SA a great alternative to counter/classifiers that use on-road sensors.
