Arterial Travel Time System

Stop Modeling What You Can Measure

Arterial optimization is elusive. Data gathered along these important transportation corridors is often from
unreliable, ad-hoc, sources—leaving planning to conjecture.

Free probe data has low penetration rates, is often inaccurate, and creates concerns over subscriber privacy. All these factors prevent traffic engineers from optimizing roadways—in real-time—especially at peak times.

Until now.

Sensys Wireless Arterial Travel Time (ATT) is the first turn-key, infrastructure-based solution addressing today's demand for accurate data to manage roadways. Sensys ATT has proven mission-critical in supplying the data driving traveler information systems, ramp metering, and signal timing optimization, as well as speed, volume, and occupancy statistics.

Cities and governments around the world are adopting our technology at an unprecedented rate. Citing quantifiable improvements in traffic flow and significant reductions in vehicle generated green house gases, Sensys Networks ATT is solving complicated 21st century transportation problems.
