Sensys Offers New Traffic-Control Technology

June 8, 2007

The Wireless Vehicle Detection System enables applications such as permanent count stations, advance detection, stop-bar detection, and ramp management.


BERKELEY, CA /BUSINESS WIRE/ -- Sensys Networks Inc. announced that the Sensys Wireless Vehicle Detection System is now capable of supporting stop-bar detection for traffic signal control applications. As a result, Sensys wireless sensors can be used as a direct replacement for conventional inductive loops at intersections, but without pavement cuts or lead-in cabling. Thanks to its fast and simple installation and its resilience to traffic damage, the Sensys Wireless Vehicle Detection System provides a cost-effective option for vehicle detection at intersections, whether it is a new installation or the retrofit of an existing one.

The Sensys Wireless Vehicle Detection System has earned a reputation in the traffic-management industry as a reliable and accurate solution for permanent count station and advance detection applications. The latest software release for the Sensys Wireless Vehicle Detection System extends the system's capabilities to encompass stop-bar-detection modes for traffic-signal control applications. With sixteen new sensitivity modes, the Sensys Wireless Vehicle Detection System can be tuned to accurately detect the presence of automobiles, motorcycles, scooters, and bicycles at intersections. To ensure that detection signals are delivered to the traffic signal controller as reliably and as quickly as possible, the latest Sensys software release also includes improvements to both vehicle-detection algorithms and radio performance.

The Sensys Wireless Vehicle Detection System can be used with Type 170, NEMA TS1, NEMA TS2, or Type 2070 ATC traffic controllers, converting the real-time detection signals of the Sensys wireless sensors into contact closure signals to the traffic controller. Using pulse or presence modes and mapped as required to different detector groups and signal phases, the Sensys Wireless Vehicle Detection System can be easily configured in the same way that inductive loops would interface to a traffic controller. Unlike loops, however, each Sensys wireless sensor can be installed in less than 10 min., making installation of the Sensys Wireless Vehicle Detection System a much faster and less expensive option.

"With this new capability, Sensys now offers a single, flexible vehicle-detection platform for permanent count stations, advance detection, stop-bar detection, and ramp management," said Amine Haoui, CEO of Sensys Networks. "The Sensys Wireless Vehicle Detection System represents the most important new technology for intersection traffic control since the emergence of video over a decade ago."

About the Sensys Wireless Vehicle Detection System
The Sensys Wireless Vehicle Detection System uses rugged pavement-mounted magneto-resistive sensors to detect the presence and movement of vehicles. The Sensys vehicle sensors are wireless, transmitting their real-time detection data via radio to a nearby Sensys access point, which communicates the data to a local traffic controller, a remote traffic-management system, or to both at once. Thanks to patent-pending innovations by Sensys Networks in low-power circuitry and communications protocols, the battery life of a sensor is expected to be 10 years.

About Sensys Networks
Based in Berkeley, CA, Sensys Networks has combined state-of-the-art magnetic sensors with innovative low-power radio technology to create a reliable, accurate, and cost-effective vehicle-detection system with the flexibility to address a wide range of traffic-management applications. The Sensys Wireless Vehicle Detection System uses sophisticated detection and wireless communications technologies to create a new vehicle-sensing system that promises to be an essential component of traffic-management systems for the 21st century.
