By utilizing sophisticated detection and wireless communications technologies to develop a new pavement-mounted vehicle sensing system, Sensys has created an essential component of traffic management systems for the 21st century – the Sensys™ Wireless Vehicle Detection System.
The Sensys Wireless Vehicle Detection System uses pavement-mounted magnetic sensors to detect the presence and movement of vehicles. The magneto-resistive sensors are wireless, transmitting their detection data in real-time via low-power radio technology to a nearby Sensys access point that then relays the data to one or more local or remote traffic management controllers and systems.
A single Sensys installation thus consists of a number of Sensys wireless sensors installed in or on the roadway at various locations as required by the particular vehicle detection application, a Sensys access point to receive the data from the sensors and process and relay it onward, and one or more Sensys repeaters as may be needed to support sensors installed beyond the radio range of the Sensys access point. Each Sensys installation can then communicate its detection data in several ways:
- via contact closure to a roadside traffic controller;
- via IP (Internet Protocol) communications over twisted pair, coaxial cable, fiber optic cable, cellular data services, or other connectivity to one or more central servers and traffic management systems, where the Sensys Networks Archive, Proxy, and Statistics (SNAPS) server is an example of such a central server; or
- via both paths, simultaneously supporting local traffic signal control as well as centralized traffic management and information systems.
