GTT’s Opticom to get location tracking Chipset

Global Traffic Technologies adds Global Navigation Satellites System to its platform to ensure customers get accurate, reliable priority control - even in dense urban areas

Global Traffic Technologies (GTT) announced that it has added the Global Navigation Satellites System (GNSS) to its Opticom™ solutions. This collection of satellites transmits positioning and timing data to GNSS receivers, which use this data to determine location.

Adding GNSS will enable more consistent, reliable priority control in dense urban areas with obstructions such as bridges, tunnels, and tall buildings. It will reduce the type of performance issues that can reduce priority control’s effectiveness by helping make sure the correct intersection receives the request for a green light as priority vehicles approach intersections. Better location services will minimize interference to traffic, and help fire and emergency personnel, bus drivers and light rail train conductors navigate dense urban areas in safer and faster.

Even with access to more satellites, communication to these satellites is often lost temporarily in areas with tall buildings, tunnels, or multi-level roads. To address this issue, GTT has also added the power to more effectively determine vehicle position in these areas with software-based “dead reckoning.” If satellite communication is lost, dead reckoning can calculate a moving vehicle’s position by estimating its direction and distance traveled from its last known geo-location. GTT’s software-based dead reckoning solution functions with sensors built into the Opticom devices, with no additional vehicle wiring required.
