EMTRAC Intelligent Transportation Systems (ITS)
Cities face a number of challenges when implementing ITS (Intelligent Transportation Systems) technology. Even the most forward-looking municipalities must navigate the imposing scale of employing ITS functionality. The EMTRAC system provides key ITS elements, which it can deliver through a number of protocols and means, including FHSS radio, cellular, NTCIP, DSRC (dedicated short-range communications), J1708/J1939, and SDLC.
Functionality provided by the EMTRAC system includes adaptive TSP (Transit Signal Priority), Emergency Vehicle Preemption (EVP), real-time AVL (automatic vehicle location), accurate vehicle detection (including bicycles and motorcycles), pedestrian-crossing access, transit rail-vehicle and rail-worker safety, and more.
Municipal Vehicle Signal Priority
The EMTRAC system utilizes reliable GPS technology and secure frequency-hopping spread spectrum radio to enable municipal vehicles to request priority through signalized intersections.
Vehicles with the EMTRAC system transmit a priority request to equipped intersections when passing through geographic detection zones. The intersection-control cabinet contains an EMTRAC Priority Detector, which relays the priority-request to the signal controller.
