Decrease Travel Time — Increase Safety

The EMTRAC Priority Management System uses precise navigation technology and secure RF communication to detect equipped transit, emergency, and municipal vehicles and to place priority or preemption requests to intersection signal-control equipment.

Effective and safe fire traffic preemption (that is, Emgergency Vehicle Preemption or EVP) is best accomplished by a system that knows how to serve multiple equipped vehicles approaching the same intersection. The system should also include multiple priority levels for individual vehicles. The EMTRAC system includes these capabilities and many others.

Traffic signal priority may include more advanced features, such as adaptive priority. EMTRAC adaptive signal priority enables vehicles to communicate current enroute conditions so traffic controllers can adjust phase timing before granting traffic signal priority. Other capabilties, such as Conditional Signal Priority and Actuated Priority are also available with the EMTRAC system. Refer to our Transit Signal Priority (TSP) page for more information.
