TRAFFIC PRIORITY MANAGEMENT SYSTEM

2. EMTRAC SYSTEMS
The Emtrac Priority Management System enables emergency and mass-transit
vehicles to request green signals for quick and safe passage through signalized inter-
sections. In many ways, the Emtrac System performs like a “Virtual Loop Detection
System” where each equipped class of vehicle is recognized differently by the system.
Emtrac customizes each individual vehicle to each approach to the intersection.
The Emtrac Priority Traffic Management System utilizes real-time vehicle position
data, a database of user-programmable intersection approach detection zones,
and a secure wireless telemetry to enable precise control of priority detection. By
using an advanced GPS receiver, the Emtrac Vehicle equipment determines the
vehicles position, direction, and velocity to a high degree of accuracy. The
rectangular intersection detection zones are user-definable for each vehicle and may
be combined or overlapped to handle curved roadways. Each detection zone has a
particular intersection controller’s priority request associated with it. As an Emtrac
equipped vehicle approaches the intersection, the vehicle computer compares the
position and direction of the approaching vehicle with pre-defined detection zone
data (stored in its memory) to determine if a priority control request should be
transmitted.
