  Preemption and Priority Equipment - Optical EVP Detectors
  Our Optical Preemption Detectors sense the optical pulses emitted by properly equipped emergency or transit vehicles. Mounted to observe the approaches of an intersection, these are used with Optical Signal Processors to inform the traffic control system of the presence of designated vehicles. Using our detectors throughout your traffic control system reduces emergency response time, allows emergency vehicles to travel with greater safety, and improves transit vehicles timeliness.
