Pre-emption systems combine onboard systems and traffic light vehicle sensors to give priority access to transit and emergency service vehicles. In time-sensitive situations, the system will detect that the vehicle is approaching an intersection and give them a green light while halting other traffic.

GTT designs the Opticon emergency and transit vehicle pre-emption systems. These help police cars, fire trucks, ambulances, and buses get through busy intersections more quickly while reducing the risk of accidents. They also manufacture the Canoga Traffic Sensing system, which detects a vehicle’s speed, class, and count to help you plan construction and improve traffic flow.
