OSPOCX from Tomar
500-085
The AI-500-085 Glance Preempt & Priority FMU series of controllers from Applied Information,provides a cost-effective, easy to integrate means of adding priority & preemption as well as monitoring traffic intersections status and health. The unit has a build in Cellular, GPS and 900MHz radio to make priority and preemption easy to configure and simple to set up. The 19-inch rack mounted device is capable of remotely switching NEMA 5-15 power outlets inside the ITS cabinets. It is designed for extreme temperature applications and has low power requirements, making it suitable for solar powered applications.

OSPOCx Coded
The Optical Signal Processor (OSP) receives the electrical signals from the optical preemption Detectors. While being received, the signals are processed to determine if the vehicle is a valid emergency or transit vehicle.
The OSP is connected directly to the preemption inputs of the traffic controller in the intersection in which it is installed. When a vehicle’s signal is accepted as valid, the OSP sends a preemption request to the proper input of the traffic controller.
The traffic controller then safely manipulates the traffic signals according to a preprogrammed algorithm. Depending on where the traffic controller was in its normal routine the vehicle will receive a “Green Light” after a minimum of 3 or more seconds. Traffic signals which are already green will stay green until the vehicle passes.
If multiple vehicles are being received, they are prioritized to determine which vehicle should be given the right of way. If vehicles are of equal priority, right of way is given on a first-come, first-served basis.
4080 OSP from Traffic Products
4080 Optical Signal Processor
Installed inside the traffic cabinet at an intersection, the 4080 Optical Signal Processor (OSP) provides power for 209X and 4090 Optical Detectors, receives, decodes and prioritizes signals from the detectors, communicates with other traffic control devices, and optically isolates the preemption channels.
The 4080 responds on a first-come, first-served basis to optical signals from vehicles within two signal bands. Emergency band signals are typically emitted by emergency vehicles to effect a preemption of normal traffic control timing and are given the highest priority to allow rapid emergency response with enhanced safety. Transit band signals are generally emitted by transit or other non-emergency municipal vehicles to effect a priority change for the vehicle’s approach direction without necessarily interrupting traffic control timing.
