Optical Signal Processor Cards
with 1881 Card Cage and Wire Harness
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.
