The majority of current TxDOT traffic signal equipment is compatible with FYA operation. TxDOT signal cabinets, as currently equipped, can be modified to perform FYA. Prior to installing or converting an intersection to FYA left-turn operations, it will be necessary to ensure that there is adequate field wiring, the signal controller cabinet has adequate channels (load switches), and the controller and Malfunction Management Unit (MMU) are capable of FYA operation. Configuration of the traffic signal cabinet may be dependent on several conditions at the intersection such as the controller requirements, the monitor requirements, the cabinet size and available load switches, and whether pedestrian signals are being utilized. Careful planning is required to ensure a successful installation.
