signal_priority_override

This data flow is sent to the Select Strategy function to indicate that a roadside controller has changed its original timing plan in response to a request for priority from the Manage Transit function. This will be at the controller for a particular intersection, pedestrian crossing, or highway entrance ramp. The data is sent directly from the signal as an override function rather than a signal malfunction.
