signal_override_status

This data flow is sent to the Manage Traffic function and contains data pertaining to the request from the Manage Transit function or Manage Emergency services for signal priority or signal preemption. This will be at the controller for a particular road junction, pedestrian crossing, or highway entrance ramp. The data is sent directly from the signal as an override function rather than a signal malfunction. The data flow consists of the following data items each of which is defined in its own DDE:

emergency_vehicle_preemptions
+ transit_vehicle_roadway_priorities
