maintenance_vehicle_roadway_priorities

This data flow is sent from the Manage Maintenance and Construction function to the Manage Traffic function and contains data necessary for an individual maintenance and construction vehicle to be given priority at traffic signal controllers. This will be at the controller for a particular road intersection, pedestrian crossing, or highway entrance ramp. The data is sent directly from the maintenance vehicle to the next controller along its route and therefore is not subject to any centralized coordination. Local coordination may be provided if there are links between adjacent controllers. The data flow consists of the following data items each of which is defined in its own DDE:

maintenance_vehicle_intersection_priority
+ maintenance_vehicle_pedestrian_priority
+ maintenance_vehicle_ramp_priority
