transit_vehicle_sign_priority
This data flow is sent from the Manage Transit function to the Manage Traffic function and contains data necessary for a transit vehicle to have a message output giving it priority at an indicator that is a particular dynamic message sign (DMS) or fixed message sign that has a transit priority message that can be displayed.
