Specialization GeneralInstructionOrMessageToRoadUsers (Instructions to Road Users)
The type GeneralInstructionOrMessageToRoadUsers is derived from NetworkManagement, with the SituationRecord specialization OperatorAction above it. GeneralInstructionOrMessageToRoadUsers is used to influence the behavior of road users. This includes instructions such as keeping to the right and not overtaking. In addition to the basic elements of a SituationRecord, specific elements of OperatorAction and NetworkManagement, the specialization includes two additional elements: the mandatory element generalInstructionOrMessageToRoadUsersType and generalMessageToRoadUsers.
The structure is as follows (elements from NetworkManagement are shown in a shortened form):
In this specialization, providing a classification of the instruction is mandatory. The different possibilities for this classification can be found in the possible domain values of the element generalInstructionOrMessageToRoadUsersType. This information may be supplemented with an additional message in the optional element generalMessageToRoadUsers.
