Signs and markings for people in motion — road signs, railway and maritime signals, aviation markings, and the national sign families that organise them.
Here when the mark governs or informs movement through a network. A vehicle's own instrument symbols are filed under vehicle dashboard, because a driver reads those for the state of the machine rather than the state of the road.
Almost entirely officially standardised, and unusually jurisdictional: the same instruction is drawn differently in different countries, and the records say which convention each one follows.
