Abstract: Aspects identify different, mutually exclusive actions that each apply to usage of a roadway during occurrences of different respective associated combinations of temporal and road condition values. Current temporal data and combination road condition values that are associated with the mutually exclusive actions are determined. An active electronic display of a traffic sign device is driven to indicate one of the mutually exclusive actions as an active traffic requirement as a function of an association of the combination of the determined temporal and road condition values with the action, and to indicate a time or road condition value that differs from a respective one of the combination of the determined temporal and road condition values that are associated with the action as relevant to triggering application instead of another, different one of the mutually exclusive actions as the active traffic requirement.
