Location and Time Data Source --> Personal:
location and time

Definitions

location and time (Information Flow): The current geographic location in three dimensions (latitude, longitude, elevation) and the current time.

Location and Time Data Source (Source Physical Object): The 'Location and Time Data Source' provides accurate position information. While a Global Positioning System (GPS) Receiver is the most common implementation, this physical object represents any technology that provides a position fix in three dimensions and time with sufficient accuracy.

Personal (Destination Physical Object): The 'Personal' physical object is used to model core capabilities that are common to more than one physical object in the 'Personal' class. It provides the general executive, management, and utility functions that may be shared by different types of personal devices.

    InteroperabilityDescription
    RegionalInteroperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

    Security

    Information Flow Security

    Rating Moderate High High
    Basis While time reference should be universally available, time reference coupled with vehicle location is tracking data. This flow is internal to a vehicle, but should probably be encrypted to discourage hacking and snooping on the vehicle bus. Thus MODERATE. Location and time data is the basis for crash imminent safety and a host of other applications. Corruption of this flow could lead directly to a vehicle accident. If this information is not available, crash imminent safety applications depending on this information will not function properly.
