Personal --> Traveler:
traveler interface updates
Definitions
traveler interface updates (Information Flow): Visual or audio information (e.g., routes, messages, guidance, emergency information) that is provided to the traveler.
Personal (Source 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.
Traveler (Destination Physical Object): The 'Traveler' represents any individual who uses transportation services. The interfaces to the traveler provide general pre-trip and en-route information supporting trip planning, personal guidance, and requests for assistance in an emergency that are relevant to all transportation system users. It also represents users of a public transportation system and addresses interfaces these users have within a transit vehicle or at transit facilities such as roadside stops and transit centers.

| Interoperability | Description |
|---|---|
| Not Applicable | Interoperability ratings don't apply per se to some types of interfaces like human interfaces. These interfaces may still benefit from associated standards (e.g., ergonomic and human factors standards for human interfaces), but the primary motive for these standards is not interoperability. |

| Basis | Personalized data that includes directions and guidance for an individual, but eventually evident anyway. | Should be accurate as the Traveler will be relying on this information for routing and related choices. Lack of accuracy will result in lack of confidence from the traveler as well as an unsatisfactory trip, leading to a negative feedback spiral. | Users expect their devices to work. If information is not presented to the operator, the relevant applications simply won't be used. | |
