Traveler --> Personal Information Device:
traveler input
Definitions
traveler input (Information Flow): User input from a traveler to summon assistance, request travel information, make a reservation, or request any other traveler service.
Traveler (Source 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.
Personal Information Device (Destination Physical Object): The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help.

| 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 | This data is informing the vehicle of operational information that is relevant to the operation of the vehicle. It should not contain anything sensitive, and does not matter if another person can observe it. | While public, information must be correct or travelers may make incorrect decisions with regard to their travel plans. | Information is available through other means, though depending on the location this might not always be the case, in which case this would be MODERATE. | |
