Other PIDs --> Personal Information Device:
personal location
This triple is bi-directional. See also
Personal Information Device --> Other PIDs: personal location
Definitions
personal location (Information Flow): The current location (latitude, longitude, and elevation) reported by the personal information or safety device
Other PIDs (Source Physical Object): 'Other PIDs' represents other personal information devices (PIDs) that are communicating with the device. This includes all connected personal information devices that support wireless short-range communications, including those used by pedestrians, cyclists, and other vulnerable road users (VRUs). This object provides a source and destination for information transfers between connected personal devices. The host device, represented by the Personal Information Device physical object, sends information to, and receives information from the Other PIDs to model all connected personal-to-personal (P2P) communications in ARC-IT.
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.

Basis | This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. | An incorrect location message could lead to a false warning or lack of warning. A lack of warning can have obvious catastrophic consequences, while a false warning could lead to users ignoring warnings due to perceived inaccuracy. Given that this triple may apply to highly dynamic environments (such as work zones), its accuracy is paramount, and thus if sent, must have HIGH integrity. | There are other visual indicators about the geofenced areas. PID users in dynamic environments (incident and work zones) should know when they are leaving a geofenced area. As long as they remain in the geofenced area, this information is not as necessary. Not all pedestrians will carry a personal information device, and the system should be able to operate without this information. |
