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.

Communication Solutions

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

US: SAE VRU Messages - WAVE WSMP

Solution Description

This solution is used within the U.S.. It combines standards associated with US: SAE VRU Messages with those for V-X: WAVE WSMP. The US: SAE VRU Messages standards include upper-layer standards required to implement vulnerable road user information flows. The V-X: WAVE WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications within ~300m using the WAVE Short Messaging Protocol (WSMP) over IEEE WAVE in the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.

Interoperability Description
National This triple should be implemented consistently within the geopolitical region through which movement is essentially free (e.g., the United States, the European Union).

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.
