Other PIDs --> Personal Information Device:
VRU cluster information
This triple is bi-directional. See also
Personal Information Device --> Other PIDs: VRU cluster information
Definitions
VRU cluster information (Information Flow): Information indicating the formation and management of strings of VRUs and micromobility vehicles, which includes human powered vehicles such as bicycles, that may follow each other towards a common destination. This flow also supports identification of the lead MMV in the string so other MMVs can opt-in to join the string. The indication of participating in a string provides better predicted path trajectory prediction for all participating MMVs, enhancing safety. This flow also supports dissolution of MMV strings as MMVs depart from the string.
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 | Information intentionally shared with surrounding users that might cooperate. Initial use cases suggest broadcast-mode communications, and no presumption of obfuscation. | MMV clustering applications need timeliness and protection of data to ensure that platooning-like operations happen without incident. Data integrity protections rated higher than availability because incorrect/modified data could lead to catastrophic consequences given the lack of protection that most MMVs offer, and the fact that they operate in close proximity to pedestrians. | MMV clustering applications need timeliness and protection of data to ensure that platooning-like operations happen without incident.
