Personal Information Device --> Other PIDs:
VRU hazard event

Definitions

VRU hazard event (Information Flow): Notification of a potential hazard or event that is detected or reported by the traveler or vulnerable road user (VRU) using a PID or riding a micromobility vehicle (MMV). Potential hazards may be determined by sudden movements by travelers, such as movements around a location which may indicate foreign objects (people, animals, debris, other obstacles) in the travel lanes. Hazards may also be manually entered by the traveler into a personal information device (e.g., crowdsourcing) to be shared with other travelers.

Personal Information Device (Source 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.

Other PIDs (Destination 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.
