Personal Information Device --> Other PIDs: emergency acknowledge
Definitions
emergency acknowledge (Information Flow): Acknowledge request for emergency assistance and provide additional details regarding actions and verification requirements.
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 | As the request for emergency assistance is by definition going to be a broadcast, the response can be reasonably assumed as not containing any personal information. | An incorrect message may mislead the originator of the emergency request, which could affect his behavior | If this flow is not delivered the worst case is probably that the originator of the emergency request keeps asking for emergency assistance. There may be some channel loading issues, but unlikely to require anything beyond LOW. |
