Personal Information Device --> Vehicle:
personal location
Definitions
personal location (Information Flow): The current location (latitude, longitude, and elevation) reported by the personal information or safety device
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.
Vehicle (Destination Physical Object): This 'Vehicle' physical object is used to model core capabilities that are common to more than one type of Vehicle. It provides the vehicle-based general sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. Many of these capabilities (e.g., see the Vehicle Safety service packages) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle includes the common interfaces and functions that apply to all motorized vehicles. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Advanced sensors, processors, enhanced driver interfaces, and actuators complement the driver information services so that, in addition to making informed mode and route selections, the driver travels these routes in a safer and more consistent manner. This physical object supports all six levels of driving automation as defined in SAE J3016. Initial collision avoidance functions provide 'vigilant co-pilot' driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain lane position and safe headways. In the most advanced implementations, this Physical Object supports full automation of all aspects of the driving task, aided by communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems.

Basis | This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. THEA believes this to be 'LOW.' | 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. | This information should not be required to determine if a pedestrian is in an intersection. Not all pedestrians will carry a personal information device, and the system should be able to operate without this information. DISC: CCHANGED to Moderate from Low based on THEA justification: "location needs to be immediately available to enable warnings and messages from the PID to OBE but availability cannot be guaranteed over a wireless medium." |
