Connected Vehicle Roadside Equipment --> Personal Information Device:
local METR information for users
Definitions
local METR information for users (Information Flow): This flow supports the provision of METR information to METR Consumer Systems based on their proximity to a localized transmitter.
Connected Vehicle Roadside Equipment (Source Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.
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 | This information is intended to be widely distributed and effectively public. | This information may be used to guide driver and AV behavior; incorrect or manipulated information could result in a vehicle performing a traffic movement that is not permitted, which in some cases (e.g., right turn on red) could be quite dangerous. | While it would be ideal if this information is always available, every user should have a safe fallback approach so the impact of a flow outage could degrade vehicle performance but should not result in significant material loss or safety impact. |
