Other Connected Vehicle Roadside Equipment --> Connected Vehicle Roadside Equipment:
detected unequipped vehicles and VRUs

This triple is bi-directional. See also Connected Vehicle Roadside Equipment --> Other Connected Vehicle Roadside Equipment: detected unequipped vehicles and VRUs

Definitions

detected unequipped vehicles and VRUs (Information Flow): Notification of a nearby vehicle (light vehicle, commercial vehicle, MMV etc.) or vulnerable road user that does not appear to be equipped with a short range communications device but is detectable using onboard vehicle or infrastructure sensors. The flow communicates detected vehicle/VRU location, physical characteristics, observable kinematics and confidence in those measures.

Other Connected Vehicle Roadside Equipment (Source Physical Object): Representing another Connected Vehicle Roadside Equipment, 'Other Connected Vehicle Roadside Equipment' supports peer to peer communication and direct coordination between RSEs. It provides a source and destination for information that may be exchanged between RSEs.

Connected Vehicle Roadside Equipment (Destination Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices (i.e., Roadside Units (RSUs)) equipped with short range wireless (SRW) communications technology, as well as any other supporting equipment that leverage the RSU and are not described by other objects (e.g., a local roadside processor). CVRSE are used to send messages to, and receive messages from, nearby vehicles and personal devices equipped with compatible communications technology. 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.

Basis This data is intended to be shared with all nearby vehicles, traffic control devices and vulnerable road users; it is essentially public. This data may be used as input to vehicle situational awareness and thus trigger crash-avoidance actions. If manipulated or incorrect, a crash may occur; though vehicles able to use this data also have sensory capabilities, this flow will often contain data describing objects/vehicles/VRUs that are obscured and not observable by on-board sensors. This data may be used as input to vehicle situational awareness and thus trigger crash-avoidance actions. This data enable collision avoidance actions that are impractical without it, as vehicles able to use this data to sense-by-proxy other vehicles/VRUs/obstacles that are obscured by on-board sensors. Considered MODERATE and not HIGH only because the lack of availability reverts to existing operations and does not actively make safety worse.
