Connected Vehicle Roadside Equipment --> Micromobility Vehicle OBE: 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.
Multi-Access Edge Computing (Source Physical Object): 'Multi-Access Edge Computing' ((MEC) previously known as mobile edge computing) represents computing devices that operate and are managed like a cloud server, but are deployed at the edge of a network (typically a cellular network, but it could be any network). While not in strict proximity to the transportation network, these systems do benefit from vastly decreased distances to the roadway compared to central systems, and so can provide lower latency than strictly backoffice systems
Micromobility Vehicle OBE (Destination Physical Object): The Micromobility Vehicle On-Board Equipment (MMV OBE) provides the vehicle-based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. The MMV OBE includes general capabilities that apply to bicycles and other low-powered mobility devices such as e-scooters, powered wheelchairs, and power assisted bicycles. The MMV OBE includes the common interfaces and functions that could apply to any low-powered mobility device. The radio(s) supporting V2V and V2I communications are a key component of the MMV OBE. 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, and enhanced traveler interfaces (through PIDs), complement traveler information services so that, in addition to making informed mode and route selections, the vulnerable road user travels these routes in a safer and more consistent manner.

| 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. | |
