Other Micromobility Vehicle OBEs --> Micromobility Vehicle OBE:
VRU path prediction

This triple is bi-directional. See also Micromobility Vehicle OBE --> Other Micromobility Vehicle OBEs: VRU path prediction

Definitions

VRU path prediction (Information Flow): The predicted future path of travel by the VRUs equipment. This flow includes an indication of the future positions of the transmitting traveler that can be used by receiving connected devices to support coordinated travel maneuvers and enhance collision avoidance.

Other Micromobility Vehicle OBEs (Source Physical Object): 'Other Micromobility Vehicle OBEs' represents other connected low-powered mobility devices that are communicating with a host micromobility vehicle OBE. This includes all connected PIDs, personnel devices, and micromobility vehicles that supports communications among vulnerable road users (P2P). This object provides a source and destination for information transfers between connected vulnerable road users. The host micromobility vehicle OBE sends information to, and receives information from the micromobility vehicle OBE to model communications between connected micromobility vehicles in ARC-IT.

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.

Communication Solutions

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - LTE-V2X WSMP

Solution Description

This solution is used within the U.S.. It combines standards associated with (None-Data) with those for V-X: LTE-V2X WSMP. The (None-Data) standards include an unspecified set of standards at the upper layers. The V-X: LTE-V2X WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications using the WAVE Short Messaging Protocol (WSMP) over 3GPP C-V2X in the 5.9GHz spectrum.

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Low High Moderate
Basis Information intentionally shared with surrounding users that might cooperate. Initial use cases suggest broadcast-mode communications, and no presumption of obfuscation. MMV clustering applications need timeliness and protection of data to ensure that platooning-like operations happen without incident. Data integrity protections rated higher than availability because incorrect/modified data could lead to catastrophic consequences given the lack of protection that most MMVs offer, and the fact that they operate in close proximity to pedestrians.
