personal location (Information Flow): The current location (latitude, longitude, and elevation) reported by the personal information or safety device

Micromobility Vehicle OBE (Source 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.

Other Micromobility Vehicle OBEs (Destination 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.

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

US: SAE VRU Messages - WAVE WSMP

Solution Description

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE VRU Messages with those for V-X: WAVE WSMP. The US: SAE VRU Messages standards include upper-layer standards required to implement vulnerable road user information flows. The V-X: WAVE WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications within ~300m using the WAVE Short Messaging Protocol (WSMP) over IEEE WAVE in the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.

Basis	This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators.	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.	There are other visual indicators about the geofenced areas. PID users in dynamic environments (incident and work zones) should know when they are leaving a geofenced area. As long as they remain in the geofenced area, this information is not as necessary. Not all pedestrians will carry a personal information device, and the system should be able to operate without this information.
