Pathway Equipment --> Micromobility Vehicle OBE:
pathway signage information

Definitions

pathway signage information (Information Flow): Pathway information that is electronically provided to the PID Includes pathway status, as well as alerts or warnings.

Pathway Equipment (Source Physical Object): 'Pathway Equipment' represents the equipment that is distributed along pathways that monitors and supports movement on the pathways and interfaces with electronic devices used by travelers on the pathways. This physical object includes elevators, escalators, electronic turnstiles, pedestrian (and other VRU) detectors, electronic signage, electronic waypoints, and warning systems for pathway users.

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

US: SAE Traveler Info - Local Unicast Wireless (1609.2)

Solution Description

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Traveler Info with those for V-X: Local Unicast Wireless (1609.2). The US: SAE Traveler Info standards include upper-layer standards required to implement V2X traveler information flows. The V-X: Local Unicast Wireless (1609.2) standards include lower-layer standards that support local-area unicast wireless solutions applicable to North America, such as WAVE DSRC, LTE-V2X, LTE, Wi-Fi, etc.

Rating Low Moderate Moderate
Basis Probably no obfuscation is needed as most of the information in this flow should be otherwise observable. Information should be correct and available or wayfinding will not function well. A re-levelling of integrity measures may consider this LOW, depending on the importance of wayfinding. Information should be correct and available or wayfinding will not function well.
