Vulnerable Road Users --> ITS Roadway Equipment:
vulnerable road user presence

Definitions

vulnerable road user presence (Information Flow): Detection of pedestrians, cyclists, and other vulnerable road users. This detection is based on physical characteristics of the user and their conveyance, which may be enhanced by design and materials that facilitate sensor-based detection and tracking of vulnerable road users.

Vulnerable Road Users (Source Physical Object): 'Vulnerable Road Users' represents any roadway user not in a motorized vehicle capable of operating at the posted speed for the roadway in question, and also any roadway user in a vehicle not designed to encase (and thus protect) its occupants. This includes pedestrians, cyclists, wheelchair users, two-wheeled scooter micromobility users, as well as powered scooters and motorcycles. Note that this terminator represents the physical properties of vulnerable road users and their conveyance that may be sensed to support safe vehicle automation and traffic management in mixed mode applications where a variety of road users share the right-of-way. See also 'Pedestrian' and 'MMV User' Physical Objects that represent the human interface to these vulnerable road users.

ITS Roadway Equipment (Destination Physical Object): 'ITS Roadway Equipment' represents the ITS equipment that is distributed on and along the roadway that monitors and controls traffic and monitors and manages the roadway. This physical object includes traffic detectors, environmental sensors, traffic signals, highway advisory radios, dynamic message signs, CCTV cameras and video image processing systems, grade crossing warning systems, and ramp metering systems. Lane management systems and barrier systems that control access to transportation infrastructure such as roadways, bridges and tunnels are also included. This object also provides environmental monitoring including sensors that measure road conditions, surface weather, and vehicle emissions. Work zone systems including work zone surveillance, traffic control, driver warning, and work crew safety systems are also included.

Interoperability Description
Not Applicable Interoperability ratings don't apply per se to some types of interfaces like human interfaces. These interfaces may still benefit from associated standards (e.g., ergonomic and human factors standards for human interfaces), but the primary motive for these standards is not interoperability.
