ITS Roadway Equipment --> Connected Vehicle Roadside Equipment: vehicle signage local data Definitions
vehicle signage local data (Information Flow): Information provided by adjacent field equipment to support in-vehicle signing of dynamic information that is currently being displayed to passing drivers. This includes the dynamic information (e.g., local traffic and road conditions, work zone information, lane restrictions, detours, closures, advisories, parking availability, etc.) and control parameters that identify the desired timing, duration, and priority of the signage data.
ITS Roadway Equipment (Source 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.
Multi-Access Edge Computing (Destination 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
