pedestrian safety application monitoring and control info Quintuple

Bidirectional?: True

pedestrian safety application monitoring and control info (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'Roadway Pedestrian Crossing Safety', and 'TMC Intersection Safety'. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

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 itself. In CVRIA, this physical object represents all of the other ITS field equipment that interfaces with and supports the Connected Vehicle Roadside Equipment (RSE). 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.

Roadway Pedestrian Crossing Safety (Source Application Object): "Roadway Pedestrian Crossing Safety" is an advanced infrastructure application that detects pedestrians and provides active safety warnings to drivers when cross walks are occupied.

Traffic Management Center (Destination Physical Object): The 'Traffic Management Center' monitors and controls traffic and the road network. It represents centers that manage a broad range of transportation facilities including freeway systems, rural and suburban highway systems, and urban and suburban traffic control systems. It communicates with ITS Roadway Equipment and Connected Vehicle Roadside Equipment (RSE) to monitor and manage traffic flow and monitor the condition of the roadway, surrounding environmental conditions, and field equipment status. It manages traffic and transportation resources to support allied agencies in responding to, and recovering from, incidents ranging from minor traffic incidents through major disasters.

TMC Intersection Safety (Destination Application Object): "TMC Intersection Safety" controls and monitors RSEs that support stop sign, red light, and pedestrian crossing violations. It configures the RSEs for the current intersection geometry and traffic signal control equipment at the intersection. Information that is currently being communicated to passing vehicles and the operational status of the field equipment is monitored by this application. The operational status of the field equipment is reported to operations personnel.
