pedestrian crossing monitoring and field equipment coord Quintuple

Bidirectional?: True

pedestrian crossing monitoring and field equipment coord (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'Roadway Pedestrian Crossing Safety', and 'RSE 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.

Roadside Equipment (Destination Physical Object): 'Roadside Equipment' (RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.

RSE Intersection Safety (Destination Application Object): "RSE Intersection Safety" uses short range communications to support connected vehicle applications that improve intersection safety. It communicates with approaching vehicles and ITS infrastructure to alert and warn drivers of potential stop sign, red light, and pedestrian crossing conflicts or violations.
