pedestrian interaction Quintuple

Bidirectional?: True

pedestrian interaction (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'Roadway Pedestrian Crossing Safety' application object and the 'Pedestrians' physical object. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

Pedestrians (Source Physical Object): 'Pedestrians' participate in connected vehicle applications that support safe, shared use of the transportation network by motorized and non-motorized transportation modes. Representing those using non-motorized travel modes, pedestrians provide input (e.g. a call signal requesting right of way at an intersection) and may be detected by connected vehicle applications to improve safety. Note that pedestrians represent all non-motorized users, including bicyclists.

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 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 (Destination 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.
