rail crossing application monitoring and control info Quintuple

Bidirectional?: True

rail crossing application monitoring and control info (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'TMC Rail Crossing Management', and 'RSE Rail Crossing Warning'. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

Traffic Management Center (Source 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 Rail Crossing Management (Source Application Object): "TMC Rail Crossing Management" monitors and controls rail crossing traffic control equipment. Various levels of roadside equipment may be interfaced including standard active warning systems and high speed systems that provide additional information on approaching trains and detect and report obstructions on the grade crossing. This application remotely monitors and reports the status of the rail crossing equipment and sends control plan updates to the equipment.

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 Rail Crossing Warning (Destination Application Object): "RSE Rail Crossing Warning" is a connected vehicle application that improves safety at rail crossings. It communicates with wayside equipment that detects or communicates with approaching trains. It provides rail crossing warnings and train arrival information to approaching vehicles and monitors connected vehicles that may intrude on the crossing.
