queue warning information Quintuple

Bidirectional?: False

queue warning information (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'RSE Queue Warning', and 'Vehicle Queue Warning'. In this case, there is only a single Layer 2 flow associated with this interconnect, so the Layer 1 application interconnect name and the Layer 2 information flow name are both 'queue warning information'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Roadside Equipment' to 'Vehicle OBE'.

Roadside Equipment (Source 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 Queue Warning (Source Application Object): "RSE Queue Warning" provides V2I communications to support queue warning systems. It monitors connected vehicles to identify and monitor queues in real-time and provides information to vehicles about upcoming queues, including downstream queues that are reported by the Traffic Management Center.

Vehicle OBE (Destination Physical Object): The Vehicle On-Board Equipment (OBE) provides the vehicle-based processing, storage, and communications functions necessary to support connected vehicle operations. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. This communication platform is augmented with processing and data storage capability that supports the connected vehicle applications.

In CVRIA, the Vehicle OBE includes the functions and interfaces that support connected vehicle applications for passenger cars, trucks, and motorcycles. Many of these applications (e.g., V2V Safety applications) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle OBE includes the common interfaces and functions that apply to all motorized vehicles.

Vehicle Queue Warning (Destination Application Object): "Vehicle Queue Warning" detects vehicle queues and reports queues to other vehicles using V2V communications and to the infrastructure using V2I communications. Vehicle-based queue warning builds on the exchange of vehicle location and motion and maneuvers that supports connected vehicle safety applications. This application also receives information about downstream queues using I2V communications. Individualized queue warnings and queue characteristics relevant to the vehicle are provided to the driver.
