traffic gap coordination information Quintuple

Bidirectional?: True

traffic gap coordination information (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'Vehicle Gap Assist', and 'RSE Traffic Gap Assist'. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

Vehicle OBE (Source 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 Gap Assist (Source Application Object): "Vehicle Gap Assist" uses V2I communications to collect traffic gap information and associated alerts and warnings that are displayed to the driver who is navigating a stop-sign controlled intersection with a major road.

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 Traffic Gap Assist (Destination Application Object): "RSE Traffic Gap Assist" provides advisory information to minor road drivers at a stop-sign controlled intersection to facilitate gap selection to proceed through the intersection. The application can be configured depending on the intersection geometry. It monitors Connected Vehicle traffic on the major road, augmenting infrastructure traffic detectors, to identify and measure traffic gaps. The intersection geometry, measured traffic gaps, and current gap assist sign displays are communicated to the connected vehicle that is navigating the intersection for use in driver advisories and warnings. The application may also collect vehicle size and performance profile from the connected vehicle to optimize the alerts and warnings to the capabilities of the vehicle and driver preferences.
