driver updates Quintuple

Bidirectional?: False

driver updates (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'Vehicle Rail Crossing Warning' application object and the 'Driver' physical object. 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 'driver updates'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Vehicle OBE' to 'Driver'.

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 Rail Crossing Warning (Source Application Object): "Vehicle Rail Crossing Warning " uses I2V communications to receive alerts of trains entering HRIs and to provide warnings to drivers regarding the trains. The warning can include second train warning (meaning the HRI gates are about to lower, or remain lowered due to the arrival of a second train). The application can also provide vehicle infringement warnings by using the alert information along with vehicle trajectory information to determine that the vehicle will infringe upon a crossing that is (or will be) occupied by a train.

Driver (Destination Physical Object): The 'Driver' represents the person that operates a vehicle on the roadway. Included are operators of private, transit, commercial, and emergency vehicles where the interactions are not particular to the type of vehicle (e.g., interactions supporting vehicle safety applications). The Driver originates driver requests and receives driver information that reflects the interactions which might be useful to all drivers, regardless of vehicle classification. Information and interactions which are unique to drivers of a specific vehicle type (e.g., fleet interactions with transit, commercial, or emergency vehicle drivers) are covered by separate objects.
