vehicle situation data Quintuple

Bidirectional?: True

vehicle situation data (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'Vehicle Situation Data Monitoring', and 'DDS Data Collection and Aggregation'. 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 Situation Data Monitoring (Source Application Object): "Vehicle Situation Data Monitoring" is the highest-level representation of the functionality required to collect traffic and environmental situation data by monitoring and storing the experience of the vehicle as it travels through the road network. Collected data is aggregated into snapshots that are reported when communications is available and with flow control based on parameters provided by the infrastructure. Note that this application object supports collection of data for areas remote from RSEs or other communications infrastructure.

Data Distribution System (Destination Physical Object): The 'Data Distribution System' collects, processes, and distributes connected vehicle data, connecting data producers with data consumers and facilitating data exchange in the Connected Vehicle Environment.

DDS Data Collection and Aggregation (Destination Application Object): "DDS Data Collection and Aggregation" collects data "deposits" from producers including meta data such as the generation location and time. It authenticates and validates the data deposits and logs all associated meta data. Authenticated, valid data is bundled based on information type and location and made available as data products to consumers who are interested in the data. It establishes delivery parameters for data consumers that subscribe based on parameters including content type and geographic region of interest and delivers data to consumers based on these parameters.
