local situation data Quintuple

Bidirectional?: True

local situation data (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'DDS Data Collection and Aggregation', and 'RSE Situation Monitoring'. This application interconnect is bi-directional since the underlying layer 2 information flows carry data in both directions.

Data Distribution System (Source 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 (Source 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.

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 Situation Monitoring (Destination Application Object): "RSE Situation Monitoring" is a general application object that supports collection of traffic, environmental, and emissions data from passing vehicles. The data is collected, filtered, and forwarded based on parameters provided by the back office. Parameters are provided to passing vehicles that are equipped to collect and send situation data to the infrastructure in snapshots. In addition, this object collects current status information from local field devices including intersection status, sensor data, and signage data, providing complete, configurable monitoring of the situation for the local transportation system in the vicinity of the RSE.
