traveler sourced updates Quintuple

Bidirectional?: False

traveler sourced updates (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between two application objects: 'Personal Interactive Traveler Information', and 'DDS Data Collection and Aggregation'. 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 'traveler sourced updates'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Personal Information Device' to 'Data Distribution System'.

Personal Information Device (Source Physical Object): The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with connected vehicle on-board equipment.

Personal Interactive Traveler Information (Source Application Object): "Personal Interactive Traveler Information" provides traffic information, road conditions, transit information, yellow pages (traveler services) information, special event information, and other traveler information that is specifically tailored based on the traveler's request and/or previously submitted traveler profile information. It also supports interactive services that support enrollment, account management, and payments for transportation services. The interactive traveler information capability is provided by personal devices including personal computers and personal portable devices such as smart phones.

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.
