location and time Quintuple

Bidirectional?: False

location and time (A-Interconnect): This CVRIA application interconnect encapsulates all of the Layer 2 information flows between the 'Personal Support Services' application object and the 'Personal Location and Time Data Source' 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 'location and time'. This application interconnect is uni-directional since the underlying layer 2 information flows go from 'Personal Location and Time Data Source' to 'Personal Information Device'.

Personal Location and Time Data Source (Source Physical Object): The 'Personal Location and Time Data Source' provides accurate position information for personal mobile devices. While a Global Positioning System (GPS) Receiver is the most common implementation, this physical object represents any technology that provides a position fix in three dimensions and time with sufficient accuracy.

Personal Information Device (Destination 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 Support Services (Destination Application Object): 'Personal Support Services' provides foundational functions that supports data collection, management, and distribution. It coordinates with Object Registration and Discovery to maintain its registration with respect to location/geographic scope and credentialing information. It maintains the necessary security credentials, authorizations, and associated keys to support communications in the connected vehicle environment.
