Link Type: Position Location Interface

Field Location and Time Data Source --> Roadside Equipment:
location and time


location and time (Information Flow): The current geographic location in three dimensions (latitude, longitude, elevation) and the current time.

Field Location and Time Data Source (Source Physical Object): The 'Field Location and Time Data Source' provides accurate position information for field devices such as Roadside Equipment (RSE). 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.

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.
