Overview

This Function shall be capable of providing the following facilities:

(1) The ability to create short and medium term predictions of inter-urban traffic data.
(2) The ability to create the predictions of short and medium term inter-urban traffic data using algorithms that may be different in content and scope.
(3) The ability to request and use current inter-urban traffic data as the starting point for the predictions of short and medium term inter-urban traffic data.
(4) The ability to repeat the creation of the predicted short and medium term inter-urban traffic data at (frequent?) periodic intervals.

Functional Requirements

(a) at (frequent?) periodic intervals send the data flow containing the request iner-urban traffic data to the Manage Inter-urban Traffic Data function
(b) as a result of (a) continuously monitor for the receipt of the data flow containing the requested inter-urban traffic data
(c) when the data flow in (b) is received, create the predictions of short and medium term inter-urban traffic data using appropriate algorithms that may be different in content and scope
(d) when (c) is complete, put the results in the short & medium predicted inter-urban traffic data flow and send it to the Manage Inter-urban Traffic Data function.
