Overview

This Function shall be capable of providing the following facilities:

(1) The ability to create short and medium term predictions of urban traffic data.
(2) The ability to create the predictions of short and medium term urban traffic data using algorithms that may be different in content and scope.
(3) The ability to request and use current urban traffic data as the starting point for the predictions of short and medium term urban traffic data.
(4) The ability to repeat the creation of the predicted short and medium term 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 Urban Traffic Data function
(b) as a result of (a) continuously monitor for the receipt of the data flow containing the requested urban traffic data
(c) when the data flow in (b) is received, create the predictions of short and medium term 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 urban traffic data flow and send it to the Manage Urban Traffic Data function.
