Low Level Function
3.1.6.6 Process Traffic Prediction Results

Overview

This Function shall be capable of providing the following facilities:

(1) The ability to receive from the functionality managing the store of Traffic Simulation Data the results of a simulation that have been produced by the Traffic Simulation Engine functionality.
(2) The ability to process these results to provide coherent and comprehensive information about forecasts of traffic conditions and traffic management strategies.
(3) The ability to automatically send this information to the appropriate functionality in the System.

Functional Requirements

(a) monitor for the receipt of the traffic simulation results for processing data flow
(b) when the data flow in (b) is received, process the data it contains to produce and send each of the output data flows
(c) include in the forecast traffic conditions data sent to the traffic and travel information provider data from which a traffic model can be produced.

    Description

    7.1.2.8
    The system shall be able to produce new traffic management strategies from one or more of historic, current, or predicted road traffic data.
    7.5.1.11
    The system shall be able to provide the driver, via an in-vehicle device, and on request, details of the (predicted) traffic situation in a defined area of interest, and for a time horizon, that has been selected by the driver.  This information shall be updated at (selected) intervals.
    7.5.1.24
    The system shall be able to calculate a predicted time for a total journey made up from separate links.  The predicted time shall be updated regularly as the time for each link changes.
    7.6.2.5
    The system shall enable the traveller information service provider to be provided with current an predicted inter-urban traffic conditions.
