Overview

This High-level Function shall provide facilities for the management of incidents that occur within a road network.  It shall be possible for the incidents to be planned, or due to a variety of un-planned events.  The Function shall enable the occurrence of these unplanned incidents to be detected by internal functionality, or by other Functional Areas.  It shall be possible for the Function to involve these and other Functional Areas in the management of incidents through implementation of planned activities that are part of incident management strategies.

    The Functions use the definition of an "incident" which says that it is an out of the ordinary occurrence. Therefore normal peak travel congestion does not qualify as an "incident" unless it is made worse by some other event. This may be planned, e.g. a parade, or be due to a random event such as a road traffic accident, or a major fire in a building next to part of the road network.

    Between each of these Functions there are some Data Flows. A minority of these enable the Functions to exchange data with each other. However the vast majority enable the Functions to exchange data with other parts of the Manage Traffic Area, with other Areas and with the terminators. The Functions and Data Flows are contained in the DFD for Function 3.2 - DFD 3.2.
