This is a DFD diagram which provides a description of the function in the ITS environment

Overview

This High-level Function shall provide the facilities needed to manage the maintenance of the infrastructure that comprises the inter-urban and urban road network.  This shall include the physical pavement and any equipment used to manage the use of the road network.  When it is found that short term, long term maintenance or repair work is needed, the Function shall obtain confirmation from the Operator before requesting the Maintenance Organisation to carry out the work.  This work shall also include the de-icing or the road surface when the Function determines that it is needed.

    The Functions gather data about the use being made of the road network, local road and pavement surface conditions and equipment functioning. This data is analysed and used to instruct the Maintenance Organisation to carry out maintenance and/or repair work, and to apply de-icing treatment when conditions demonstrate it is needed.

    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 3.5 - DFD 3.5.
