Overview

This Function shall be capable of providing the following facilities:

(1) The ability to evaluate the short term maintenance needs of the road network and to request any needed repair activities.
(2) The ability to use the data to determine the need for a warning to be issued to Drivers, and when these are required, the ability to send them to other functionality in the System.
(3) The ability to use data about the amount of traffic that has been using the road network and weather information to evaluate its maintenance needs.
(4) The ability to compare this data about the amount of traffic that has been using the road network and weather information with the parameters for activating short term maintenance activities and from this recommend the most appropriate activities to be carried out.
(5) If the recommended short term maintenance activities are confirmed by the Road Maintenance Operator then the ability to request the Maintenance Organisation to carry out the work.
(6) If the recommended short term maintenance activities are confirmed by the Road Maintenance Operator, the ability to send information about these activities to the Trip Planning and Incident Management functionalities as the maintenance activities will affect traffic and because they are roadworks.
(7) The ability to keep a record of the current status of the requested short term maintenance activities, which shall be updated using the input from the Maintenance Organisation.
(8) The ability to send the current status of the requested short term maintenance activities to the Maintenance Data Store so that it can be accessed by the Road Maintenance Operator through their HMI.

Functional Requirements

(a) continuously monitor for the receipt of the short term maintenance conditions data flow
(b) continuously gather data in the short term wearing state data flow
(c) use the data collected in (a) and (b) to assess the need for short term road maintenance
(d) if short term road maintenance is needed, determine its precise location using data from the inter-urban and urban road static data for short term maintenance data flows
(e) as a result of (c) and (d) send the confirm short term maintenance data flow to the Provide Road Maintenance Operator Interface function
(f) as a result of (e) continuously monitor for receipt of the short term maintenance confirmed data flow
(g) when the data flow in (f) is received, send the instructions for the short term maintenance work to the maintenance organisation in the short term activities data flow and send the details in the confirmed short term maintenance activity data flow to the Provide Maintenance Data Store Management function
(h) also when the data flow in (f) is received, send details of the maintenance work activities to other functionality in the short term maintenance data and short term maintenance conditions data flows
(i) as a result of (g) continuously monitor for receipt of the short term maintenance activity update data flow from the maintenance organisation
(j) when the data flow in (i) is received, repeat (h) with updated information and update the data about the activities in the store of Maintenance Data using the update short term maintenance activity data flow
(k) whenever either the inter-urban or urban road static data for short term work data flows is received, store its contents locally for use in (d) above.
