This Function shall be capable of providing the following facilities:<br/><br/>(1) An HMI through which the Bridge Operator can monitor and manage the operation of bridges in the road network managed by the System.<br/>(2) The ability of the HMI to enable the Bridge Operator to be informed of any dangerous weather conditions that have been detected, e.g. high winds, low temperatures and poor visibility, and of the action being automatically taken in response.<br/>(3) If the Bridge Operator is advised that there are no pre-defined actions that can be taken, the HMI shall enable them to be defined by the Operator for immediate implementation.<br/>(4) The ability for the Bridge Operator to set up actions in advance of the detection of any dangerous weather conditions.<br/>
(a) continuously monitor for receipt of data flows from the Bridge Operator;<br/>(b) when the data flow in (a) is received, check its contents and if they list the actions taken, output them to the Bridge Operator in the dangerous weather conditions action taken data flow;<br/>(c) as a result of (b) continuously monitor for receipt of the weather condition action request response data flow and when it is received send its contents to the Asses Bridge Status and Take Action function in the bridge action responses data flow;<br/>(d) if the data flow in (a) contains a request for new actions to be provided, send this to the Bridge Operator in the dangerous weather conditions action request data flow;<br/>(e) as a result of (d), monitor for receipt of the bridge action definitions data flow from the Bridge Operator;<br/>(f) when the data flow in (e) is received, send the new actions to the Assess Bridge Status and Take Action function in the bridge action definitions data flow;<br/>(g) continuously monitor for receipt of the bridge action definitions data flow from the Bridge Operator;<br/>(h) when the data flow in (g) is received, send its contents to the Assess Tunnel Status and Take Action function in the Bridge Operator action responses data flow.<br/>
