This Function shall be capable of providing the following facilities:<br/><br/>(1) The ability to manage the traffic using one or more bridges that are located on the road network served by the System.<br/>(2) The ability to monitor one or more bridges that are located on the road network served by the System. <br/>(3) The ability to collect weather and other conditions on the bridge(s) that it is managing using its own sensors and receive weather forecasts for the local geographic area(s) around the bridge(s).<br/>(4) The ability to automatically initiate action when conditions likely to endanger the traffic using the bridge(s) are detected, using actions that have been previously defined by the Bridge Operator, including the output of messages to Drivers either directly on the bridge or through other roadside equipment.<br/>(5) If no action is defined, the ability to use the Bridge Operator HMI provided by other functionality to present the Operator with options for actions to be taken that must either be accepted or amended before they are implemented.<br/>(6) The ability to send both the actions taken and details about the dangerous conditions as an incident to the relevant part of other functionality in the System.<br/>(7) The ability to also receive the details of the content of messages informing Drivers about traffic management strategies that it should output to Drivers using the bridges(s) that it is managing in the absence of any higher priority messages of its own once confirmation is received from the Bridge Operator.<br/>(8) If any faults are detected by its sensors or other equipment, the ability to report this to the appropriate functionality in the System.<br/>
(a) continuously monitor for receipt of the input data flows;<br/>(b) when the bridge action definitions data flow is received in (a) without there having been any outputs to the bridge operator with requests for action definitions, store its contents for future use;<br/>(c) when the weather for bridges data flow, or current status data flow is received in (a) store its contents for future use;<br/>(d) continuously scan the bridge weather conditions data flow and use sensors to determine the current atmospheric conditions at the bridge, e.g. temperature, wind speed and direction, precipitation and visibility and store the result for future use;<br/>(e) periodically analyse the data collected in (b) and (c) and determine the effect that the current and forecast weather conditions will have on traffic using the bridge;<br/>(f) if the result of (e) is that the passage of vehicles across the bridge will be endangered, implement the most appropriate action received in (b), through sending the contents of messages to Drivers in the bridge information outputs data flow to the Output Bridge Information to Drivers function, sending similar message contents for output to Drivers in the bridge inter-urban inputs and bridge urban inputs data flows to the Implement Inter-urban Traffic Commands and Implement Urban Traffic Commands functions respectively;<br/>(g) in addition to (f) create an incident report, put it in the data flow and send it to the Classify and Identify Incidents function;<br/>(h) if input is no longer detected in (b) or (c) send the bridge equipment status message with a fault indication to the Evaluate Need for Equipment Maintenance function.<br/>
