1.2.4.2: Output Control Data for Freeways
This process shall transfer data to processes responsible for controlling equipment located at the roadside within the freeway network served by the Manage Traffic function. The traffic metering devices remotely controlled by this process could include ramp, interchange, tunnels, mainline meters, HOV lane usage signals, HOV lane control systems, and reversible lane facilities equipment required to change the direction of traffic flow along a freeway system. Data for use by in-vehicle signage equipment shall be sent to another process for output to roadside processes. This process shall also be responsible for the monitoring of input data showing the way in which the indicators are responding to the data that they are being sent, and the reporting of any errors in their responses as faults. The reported data shall include the operational status (state of the device and configuration) from the indicator device. All output and input data shall be sent by the process to another process in the Manage Traffic function to be loaded into the store of long term data.
This process is associated with the Traffic Management Center physical object.
This process is associated with the following functional objects:
