1.2.4.7: Manage Roadway Warning System
This process shall remotely monitor and control the roadway warning systems that detect potential roadway hazards (e.g., roadway weather conditions, road surface conditions, traffic congestion and queues, obstacles in the roadway, oversize vehicles) and provide warnings to drivers, bicyclists, and pedestrians. This process shall pass configuration and control parameters from traffic operations personnel for autonomous operation by field equipment. In addition, this process shall pass traffic images and processed traffic information from the roadway to another process where it is presented to traffic operations personnel. Upon receipt of direction from traffic operations personnel, this process shall pass control information to roadway warning systems to activate warning signals.
This process is associated with the Traffic Management Center physical object.
