1.2.4.5: Manage Barrier Systems

This process shall remotely monitor and manage barrier systems, such as gates, barriers, and other automated or remotely controlled systems used to manage entry to roadways. The process also outputs data to dynamic message signs (DMS) used to inform travelers of barrier activation. Activation requests shall be accepted from other processes including a process that manages emergency response, a process that handles detours, and the center personnel interface process. Operational status (state of the device, configuration, and fault data) about the barrier system equipment shall be collected and forwarded to the processes that requested activation. The information will also be forwarded to another process for archival.

This process is associated with the Traffic Management Center physical object.
