5.7.6.2: Manage Safeguard Systems

This process shall remotely monitor and manage safeguard systems, equipment used to mitigate the impact of incidents on transportation infrastructure (e.g., blast shields, tunnel exhaust systems, etc.). The process also outputs data to other processes within Manage Traffic to control dynamic message signs (DMS), highway advisory radio (HAR), or in-vehicle signage used to inform travelers of safeguard system activation. Activation requests shall be accepted from other processes including a process that manages emergency response and the center personnel interface process. Operational status (state of the device, configuration, and fault data) about the safeguard system equipment shall be collected and forwarded to the processes that requested activation and to a process that handles detours. The information will also be forwarded to another process for archival.
