1.2.7.10.1: Control Barrier Systems

This process shall automatically activate barrier systems, such as gates, barriers, and other automated or remotely controlled systems used to manage entry to roadways upon receiving configuration and control commands from other processes. The process shall accept inputs to control the barrier systems and return operational status (state of the sensor device, configuration, and fault data) to the controlling process as well as to a Manage Maintenance and Construction process for repair. This process shall support access requests to open a barrier or gate. This process shall maintain the necessary authentication configuration data pertaining to the field devices being controlled. Once access is granted or denied this process shall notify the requesting process. This process shall send activation information to another function for roadway information device (e.g. dynamic message sign, in-vehicle signage) display to drivers.

This process is associated with the ITS Roadway Equipment physical object.
