9.3.1.1: Operate Work Zone Devices
This process shall monitor, operate, and control devices located at or alongside the roadway that monitor and control traffic in areas with construction, maintenance, or utility work activities. The devices operated include driver information devices (e.g. dynamic message signs and highway advisory radio), imaging devices (e.g. closed circuit television), traffic sensors, barriers (e.g. gates), and work zone intrusion detection and alert devices. This process shall collect the operational status (state of the device, configuration, and fault data) from each of the devices.
This process is associated with the Maint and Constr Management Center physical object.
This process is associated with the following functional objects:
- MCM Reduced Speed Zone Warning
- MCM Traffic Information Dissemination
- MCM Work Zone Management
- MCM Work Zone Safety Management
