1.2.7.2: Monitor Roadside Equipment Operation
This process shall monitor the operation of the indicators in the road (surface street) and freeway network. It shall report any instances where the indicator response does not match that expected from the contents of the indicator control data it is receiving, and is verified against known indicator preemptions. A report shall be output by this process if equipment failure is detected and sent to another process in the Manage Traffic and Manage Maintenance and Construction functions to arrange for repair. The report shall also include the operational status (state of the device and configuration) from the indicator device. This process also supports an interface to a managing center to provide device identity and configuration management data in order to manage the permission of certain applications on the roadway equipment (e.g. signal preemption only by authorized agency vehicles).
This process is associated with the ITS Roadway Equipment physical object.
This process is associated with the following application objects:
- Roadway Basic Surveillance
- Roadway Communications Support
