9.2.6.2: Control Roadway Automated Treatment System

This process shall automatically treat a roadway section based on environmental or atmospheric conditions as determined from environmental sensors under its control. Treatments can be in the form of fog dispersion, anti-icing chemicals, etc. This process shall send treatment information to another function for roadway information device (e.g. dynamic message sign) display to drivers. Control information for the environmental sensor and automated treatment equipment is received from another process. Operational status (state of the device, configuration, and fault data) of the automated treatment system, including activation occurrences, is returned to that process and to another process to arrange for repair if deemed necessary.

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