This process posts safe speed limits to passing motorists through use of such means as variable speed limit signs, in-vehicle signing functions, highway advisory radio broadcasts. These safe speed limits are defined by the Set Speed Limit function but they may also gather input from the local roadway conditions to determine the safe speed based on weather or other environmental conditions from the Process Roadway Warning Data function. The safe speed is also output to the function to Detect and Classify Speed Violations to use to enforce the new speed limit.
