f_other_rw_dms_safeguard_activated_from_roadway

This data flow from an automated safeguard system (e.g. blast shields, exhaust fans) causes a roadway information device such as a dynamic message sign (DMS) to display an indication of the status of the safeguard system (e.g. ongoing, just completed, about to begin). The data flow may contain the actual data from which instructions to the driver and traveler can be produced by roadway information devices or it may contain a message code that causes a specific display. It consists of the following data items each of which is defined in its own DDE:

list_size
+ list_size{indicator_identity
+ dms_advisory_text + lane_dms_controls}
