t_other_rw_dms_barrier_activated_from_roadway
This data flow from an automated barrier system causes a roadway information device such as a dynamic message sign (DMS) to display an indication of the status of the barrier system (e.g. open, closed). 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:
