| 摘要： | The Traffic Management Data Dictionary (TMDD) and Message Sets for External Traffic Management Center Communications Standards work together to provide a high level of interoperability among regional and local systems/centers. The Traffic Management Data Dictionary Standard provides consistent names, definitions, and concepts to the data elements in the Standard. The Traffic Management Data Dictionary enables concepts from traffic management to be defined and used in the same way by different systems and centers. However, the Standard also anticipates and provides for the use of locally unique data elements to recognize the individuality of each system or center. The Message Sets for External Traffic Management Center Communications Standard uses these data elements by combining them together in a sentence-like way in the sharing of data or pre-defined typical messages between systems or centers. These two standards provide a framework for interoperability that is consistent with the Intelligent Transportation Systems (ITS) Architecture and work in conjunction with other standards, such as the Standard for Data Dictionaries. |
