摘要：	Three key components have been conceived for a national spatial data interoperability framework to support ITS products and systems. The first component is the Location Reference Message Specification (LRMS), a specification of standard location reference message formats (termed 'profiles') for public and private users. The second component is the development of a US national ITS Datum, a national standard network of ground control points that will anchor spatial references between databases of different kinds. The third component is a spatial dataset transfer standard for ITS, a specification of an intermediate dataset format and common descriptive language for ITS dataset transfers. The LRMS and ITS Datum components have been developed by FHWA projects funded through Oak Ridge National Laboratory (ORNL). Working together, the LRMS and ITS Datum concepts support many applications and kinds of location referencing, including the GIS-T community and linear referencing. Testing activities are in process under current activities at ORNL and its subcontractors. SAE is pursuing standardization of the LRMS itself, and the ITS Datum is being developed as a public domain dataset. This paper discusses the LRMS, the status of current testing activities, and future test initiatives leading to national deployment for ITS location referencing. It is noted that, while many testing activities for technologies and standards can be performed in conjunction with other ITS activities, such as the Model Deployment Initiatives (MDIs), true national interoperability tests that cross the spatial and institutional boundaries of such local and isolated tests must be conducted.
