By facilitating the exchange of transportation information between organizations, the Surface Transportation subcommittee helps enhance the safety of our nation’s transportation systems. It promotes improved decision-making through increased data quality, more efficient and secure data exchange, and accelerated adoption of data standards – which also improves the quality of agency open data efforts.


The Surface Transportation subcommittee was launched in September 2015 under the stewardship of the U.S. Department of Transportation (DOT)’s Chief Data Officer (CDO). While governance activities will continue to evolve as the subcommittee matures, the initial scope of the Surface Transportation subcommittee will focus on an existing community of interest: the DOT Traffic Records Coordinating Committee and the State Traffic Records Coordinating Committees.

The initial NIEM model content for Surface Transportation was included in the NIEM 3.2 release. NIEM 3.2 changes updated the Model Minimum Uniform Crash Criteria (MMUCC) content to match version 4.0 of the MMUCC guideline. In addition, it realigned a number of data elements - previously found elsewhere in the model - that are used to describe roadway characteristics to the Surface Transportation subcommittee.
