The Model Minimum Uniform Crash Criteria (MMUCC) is a minimum, standardized data set for describing motor vehicle crashes and the vehicles and persons involved. By providing a "minimum" set of data elements, MMUCC helps states collect reliable crash data, effectively guide enforcement planning, and shape sound traffic safety policy. This data set, originally published in 1998, has been revised three times, most recently in the 4th Edition (2012), in response to emerging highway safety issues. GHSA has helped manage these updates with funding from the National Highway Traffic Safety Administration (NHTSA).
GHSA and NHTSA have embarked on a project to update MMUCC. With new vehicle technologies being developed rapidly, the transition to MMUCC’s 5th edition offers an important opportunity to move the standard forward, streamlining frontline data collection and providing flexibility for data collectors and managers alike as vehicles and the driving environment continue to evolve. Highway safety professionals were able to provide input on these proposed changes in 2016 via an online forum developed by GHSA and NHTSA.
GHSA worked with NHTSA to help states determine how well each state's Police Accident Report (PAR) and crash database aligns with the Model Minimum Uniform Crash Criteria (MMUCC) 4th edition and to develop a new tool to help states map their state PARs and crash databases to the 77 MMUCC data elements and attributes collected at the scene of a crash and the 33 data elements and attributes that are linked with other databases or derived from MMUCC data elements.
The resulting document, Mapping to MMUCC, was piloted in two states, New Jersey and Utah, and feedback was incorporated into the final version of the document. The results from this mapping process, along with additional feedback received from states during the development process, will be used to revise the existing MMUCC elements and the mapping process methodology will be incorporated into the Fifth Edition of the MMUCC Guideline.
