Model Minimum Uniform Crash Criteria (MMUCC)

Everything you wanted to know about MMUCC

MMUCC Evolution

Prior to 1998, there was no standardized listing of data elements that states should collect.

In 1996, NHTSA approached GHSA about working on a project to develop a voluntary guideline consisting of a minimum set of data elements

FHWA and FMCSA were active partners An expert panel was formed and met four times in

1997. A one-day national conference was held in

conjunction with 1997 Traffic Records Forum. First edition of MMUCC was published in 1998.

MMUCC Evolution

Since 1998, states have had experience implementing MMUCC and know what data elements work and what needs to be changed

New issues have emerged such as distracted driving, booster seats, low speed vehicles, etc.

As a result, it was time to reexamine MMUCC and make revisions

Intent is to update MMUCC every five years

MMUCC Evolution

Work on 2nd edition (2003) began in 2002 NHTSA undertook data compatibility study. Results

of study served as input to MMUCC update effort FHWA and FMCSA were active partners A new expert panel was formed and met twice A one-day national meeting was held in conjunction

with Traffic Records Forum MMUCC was placed on web and interested persons

could submit comments 2nd edition (2003) was published in June

MMUCC Purpose

To provide a minimum, standardized data set for describing crashes of motor vehicles that will generate the information necessary to improve highway safety within each state and nationally.

Uses of MMUCC data

MMUCC data can be used to identify priority highway safety problems, select countermeasures, monitor progress, evaluate impact, suggest changes to vehicle design and support federal decision-making

Comparable state data can be used to identify trends and issues

Comparable data enables interstate comparisons and interstate solutions to highway safety problems

Miscellaneous MMUCC Facts

Each MMUCC data element includes a definition, set of attribute values and a rationale.

MMUCC uses existing standards documentation from ANSI D16.1, ANSI D20.1, FARS, NASS and FMCSA mandated data elements

No attempt to organize the data elements or recommend a particular reporting form

MMUCC data elements are collected at scene, derived, or obtained through linkage. States that have difficulty linking can collect data at scene

The data elements are VOLUNTARY. There are no MMUCC police!!

Reporting Thresholds

All crashes statewide involving death, personal injury or property damage of $1,000 or more should be reported

Crash data should be reported for all persons involved (including injured and non-injured)

Each state should adopt a reporting threshold that is consistent and uniformly implemented statewide

Next Steps

NHTSA will be funding implementation activities including web-based training, marketing materials, roll call video for law enforcement, surveys of state implementation, best practices guides, etc.

MMUCC 2nd edition (2003) data elements will be incorporated into TraCS software

Interested persons encouraged to submit comments on MMUCC website, www.mmucc.us

MMUCC will be revised again in 2007 with publication in 2008
