The Association of Transportation Safety Information Professionals (ATSIP) has embarked upon the effort of updating the development of consensus-based standards (ANSI D16.1-Manual on Classification of Motor Vehicle Traffic Accidents, last reviewed in 2007 (7th Edition)). This standard strives to promote uniformity amongst all crash data collectors and agencies, and thereby, promote and improve traffic safety nationwide. The effort to promulgate standards that may be used by agencies and their employees throughout the country will be the result of the collaboration of a national forum, which signifies to all parties who are materially impacted by the standard that it is the desire and intent of ATSIP to produce standards that promote enhanced traffic safety for all roadway users.

The Association of Transportation Safety Information Professionals (ATSIP) is a non-profit organization whose mission is to provide a forum for communicating traffic records improvement strategies among all interested disciplines, organizations, and governments and to use its combined expertise to recommend strategies, standards, policies and programs. ATSIP’s goal is to improve the quality of traffic records – to make them timely, accurate, consistent, complete, accessible and integrated – and to encourage their use to select, implement and evaluate safety programs and policies through the United States and the world.

Law enforcement, vital statistics, and other government agencies, vehicle manufacturers, medical personnel, and legislative bodies have vested interests and legal responsibility related to the incidence and reporting of motor vehicle crashes and the resulting damage, injuries, fatalities, and personal and societal costs. As a result, for decades, data regarding motor vehicle crashes has been shared among these various agencies and entities, in an effort to determine means by which to mitigate and eventually eliminate crashes nationwide. 

Crash data has been analyzed in order to identify driver demographics and risky behavior, types of roadway configurations where crashes are most likely to occur, emergency medical intervention most successful in saving lives, and vehicle types which may be over-represented in crashes.  These analyses have provided data used successfully in education, engineering, EMS, and enforcement efforts to reduce both the number and severity of crashes that occur. 

Data about crashes originates in all 50 states plus the District of Columbia and the U.S. Territories, and is captured by thousands of law enforcement agencies, and their officers and employees. The analytical potential of these crash reports lies in their ability to be aggregated for research and reporting, which is dependent upon standardization and uniformity of reporting and data-capture across states and agencies.

The effectiveness of crash countermeasures is directly dependent upon reliable and accurate traffic records data.

ATSIP’s organization consists of an executive Board and professional members. Its activities are supported by governments, academic and professional associations, and private sector partners. Membership is open to any person with an interest in traffic safety who has experience with data, or is actively involved in the design, development, maintenance and/or operation of transportation safety information systems or in their administration and use. This includes traffic safety data collectors, users, and managers.

Complete records of all discussion board interactions will be kept, including names of those who participated and any voting conducted through this board, including an affirmative statement that notice was given as to the dates of votes to be taken on the discussion board, including that a quorum participated; and a record of each participant’s vote.

We invite you to participate in the ANSI D16 Public Discussion Board. If you are not an ATSIP member, and you wish to participate, you will need to register an account on the ATSIP Discussion Board at will be no costs associated with general public discussion board participation. If you having an issues with registration, please email

Some key items are missing from the "Announcement"

1> D16.1-2007 was from NSC, So is it correct to assume that NSC has shifted D16.1 to ATSIP?

2> What is ATSIP relationship with ANSI? E.g., Is ATSIP 'certified' by ANSI for D16.1?
          You need ANSI 'approval' before you can do a D16.1 update.

3a> What is D16.1 update deadline or time frame?  "Announcement" contains no schedule.
              Forum has been inactive for ~ 6months.
3b> Has ATSIP dropped D16.1, in favor of something else? For example MMUCC development?

NOTE: While D16.1 is restricted to US traffic records, the ISO/ ISO/TC22/SC36/WG7, Traffic accident analysis methodology, has developed several related international standards (below). Since ANSI represents the US within ISO/TC22, Road vehicles, it is important to retain consistent terms and classifications. This remains a key goal for me, as a US/SAE ANSI member of WG7.
        ISO 6813:1998(E/F) Road vehicles — Collision classification — Terminology
        ISO/CD 12353-1:2017(E) Road vehicle — Traffic accident analysis — Part 1: Vocabulary

Thank you for your inquiries.

1. Yes, the previous edition of ANSI was developed under the auspices of the National Safety Council. However, shortly after its development, the ANSI D.16 was allowed to lapse, and has not been a national standard for some years.

2. ATSIP has a contract through NHTSA to regain ANSI certification for the D.16 standard. Yes, ATSIP has been certified as a standards developer, and has developed an 8th edition of the Classification of Motor Vehicle Traffic Crashes document. 

 3a. The standard has been announced in Standard Actions, and is now going through voting with the Consensus Panel. After final editing, it will be posted once again through ANSI in Standard Actions and hopefully will once again become a national standard within the next 60 days. A 5th edition of MMUCC is being developed as well and will be consistent with ANSI definitions.  

We do understand that ANSI standards must be consistent with ISO standards and will review the standards noted to ensure consistency.

Joan vecchi,
Project Manager
