The Development of Crash Modification Factors (DCMF) Program - Studies

 

The Federal Highway Administration (FHWA) Development of Crash Modification Factors (DCMF) program was established in 2012 to address highway safety research needs for evaluating new and innovative safety strategies (improvements) by developing reliable quantitative estimates of their effectiveness in reducing crashes.

The DCMF Program Studies

Enhancing Statistical Methodologies for Highway Safety Research – Impetus from FHWA

This study was completed in March 2014 and will be published in the summer of 2014. The goal of this project was to:

  • Identify new statistical methodologies.

  • Improve and advance the current methodologies used in the development of safety performance functions (SPFs) and crash modification factors (CMFs).

  • Recommend an initial set of reliable and time/labor efficient methodologies that can be used by FHWA and State departments of transportation and other transportation agencies for SPF and CMF development.

Working toward these goals, the project team, in consultation with FHWA, planned a two-day technical experts (TE) meeting to bring together researchers from the road safety, statistics, and other statistics-related fields such as epidemiology, biostatistics, and agent-based models that have methodologies relevant to highway safety research applications. The meeting was arranged to work with attendees to identify applicable advanced methodologies and/or improve existing methodologies for the development of SPFs and CMFs.

This effort will be continued by followup studies, and by implementing a marketing, communication, and outreach plan (MCOP) targeting the statistician community for developing new expertise, technical tools, and innovative highway transportation specific methodologies.

CMF Needs Assessment (Ongoing)

The above study will be completed in June 2014, and its findings will be published in the summer of 2014.

The Enhancing Statistical Methodologies for Highway Safety Research – Impetus from FHWA was conducted to build a foundation for advancing highway safety research by finding new methodologies and improving the existing ones. This CMF needs assessment study presents the second step towards these goals. This effort is to conduct a gap analysis of CMFs, identify current and future research needs, and conduct a meeting for communicating to and with CMF stakeholders. 

The objectives of the CMF needs assessment study are to:

  • Conduct a CMF gap analysis study that will:

    • Inventory existing CMFs.
    • Identify CMF research needs.
    • Prioritize future CMF research needs and development efforts.

  • Arrange and facilitate a stakeholder meeting that will be conducted in the following order:

    1. Provide an overview of DCMF and DCMF involvement/activities for advancing development of CMFs.
    2. Share CMF gap analysis and seek feedback from stakeholders.
    3. Share current CMF research needs.
    4. Share a list of resources and current ongoing activities (highlights for national and international) that may support efforts to advance CMF development and other related efforts.
    5. Identify efforts and resources that may be coordinated or shared by stakeholders.
    6. Identify needs and opportunities for addressing CMF development needs.
    7. Identify short- and long-term efforts that are required to advance CMF research and development.
    8. Get feedback for followup activities.
