Join transportation engineers, designers, and planners from across the country in this webinar to learn about recent updates to the Federal Highway Administration (FHWA) Crash Modification Factors (CMF) Clearinghouse, CMFs for bicycle treatments at intersections, and the safety effectiveness of Rectangular Rapid Flashing Beacons (RRFB) pedestrian enhancement.
Presenters:
Sarah Weissman Pascual, FHWA, and Raghavan Srinivasan, with the University of North Carolina Highway Safety Research Center and manager of the CMF Clearinghouse, will provide an overview of the CMF Clearinghouse and the resources available for assistance.
Raul Avelar, Senior Research Transportation Engineer, Insurance Institute for Highway Safety, will discuss research investigating the development of CMFs for bicycle treatments at intersections.
Amrita Goswamy, ITS Engineer at AECOM, will share insight from recent work exploring the safety effectiveness of RRFB pedestrian enhancement.
Continuing education: Attendees will be eligible to receive a certificate of completion for 1.5 hours that can be applied toward Professional Development Hours (PDH) credit, per State requirements.
We’ve moved! ICYMI: The CMF Clearinghouse website officially changed from *.org to *fhwa.dot.gov in August 2024. This change has no impact on CMF Clearinghouse users and automatic redirects are in place until September 30, 2025, to help you get to where you need to be from old links.
Going forward, please update your saved addresses to https://cmfclearinghouse.fhwa.dot.gov for “a searchable database of CMFs along with guidance and resources on using CMFs in road safety practice.”
Questions regarding the domain change? Contact Sarah Weissman Pascual (sarah.pascual@dot.gov) or Raghavan Srinivasan (srini@hsrc.unc.edu).
Improved Filter Functionality
With more than 8,700 CMFs, the CMF Clearinghouse is a powerful tool, but sometimes it's tricky to find exactly what you're looking for quickly. The CMF Clearinghouse team has made further improvements to the overall search feature and functionality of the database to dynamically narrow search results as you search for a CMF, allowing users to better refine their search criteria based on the returned results. Visit https://cmfclearinghouse.fhwa.dot.gov, and see what you think!
Got State Selected CMFs?
Twenty-two states have developed their own internal state CMF lists so that there is consistency in CMF use across their states. Sharing this information is helpful for other states who are considering developing their own state CMF list, too.
Safe System Project-Based Alignment Framework and Tool
Thinking about transportation safety more broadly, FHWA has published a valuable new resource for practitioners, the Safe System Project-Based Alignment Framework (FHWA-SA-2023-009). This framework can be used to assess locations and potential improvements through a Safe System Approach (SSA) lens and provides practitioners a means for contrasting roadway safety improvements relative to one another through a scoring matrix, which focuses on Exposure, Likelihood, and Severity of both vulnerable road users and motor vehicle occupants.
A tool to implement this framework is available as an excel spreadsheet (https://highways.dot.gov/sites/fhwa.dot.gov/files/2024-04/PR1_FHWA_LcLRrlRds_ProjFrmwk_Apr24%20FINAL_0.xlsx). It provides comparative analysis based on a series of data inputs and risk evaluations. It uses inputs and information typically available at the project planning stage, available via online mapping or roadway inventory database systems, or by field review of a given location.
Call for Data for Evaluations of Low-Cost Safety Improvements-Pooled Fund Study
FHWA is starting to develop CMFs for curb extensions, narrow width rumble strips, and wide width pavement markings as part of The Evaluations of Low-Cost Safety Improvements-Pooled Fund Study.
If representatives from any agencies have information regarding sites that have these countermeasures or will have them in the near future and have data you can share, please contact: Woon Kim, FHWA Safety Data and Analysis Team, woon.kim@dot.gov or 202-493-3383.
The CMF Clearinghouse welcomes CMF study submissions to be included in its searchable database. If you wish to submit your CMF study, please email Sarah Weissman Pascual at sarah.pascual@dot.gov. Be sure to search the Clearinghouse before submitting a new CMF as we may already have it listed. You may either send a link to a resource already existing on the web (preferred) or include it as an attachment in the email. Submissions might include published research studies that are not presented in the Clearinghouse, or state-specific CMFs that were developed as part of the Highway Safety Improvement Program. Please note that the Clearinghouse only includes CMFs that are derived and presented in the studies by the authors.
