The Federal Highway Administration (FHWA) established the Development of Crash Modification Factors (DCMF) program 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 ultimate goal of the DCMF program is to save lives by identifying new […]
Report No.: DOT HS 812 184 The Model Minimum Uniform Crash Criteria (MMUCC) Guideline, Fourth Edition (2012), is a voluntary guideline designed to help States determine what crash data to collect on their police accident reports (PARs) and what data to code and carry in their crash databases. The MMUCC Guideline does not provide States […]
Report No.DOT HS 812 183 NHTSA publishes crash statistics based on police accident reports, but many crashes are never reported by the police. In 1981 NHTSA sponsored a telephone survey to estimate the incidence of unreported crashes. That survey estimated 47 percent of crashes go unreported. In 2008 NHTSA paid for an updated survey, reported […]
FHWA Publication No.: FHWA-HRT-14-065 The intent of this study was to isolate the effects of various low-cost pavement treatments on roadway safety. This was a retrospective study of pavement safety performance, looking back at crash data before and after treatments were installed. Both flexible and rigid pavement treatments were analyzed, with the majority typically used […]
Report No: SWUTC/15/600451-00077-1 Safety at intersections is of significant interest to transportation professionals due to the large number of possible conflicts that occur at those locations. In particular, rural intersections have been recognized as one of the most hazardous locations on roads. However, most models of crash frequency at rural intersections, and road segments in […]
DOT HS 812 128 The National Highway Traffic Safety Administration’s traffic crash data provides the underpinning for informed highway safety decision-making at the Federal, State, and local levels. Accurate, accessible, timely, and standardized data allows decision-makers to: determine the primary factors related to the sources of crashes and their outcomes develop and evaluate effective safety […]
Report Number: ST-2015-027 FHWA established a data-driven, risk-based approach to oversee States’ compliance with the NBIS, which its Division Offices have effectively implemented. However, we identified gaps in three areas of FHWA guidance that could limit the program’s long-term success. First, FHWA established the Assessment Reporting Tool (ART) to serve as a central repository of […]

Trucking Safely Through Work Zones
Report Number: WBS: 25-1121-0003-140 The majority of crash fatalities in the United States occur along rural roadways. These roadways typically have low volumes and widespread crashes. In other words, no one location generally has an unexpectedly high number of crashes. Systemic safety tools/methodologies can be used in this type of situation because they evaluate and […]
