Investigation of Commercial Motor Vehicle (CMV)-Related Crashes in Ohio Work Zones

As part of a larger Commercial Motor Vehicle (CMV)-related analysis, Federal Highway Administration (FHWA) and their researchers, have analyzed National Highway Traffic Safety Administration's (NHTSA's) Fatality Analysis Reporting System (FARS) data from 2012 to 2017 and found that approximately 10 states (including Ohio) accounted for over 60 percent of the CMV fatal crashes in work zones nationally. This has led to these 10 states being targeted as opportunity states. FHWA is leading targeted state-level workshops within the opportunity states to develop state-specific action plans. Ohio's state specific action plan, which was finalized in April 2021, includes many different strategies and action items; however, did not get to the level of determining crash causation for CMV-related crashes in Ohio's work zones to either confirm or rule out the strategies being proposed. When comparing Ohio's crash statistics, the number of Strategic Highway Safety Plan (SHSP) Emphasis Area CMV-Involved crashes is lower in work zones as compared to statewide (Figure 1); however, when comparing the respective percentages there is an overrepresentation of CMV-Involved crashes in work zones as compared to statewide. While potential contributing factors to CMV-related crashes in Ohio's work zones can be multifaceted and/or transitory (such as speed differentials induced by construction vehicles using construction access points), it has remained difficult to identify any statistically significant crash causation trends and factors for this category in order to best target limited resources towards reducing these crashes. Research is needed to further our efforts in this area. The goal of this research is to improve the safe movement of CMVs in Ohio's work zones. The objectives of this research include the following: (1) Obtain/Collect and analyze data to confirm or rule out if construction access points (as designed and/or as implemented) are adversely impacting CMV-related crashes in Ohio's work zones. (2) Obtain/Collect and analyze data to identify any other CMV-related crash causation trends or factors adversely impacting CMV-related crashes in Ohio's work zones. (3) Develop recommendations for how to target resources to best address the underlying causes of CMV-related crashes in Ohio's work zones using one or more of the following: engineering design/standards, enforcement and/or education.
