Summary
This study investigates the impact of rapid energy sector growth on transportation safety perceptions and crash trends in the seventeen-county oil region of western North Dakota. Motivated by a sharp increase in travel volumes, a shift in traffic composition toward heavy industrial vehicles, and rising crash rates, the research aims to examine public perceptions of safety, analyze crash data from 2004 to 2013, and evaluate the efficacy of public safety campaigns. The region, defined by Bakken and Three Forks oil formations, has seen active wells increase from 3,339 in 2004 to over 10,000 by 2014, placing significant strain on road infrastructure not designed for such heavy loads. The methodology combines longitudinal survey data with county-level crash statistics. Survey questionnaires were administered to drivers in 2012 and 2014 to assess perceptions of danger, driver behaviors, and responses to safety initiatives such as "ProgressZone" and "Code for the Road." Concurrently, the authors analyzed crash data for the entire state, with specific focus on the four central core oil counties (McKenzie, Mountrail, Dunn, and Williams) compared to other areas. The study also reviewed literature on driver behavior, large truck-passenger vehicle interactions, and perceived risk to contextualize the findings. Results indicate that drivers perceive the region as dangerous, particularly regarding interactions with large trucks. Survey respondents reported fear during truck-passenger vehicle interactions and expressed a willingness to alter their routes to avoid roads with heavy truck traffic or poor surface conditions. Crash data reveal that overall crash events in the central core counties grew at near-exponential rates between 2004 and 2013. Specifically, large truck crashes in these counties increased by 1,784%, rising from 38 incidents in 2004 to 716 in 2013. This growth outpaced the increase in vehicle miles traveled (VMT). Fatalities and injury crashes were also significantly higher in the oil region compared to the rest of the state. The study found that while safety campaigns increased awareness, the fundamental danger stemmed from the volume of overweight vehicles and deteriorating road conditions caused by oil extraction activities. The significance of this research lies in its documentation of the severe safety risks associated with rapid industrial expansion in rural areas. The findings highlight that the influx of heavy-duty trucks and the resulting infrastructure degradation have created a hazardous driving environment that exceeds the capabilities of existing roadways. The study underscores the need for targeted intervention strategies, including improved road maintenance, enhanced enforcement, and continued public education, to mitigate the disproportionate crash rates in the oil region. It provides empirical evidence that economic booms driven by energy extraction can have profound negative impacts on transportation safety if infrastructure and traffic management do not keep pace with industrial growth.
Key finding
Large truck crashes in the central core oil counties increased by 1,784% from 2004 to 2013, while drivers perceived the region as increasingly dangerous due to heavy truck traffic and deteriorating road conditions.
