Summary
This study addresses the persistent safety risk of reckless driving on Wisconsin roadways, defined as crashes involving speeding, distracted/drowsy driving, impaired driving, or aggressive driving. Despite advancements in vehicle technology, these behaviors remain significant contributors to crash statistics, accounting for substantial portions of total crashes in the state. The research aimed to enhance the understanding of reckless driving’s role in traffic safety, identify effective engineering-based countermeasures, and develop tools to prioritize high-risk locations for intervention. The methodology comprised three phases: an extensive literature review, stakeholder interviews, and statistical modeling. The literature review synthesized national findings on engineering strategies, evaluating interventions such as dynamic speed feedback signs, rumble strips, high-tension cable barriers, and road diets using crash modification factors (CMFs) and empirical studies. Stakeholder interviews with state Departments of Transportation, insurance companies, and vehicle manufacturers provided insights into practical challenges and innovative solutions, including automated speed enforcement and intelligent speed assistance. For the quantitative analysis, the team utilized Wisconsin crash, roadway, and public health data from 2017 to 2021. Crashes flagged with contributing factors of speeding, distraction, impairment, or aggression were categorized as reckless. Negative Binomial (NB) regression models were developed to estimate crash risks across various roadway segments, accounting for overdispersion in the count data. Key findings indicate that average annual daily traffic (AADT) and segment length are positively associated with crash frequencies for all four types of reckless driving. Roadways with more lanes and wider lane widths were also linked to increased risks for speeding, impaired, and distracted driving crashes, respectively. Conversely, higher posted speed limits and the presence of wider shoulders were consistently associated with reduced crash risks across all reckless driving categories. These predictive models were integrated into a network screening tool designed to identify high-risk locations. The tool enables the Wisconsin Department of Transportation to prioritize segments characterized by high traffic volumes, wide lanes, and multiple through lanes. The significance of this work lies in its provision of a data-driven foundation for resource allocation and targeted safety interventions. The study recommends prioritizing network screening at high-risk segments and implementing specific countermeasures, such as median installations, shoulder widening, and traffic calming treatments, to regulate speed and reduce aggressive maneuvers. By identifying locations most susceptible to reckless driving crashes, the research supports efforts to improve roadway safety and reduce the frequency of crashes associated with these risky behaviors.
Key finding
Higher average annual daily traffic and segment lengths increase reckless driving crash frequencies, whereas wider shoulders and higher posted speed limits are associated with reduced crash risks.
