Summary
This report presents the findings of Phase I of the Statewide Traffic Safety Study of Louisiana, conducted by the Louisiana Transportation Research Center and sponsored by the Louisiana Department of Transportation and Development. The study was motivated by Louisiana’s persistently poor traffic safety record, characterized by crash rates consistently ranking among the ten highest in the nation, high incidences of alcohol-related accidents, and rapidly increasing auto insurance costs. The primary objective was to synthesize the current state of the art in highway traffic safety to establish a foundation for subsequent research phases aimed at identifying specific contributing factors and recommending countermeasures. The methodology involved a comprehensive literature review of traffic safety research, practices, and analytical procedures both within the United States and internationally. The authors examined crash-related contributing factors across three domains: human factors (including age, alcohol and drug impairment, aggressive driving, and driver inattention), roadway environment factors (such as design, roadside hazards, and conditions), and vehicle factors (covering light and heavy vehicles, motorcycles, and equipment failures). Additionally, the report reviewed the impact of Intelligent Transportation Systems (ITS) on safety. The study also conducted an inventory of existing safety legislation at federal and state levels, analyzed various safety enforcement programs (including automated enforcement, cell phone bans, and occupant protection initiatives), and assessed available analytical tools and software packages like the Highway Safety Manual and SafetyAnalyst. Finally, the authors reviewed safety-related funding trends and compiled a list of federal and Louisiana crash-related databases. The review confirmed that road safety is a critical issue in Louisiana, with a fatality rate significantly higher than the national average. The literature synthesis highlighted that crashes are rarely caused by a single factor but rather by a combination of human, environmental, and vehicle elements. The report detailed the prevalence of specific issues such as speeding, red-light running, and impaired driving, while also noting the potential benefits of emerging technologies and enforcement strategies observed in other states. The inventory of databases identified key resources, including the Fatality Analysis Reporting System and Louisiana-specific crash data, which are essential for the next phase of the study. The significance of this report lies in its role as a foundational document for a broader research program. By providing a comprehensive overview of existing knowledge, legislation, and data resources, the study enables the design of a targeted research program for Phase II. This subsequent phase aims to establish a dedicated database of Louisiana road safety information, analyze the data to draw specific conclusions about local traffic safety conditions, and identify actionable courses to improve road safety. The report thus serves as a critical bridge between general traffic safety knowledge and the specific, data-driven interventions required to reduce Louisiana’s high crash rates and associated economic burdens.
Key finding
Louisiana's crash rate is consistently among the ten highest in the nation, alcohol-related accidents are among the highest in the country, and car insurance rates have grown more rapidly than in any other state.
