Summary

The 2006 Louisiana Traffic Records Data Report, prepared by the Louisiana State University Highway Safety Research Group, provides a comprehensive statistical analysis of traffic safety in Louisiana for the year 2006. The report addresses the magnitude, trends, and contributing factors of traffic crashes, aiming to quantify the economic and human costs of motor vehicle incidents. It highlights that traffic fatalities and injuries impose a significant burden on the state, with the primary contributing factors identified as alcohol impairment and low safety belt usage. The study utilizes traffic reports received prior to July 30, 2007, and employs a data mining algorithm developed at LSU to estimate alcohol involvement where testing data was missing, noting potential deviations from Federal Highway Administration records due to methodological differences. The report analyzes data across multiple dimensions, including crash severity, location, time, driver demographics, and vehicle types. It normalizes crash counts using vehicle miles traveled, licensed drivers, and population statistics to determine rates. Key metrics include fatal crashes, injury crashes, property-damage-only crashes, and specific subsets such as pedestrian, bicycle, and motorcycle incidents. The analysis covers geographic distributions by parish and highway type, temporal patterns by month and day of the week, and behavioral factors such as seatbelt use, helmet use, and blood alcohol concentration (BAC) levels. In 2006, Louisiana recorded 889 fatal crashes resulting in 985 fatalities, a 2.1% increase from 2005. The total economic cost of these crashes was estimated at $6.04 billion, or $2,126 per licensed driver. While the number of injury crashes decreased by 1.6% to 48,682, motorcycle fatalities surged by 27% to 94, and interstate fatal crashes increased by 13%. Alcohol was estimated to be involved in 46% of all traffic fatalities and 8.9% of injury crashes. Occupant protection remained a critical issue, with 62% of drivers and passengers aged five and older killed in crashes not wearing safety belts. Additionally, 40% of children under five killed were not properly restrained. Pedestrian fatalities decreased by 8% to 99, accounting for 10.1% of all traffic deaths. The report concludes that despite slight decreases in some injury metrics, the rising fatality rates, particularly among motorcyclists and on interstates, alongside persistent high rates of alcohol involvement and non-compliance with restraint laws, indicate significant ongoing safety challenges in Louisiana.

Key finding

In 2006, 46% of traffic fatalities in Louisiana were estimated to be alcohol-related and 62% of occupants killed were not wearing safety belts.
