Summary

This report, produced by the Alaska Department of Transportation and Public Facilities in cooperation with the Federal Highway Administration, analyzes traffic collision data for the year 2002. The document addresses the scope, severity, and contributing factors of traffic accidents in Alaska, providing a statistical overview to inform transportation safety policies. It highlights a 12.5% decrease in processed crash reports compared to the previous year, noting that difficulties in distributing new reporting forms may have led to underreporting of property-damage-only and minor injury collisions. Despite fewer reports, data from 1993 to 2002 suggests a trend of increasing severity among reported collisions. The study relies on police and driver-reported crash data, with police agencies filing reports for 90.1% of the 13,325 collisions recorded. The analysis categorizes crashes by injury severity, vehicle type, location, and contributing factors such as alcohol and speed. Key metrics include crash rates per 100 million vehicle miles traveled (VMT) and demographic breakdowns of occupants. The report also examines temporal distributions (month, day, time) and geographic distributions across Alaska’s maintenance regions and boroughs, with specific attention to the Municipality of Anchorage and the National Highway System. In 2002, traffic collisions injured 6,370 Alaskans and killed 89. There were 272 collisions and 1.82 fatal crashes per 100 million VMT. Property damage only accounted for 67.5% of crashes, while 27.8% involved non-incapacitating injuries and 4.1% involved incapacitating injuries. Alcohol was a factor in 8.5% of all crashes and 41% of fatal crashes, with the alcohol-related fatality rate standing at 38.2%. Speed contributed to 21.1% of all crashes and 35.9% of fatal crashes; notably, 29% of alcohol-related crashes also involved unsafe speed. Seventy-six percent of all collisions occurred on urban roadways, though fatal crashes were more evenly split between urban (56.4%) and rural (43.6%) locations. The Municipality of Anchorage accounted for 64.4% of all collisions and 41% of fatal crashes. The findings underscore the critical role of alcohol and speed in severe crashes, particularly fatalities. Safety equipment usage varied by vehicle type: 77.8% of automobile, truck, and bus occupants wore seatbelts or used child restraints, while only 52.9% of motorcycle occupants wore helmets. Pedestrians and bicyclists were involved in 191 and 204 collisions respectively, with 17 pedestrian fatalities and no bicyclist fatalities. The report concludes that while total reported collisions decreased, the proportion of severe incidents appears to be rising, potentially due to reporting biases. The data provides a baseline for evaluating the effectiveness of safety interventions and identifying high-risk areas and behaviors, such as the high concentration of crashes in Anchorage and the significant overlap between alcohol impairment and speeding in fatal incidents.

Key finding

Alcohol was involved in 41% of fatal crashes and speeding contributed to 35.9% of fatal crashes in Alaska during 2002.
