Summary
This document, titled "Illinois Crash Facts and Statistics, 1999" but containing data for the year 2000, serves as a comprehensive statistical report compiled by the Illinois Department of Transportation’s Division of Traffic Safety. The publication aims to provide researchers, media, and safety advocates with detailed data on motor vehicle crash involvement in Illinois to support efforts in reducing traffic deaths and injuries through education and enforcement. The report aggregates data from law enforcement agencies, coroners, and the Medical Examiner of Cook County to analyze crash severity, demographics, environmental conditions, and economic impacts. The methodology involves analyzing reported crashes on public roadways within Illinois, categorized by severity (fatal, injury, property damage), vehicle type, driver age, and roadway conditions. The dataset covers 460,172 total crashes in 2000, resulting in 1,418 fatalities and 134,256 injuries. The report also incorporates historical data from 1981 to 2000 to track trends in fatalities and vehicle miles traveled. Specific subsections detail crashes involving pedestrians, pedalcyclists, motorcycles, school buses, tractor-trailers, work zones, and deer, as well as county-level statistics. Key findings indicate that while travel increased by 0.7 percent, the mileage death rate decreased by 3.3 percent compared to 1999. The total estimated economic cost of crashes was $8.5 billion. Urban roadways accounted for 62.0 percent of fatal crashes and 88.1 percent of total crashes. Alcohol was a significant factor, with 42.9 percent of fatally injured drivers who were tested having a positive Blood Alcohol Concentration (BAC); this rate rose to 45.7 percent for drivers aged 15–24. Rear-end collisions caused the highest number of injuries (29.0 percent), while collisions with fixed objects caused the most fatalities (27.0 percent). Motorcycle fatalities increased by 22.3 percent, and work zone fatal crashes more than doubled compared to the previous year. Conversely, school bus safety remained high, with no school-age passengers killed. The significance of this report lies in its role as a foundational resource for highway safety policy and public awareness in Illinois. By highlighting specific risk factors—such as the high prevalence of alcohol in fatal crashes among young drivers, the disproportionate impact of urban roadways on crash volume, and the rising trend in motorcycle fatalities—the data supports targeted interventions. The inclusion of economic costs underscores the financial burden of crashes, reinforcing the necessity of continued enforcement of seat belt, child restraint, and DUI laws. The report provides a granular view of traffic safety, enabling stakeholders to identify vulnerable populations and high-risk environments to mitigate future crash involvement.
Key finding
There were 1,418 fatalities and 134,256 injuries in 460,172 crashes in Illinois during 2000, with a mileage death rate of 1.4 per hundred million vehicle miles traveled.
