Summary

This report, titled *Indiana Crash Facts: 2010*, presents a comprehensive statistical analysis of traffic collisions in Indiana to inform policy-making and safety program design. Produced by the Indiana University Public Policy Institute’s Center for Criminal Justice Research in collaboration with the Indiana Criminal Justice Institute, the document utilizes data from the Automated Reporting Information Exchange System (ARIES) maintained by the Indiana State Police. The study aims to assess the state of traffic safety against benchmarks established in Indiana’s Highway Safety Plan, focusing on priority areas such as alcohol involvement, speed, young drivers, and non-motorist safety. The methodology involves analyzing over 200 data items per collision from the Indiana Officer’s Standard Crash Report, covering details such as time, location, vehicle types, driver conditions, and collision circumstances. The report aggregates this data to calculate rates per 100 million vehicle miles traveled (VMT), per 10,000 licensed drivers, and per 100,000 population, allowing for comparisons across years, counties, and demographic groups. It also incorporates economic cost estimates and observed safety equipment usage rates. Key findings for 2010 indicate a 1.7 percent increase in total collisions (192,890) and an 11 percent increase in fatal collisions (701), resulting in 754 fatalities. Speed-related collisions accounted for 9.6 percent of all crashes and 19.4 percent of fatal crashes, while alcohol-related collisions comprised 4.3 percent of all crashes and 24.7 percent of fatal crashes. The 16-to-17-year-old age group exhibited the highest crash rate among drivers (982 per 10,000 licensed drivers). December recorded the highest collision frequency. Among non-motorists, 76 were killed, including 62 pedestrians. Only 46.5 percent of persons killed in motor vehicle collisions were known to be restrained. The total economic cost of these collisions exceeded $4.4 billion. The significance of this report lies in its role as a foundational tool for traffic safety planning in Indiana. By identifying specific trends—such as the rise in fatalities and the disproportionate impact of speed and alcohol on severe outcomes—the data supports targeted interventions. The findings highlight the need for continued focus on restraint usage, speed management, and impaired driving enforcement. The report serves state and national policymakers by providing evidence-based metrics to evaluate the effectiveness of current safety programs and to set performance goals for future fiscal years.

Key finding

Indiana recorded 754 traffic fatalities in 2010, with 24.7 percent of these fatal collisions involving an alcohol-impaired driver and 19.4 percent being speed-related.
