Designing and implementing effective traffic safety policies requires data-driven analysis of traffic collisions. To help in the policy-making process, the Center for Criminal Justice Research (CCJR) collaborates with the Indiana Criminal Justice Institute (ICJI) to analyze data from the Automated Reporting Information Exchange System (ARIES) database maintained by the Indiana State Police. Each year, CCJR summarizes research findings in a series of publications focused on various aspects of traffic collisions, including alcohol-related crashes, children, motorcycles, light trucks, large trucks, dangerous driving, occupant protection, and young drivers. Portions of the content in these publications are based on guidelines provided by the U.S. National Highway Traffic Safety Administration (NHTSA).
Indiana Crash Facts 2009 provides a detailed summary of 2009 traffic collision statistics and trends. This book, along with a series of annual traffic fact sheets on select topics, is used to inform the public, as well as state and national policymakers, on matters of road safety and serves as the analytical foundation of traffic safety program planning and design in Indiana.
