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 annually 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 driver history, alcohol-related crashes, child passenger safety, motorcycles, 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 2011 provides a comprehensive summary of 2011 traffic collision statistics and trends, including a section on problem identification related to goals defined in the Indiana Strategic Highway Safety Plan, and a set of detailed analyses of individuals and vehicles involved in collisions, and collision characteristics and contributing circumstances such as alcohol-involvement, speeding, work zones, and motorcycles. The book concludes with a section devoted to county-level analyses that includes a number of maps illustrating county data by these same variables.
