Data is the foundation of every highway safety program. Knowing how, when, where, and why traffic crashes occur and who is involved gives engineers and other safety advocates clues to the types of strategies that can prevent crashes and reduce their severity.
In Ohio, crash reports are filed by more than 1,000 law enforcement agencies, then collected and analyzed by the Ohio Department of Public Safety. ODOT also analyzes the crash data, combining it with roadway and traffic volume information to identify locations and safety improvements with the greatest potential for reducing crashes. In addition, ODOT has developed user-friendly tools that automate the analysis so people at various skill levels can use the information to make better safety investments.
Below is a list of the most commonly used tools and links to more information.
