As part of its ongoing effort to reduce highway crashes in Indiana, the Indiana Department of Transportation (INDOT) has updated and improved its program to identify and evaluate areas in the state’s highway network with higher than average crash rates.
Each year Indiana produces a Five Percent Report. The Five Percent (5%) Report is required under SAFTEA-LU to insure that the states are transparent in revealing their traffic safety needs on both the state controlled and local public road systems. As such the contents of the 5% Report are posted on the federal web site and by federal law are immunized against use in tort litigation. The Office of Traffic Safety uses the annual Five Percent Report to identify previously unknown sites with safety issues for investigation and possible project programming.
The locations listed on each report account for more than five percent of all Indiana fatality or serious injury crashes in the previous three years prior to the report year. To rank the locations for the report, analysts looked at a number of factors including crash frequency, rate and severity.
As a result of each five percent report, safety experts have or will conduct onsite safety reviews across the state. INDOT then programs projects at the locations where engineers conducting the reviews identified feasible infrastructure projects to improve safety.
Indiana’s Five Percent Report allows INDOT to identify potential solutions to roadway concerns and direct highway funding to the areas where it is most needed. INDOT has already scheduled improvements for many of the locations listed on previous reports. Those locations not currently scheduled for remediation undergo a safety evaluation by a team of INDOT engineers. These teams will identify possible solutions to correct any roadway deficiencies using the four E’s: engineering, education, emergency response and enforcement.
INDOT is committed to reducing crashes on Indiana’s roadways, and Indiana’s Five Percent Report is just one of several ways INDOT selects locations to receive safety reviews and programs safety projects. Other methods used to seek out candidate locations include recommendations by Indiana’s Metropolitan Planning Organizations (MPO), local transportation agencies and other highway safety partners. INDOT also analyzes statewide crash trends to locate sites where specific safety measures would be effective.
Five Percent reports are included below for 2010 through 2012.
