Develop Safety Performance Functions (SPF) for Illinois

Using descriptive and advanced statistical techniques, this study will provide analytical tools for Illinois Department of Transportation (IDOT) to identify and manage a program of site-specific, and systematic improvements to develop strategies to reduce fatalities and severe injuries resulting from motor vehicle crashes. The SPF models developed from this study will be directly used to screen for candidate locations in the Illinois roadway network for safety improvements. The multivariate statistical models will help IDOT to develop comprehensive strategies to reduce motor vehicle crashes.
