Title: Systematic Approach of Determining State-Wide High Crash Locations Case Study: State of Illinois
Abstract: The Federal Highway Administration (FHWA) encourages states to focus on problems that relate to serve crashes. Section 1401 of the Safe Accountable Flexible Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) amended Section 148 of Title 23 USC to create a new Highway Safety Improvement Program (HSIP) as a core FHWA program with separate funding. The purpose of HSIP is to reduce fatalities and serious injuries on public roads. As part of the new HSIP, States are required to submit an annual report to the FHWA describing not less than 5 percent of their highway locations exhibiting the most pressing safety needs. The intent of identifying these locations is to gain an understanding of the nature and extent of safety problems, provide guidance to the States as to where safety investments are needed, and to provide a basis for tracking the progress toward improving safety in each state. The report also encourages States to make data driven decisions on safety needs by looking at their crash history over time and implementing strategies to better track progress of their roadway system. This paper describes the methodology developed for Illinois that uses available gross data to efficiently target statistically abnormal high crash locations throughout the State where there is a high likelihood that significant improvements to safety can be achieved.
