Systematic Identification of High Crash Locations (HCL)
An Iowa Highway Research Board Project
The proposed research project seeks to develop a tool and a process by which Iowa engineers can identify potentially hazardous roadway locations and designs. By identifying design features or characteristics that may lead to higher crash risk, engineers can proactively avoid such hazards in future roadway designs or eliminate them in existing roadways. Through a series of case studies, the project will identify the relationship between crash rates and specific roadway design features, geometry, or other characteristics (e.g., high levels of truck traffic). The proposed process will be developed based on a system of integrated, geographically referenced databases, whereby the safety performance of Iowa's highways, highway segments, specific design features, and individual locations can be monitored.
