摘要：	The main goal of this research project was to evaluate the current Iowa Department of Transportation (Iowa DOT) safety improvement candidate list (SICL) process. A survey of 17 other state departments of transportation was conducted to determine the state of the practice in other areas. The first objective of the research was to evaluate whether fatalities overwhelm the current Iowa DOT SICL process. The second objective was to perform a sensitivity analysis to evaluate impact of the individual ranking methods (Crash Frequency, Crash Rate, and Value Loss) on the final ranking, which results in the final safety improvement candidate list. The final stage of this research was a workshop that was held on June 7, 2002, at the Center for Transportation Research and education. Workshop participants discussed alternative ways to rank high crash locations.
