This project report identifies the high crash locations on the Interstate, US, and State highway systems in the state of Arkansas. High crash locations can be defined as any highway location which has a higher frequency of crashes compared to other roadway locations due to local factors including factors such as driver behavior, traffic, geometric and control conditions, etc. There are eight Interstate, nineteen US, and two hundred and thirty nine State highways in Arkansas and all were considered in identifying the high crash locations. Literature review was conducted on the different methods and based on the literature review three methods were selected for the identification and ranking of high crash locations. Three year crash data, 2004 to 2006 was analyzed and the Empirical Bayes, Crash Rate, and Equivalent Property Damage. Only methods were selected to identify the high crash locations. These methods were found to be apt as they involved parameters like the Annual Average Daily Traffic, crash frequency and severity. The Empirical Bayes method was found to be advantageous as it takes into consideration the effects of random variation in events. The Equivalent Property Damage Only method was useful as it weighted the different characteristics of a crash.
