Abstract
Identifying and classifying intersections according to severity is very important for effective implementation of safety related counter measures and ‘base crash rates’ are needed to compare and assess the severity. This research is aimed at developing the base or expected crash rates for intersections considering intersection approach as the unit of analysis for different types of controls on a leg by leg basis. Intersection related data from ODOT, coupled with data collected from photologs, identified left turn crashes, population densities were used for developing models. The database was spilt into 2/3 and 1/3 for building models and validating respectively. AID technique was used to separate the data into exclusive groups, and multiple regression was used to further reduce variance. The models developed can be used to calculate base crash rates which can be used for determining if the crash experience at a study site is abnormal.
