Techniques for Analyzing the Effect of Road Geometry on Accident Rates Using Multifactor Studies

The purpose of this paper is to discuss techniques developed in a study undertaken in Queensland to determine the effect of unsignalized intersection geometry on accident rates. This paper discusses four problems identified with using a multi-factor approach and discusses numerous techniques to mitigate these problems. Application of the techniques has resulted in numerous relationships being identified between unsignalized intersection geometry and accident rates. This approach was chosen because numerous studies in the literature review that identified opposite relationships to that expected used a multi-factor approach. This study used a multi-factor approach, which considers simultaneously the effects of many factors on the incidence of accidents. By undertaking a study using this approach, reasons for the previous results could potentially be identified and new techniques developed.
