This paper was presented at Session 31 - Traffic Systems and Analysis 2. Prior to the introduction of a priority road system in South Australia it was decided that a "before and after" type study should be implemented to measure its impact on accident patterns and the total traffic environment. This paper presents a brief summary of the methodology used to make this evaluation and describes some of the changes which have occurred since a priority road system has been introduced in the Adelaide metropolitan area. The main effect of their installation was a significant reduction in right-angle accidents, resulting in an annual saving in accident cost of approximately $193 000 for the four priority roads studied.
