Abstract

The roundabout capacity analysis method used in aaSIDRA was originally based on the method described in ARRB Special Report SR 45 (Troutbeck 1989) which was introduced into aaSIDRA with some variations and extensions (Akcelik and Troutbeck 1991 ). The SR 45 method was also incorporated into the Austroads (1993) Roundabout Guide with some minor modifications (Troutbeck 1992). Subsequently, significant enhancements were introduced in various versions of aaSIDRA, including some important changes introduced in the latest version aaSIDRA 2.1, based on further research and development (Akcelik & Associates 2004; Akcelik 2003a, 2003b, 2004; Akcelik, Chung and Besley 1997, 1998). This paper presents a summary of the differences between the AUSTROADS Roundabout Guide and aaSIDRA methods for roundabout capacity and performance analysis, and discusses some important aspects of the analysis method where significant differences exist.
