Abstract

This paper focuses on the Highway Capacity Manual (HCM) and Australian methodologies for signalized intersections, describes similarities and some significant differences, as well as the SIDRA software which has eliminated the use of opposed turn adjustment factors for lane groups and adopted an explicit and direct method of modeling individual lanes. The discussion is relevant to opposed turn modeling in general and will be useful towards explaining the HCM option in the SIDRA program. The limitations of the HCM model are pointed out.
