LITERATURE REVIEW ON COMPARISON OF CAPACITY MODELS OF ROTARY INTERSECTION

Abstract

 Tanner Model of Capacity and IRC model of Capacity are two different traffic analysis model in terms of
capacity that are capable of modeling urban roads with rotaries. This study compares the performance of the two
different methods in modeling dual lane rotaries under different scenarios such as traffic volume, proportion of left
turning movement, and proportion of trucks in the traffic flow. However; in the case of high traffic volumes, Tanner
Model showed higher average delays compared to nearly identical results in the case of low traffic volumes. The present
traffic scenario is usually used to characterize the present traffic condition to access the different parameters at different
types of intersection.
