VALIDATION OF THE CAPACITY ESTIMATION MODEL FOR URBAN THREE-LANE TRAFFIC CIRCLES

Abstract

Currently, three-lane traffic circles are widely used in cities of the Russian Federation. At the same time there are no methods for calculation of the capacity of such traffic circles, taking into account the peculiarities of traffic modes in urban conditions. The paper presents substantiation of development of a model for estimation of capacity of multilane roundabouts based on the conflict points. The development of such a model will allow to carry out a comparative analysis of the efficiency of multilane roundabouts with signalized roundabouts and turbo-roundabouts.
