Assesmental Study and Redesign of Rotary Intersection

Abstract

The present paper deals with the study on design of rotary intersection at RAMALINGAPURAM junction This study leads to redesign the roundabout or to provide suitable alternative at intersections. The basic principle considered for design includes the principle of uniformity and simplicity, minimize conflict points, alignment and profile.The capacity studies of intersections of Nellore city was calculated based on the established norms of the Indian road congress (IRC: 65-1976). The performance analysis of rotaries is based on various parameters such as traffic volume, weaving traffic, capacity of weaving section. The resulting performance leads to a new model development. The traffic volume survey and geometric design survey is conducted.
