Evaluation and Reconfiguration of Multifarious Traffic at Rotary Intersection

Abstract

With the advancement in transportation and urbanisation, traffic congestion has become the main socioeconomic problem in urban as well as rural areas in developing countries. Traffic congestion is managed conventionally
by signalisation, widening the roads, interchanges and intersections. Intersections provided sometimes proves the best
but growth of population leading to continuous increase in traffic brings with it a deadlock condition. It is necessary to
design the intersection that present as few impediments to efficient travel as possible and thereby making a number of
countermeasures to be implemented to lessen the adverse effects of intersection hazards. This study deals with Rotary
Intersection (Roundabouts) connecting National Highway-147 (Himmatnagar-Ahmedabad) and Gandhinagar -
Dahegam road. Multi- modal traffic augments the congestion at this intersection. The study works for three main
parameters: Capacity of Rotary Intersection, Heterogeneous traffic flow and suitable measures to be taken for reducing
Traffic congestion and reconfigure the intersection. The framework will comprise of collection of accident data
,measurements of geometric elements and its comparison with the standards of IRC: 65-1976 guidelines, also the public
survey to have the idea of prevailing conditions. Further setting forth possible alternatives and come up with best
gratifying solution which will analyse and optimise the traffic flow.
