Abstract: Roundabout controlled traffic intersections have been in recent use in USA, UK and Germany for their special attribute to manage traffic and so there are many software models being made of intersection for analyzing them in heavy traffic condition. Mumbai being the most populated city after Delhi where every resident has either a two wheeler or four wheeler or both vehicles makes it bad for the traffic flow as everyo
ne use their own vehicle and so during peak hours there are severe long traffic jams seen, also new startups like OLA and Uber are bringing more cars on road. As there are Metro constructions going on, there are many traffic jams seen on the intersections of the city of dreams. The Western Express Highway and the Eastern Express Highway being express roads gets to see many jams on the intersections of the service roads and station roads. Long Traffic Jams are seen at the Jogeshwari Vikroli Link Road (JVLR) even after constructing the East West Flyover so as there were severe traffic jams because of the vehicles which travelled from east to west of Jogeshwari. These jams are not only because of number vehicles but also due to Traffic Signals and the traffic management. As the people of this city are always in a hurry not everyone follows the traffic rules and signals, which leads to many accidents and so more traffic jams. Despite of increasing the number of public transport facilities, they do not meet the solution for transporting the citizens. The trains managed by Indian Railways are full during the peak office hours, same can be said about the Bus Services managed by Brihan Mumbai Electric Supply and Transport (BEST). To solve this traffic problem, roundabouts can be implemented on these intersections of the Station Road and the Highway Service Roads which are Signal Controlled, leading to traffic accumulation on each side of the traffic whereas if it is Roundabout controlled there can be a smooth flow of traffic as the roundabouts allow smooth flow of 1800 vehicles per hour as per practical experiment done in Detroit, USA [33]. As on the traffic signals the traffic accumulates on the either side of the signal there are basic and wear and tear happening due to stopping and vehicle collision and also the fuel is being wasted waiting for the signal to turn green. In this paper we shall discuss about the implementation of roundabouts on the intersections and the flow of traffic after the implementation.
