With the continuous increase in the urban population, the number of vehicles is also increasing rapidly, as a result of which the traffic situation is inevitably deteriorating. This deteriorating traffic condition results in wasted countless hours of commuters. Mitigating traffic congestion is no less than a challenge for the betterment of a nation's socio-economic system and society. Therefore, this study proposes a GA based framework to optimize the green phase times for the traffic signals that can minimize the average vehicle delay for the signalized roundabout, specifically for the peak hours. Based on the actual traffic flow data, a microsimulation model of a roundabout is also developed for the evaluation with the help of PTV VISSIM (a microsimulation tool). First GA model will search for the appropriate green phase timing for different cycle lengths and then the microsimulation model will be used for the evaluation of results. It is concluded that the optimized green phase timing can effectively reduce average vehicle and stop delays, and will also help in improving the traffic capacity of that signalized roundabout.
