Abstract: Congestion has become a main concern in cities like Mumbai, Bengaluru, Kolkata, and Delhi. Bengaluru City has witnessed a phenomenal growth in vehicle population from 48.69 lakh to 70.28 lakh in last 10 years. In this project an attempt is made to reduce the volume on the road by identifying and assigning traffic volume to underutilized road to decease the delay. The study area is selected from Outer ring road via Hoskeralli junction till Katriguppe circle as main road and 2nd main road via water tank road to Katriguppe circle. The road inventory survey, Traffic volume, delay study was done and to understand driver perception of choosing a particular road, Road side interview was conducted. The driver responses were analyzed and traffic was assigned to second main road by Wardrop’s user equilibrium function. The field data was simulated and calibrated by using VISSIM software. Traffic volume of the Outer Ring Road from Karnataka Power Transmission to Katriguppe via Hoskerehalli junction was observed to be 4324 vehicles / hour. On the 2nd main via water tank road to Katriguppe was observed to be 2609 vehicle/hour. The capacity of both roads was found to be 3284 vehicles/ hour. V/C ratio is 1.32 on outer ring road and 0.79 on 2nd main road. On Outer ring road traffic volume of 3035 vehicles/hour shall be diverted to second main road to reduce travel time by 3 minutes per vehicle. In order to reduce congestion and maintain V/C ratio less than 1, traffic volume of 3808 vehicles/hour and 3035 vehicles/hour shall be assigned on Outer ring road and 2nd main road respectively with travel time of 2 minutes 49 seconds on both the roads by reducing the delay at intersection.
