Capacity Analysis of Un-signalized Intersection: A Case Study of City Junction

Abstract

Traffic flow on National Highway is obstructed by cross traffic from minor roads causing conflicts to vehicular and pedestrian flow. This leads to congestion, delay, accidents, increase in Vehicle Operating cost and decrease in capacity of the intersection. The present study is on intersection between Bangalore Mysore section of NH- and city. The existing T-junction subjecting to more conflicts because of heavy traffic flow on main road and more percentage of Multi Axle Trucks from Minor Road. Traffic volume survey was conducted for peak hours and same data has been analyzed in order to study various alternatives. Based on existing condition and topographical features suitable proposal like Interchange, Grade Separator, Roundabout and Ramps have been studied to propose best solution.
