Abstract: Unsignalized intersections are the key elements in urban streets and in rural road networks. The methodology for the analysis of unsignalized intersections has been established where homogeneous traffic conditions are dominated, there are several attempts made to develop different approaches for the analysis of unsignalized intersections under mixed traffic conditions. Conflict technique is a recent development, which is based on pragmatically simplified concept, considering interaction and impact between flows at intersection. In present study, capacity of unsignalized intersection was calculated from Conflict technique. Surveys were conducted in Visakhapatnam, to measure different traffic parameters such as volume, flow $ capacity to this method. Movements of capacity were evaluated by HCM (2000) by comparison with approach wise capacities obtained from conflict technique.
