The Effect of Divergent Flow on U-Turn on Traffic Flow Performance (Case Study of A. Yani Road Km. 35 Banjarbaru)

Dewi Shafitri Arifanti, Iphan Fitrian Radam

Abstract


The divergent flow generated on the u-turn when the vehicle makes a u-turn movement can affect traffic performance, especially during peak hours. This problem also occurs on the u-turn of A. Yani Road Km. 35 Banjarbaru. Therefore, it is necessary to conduct research to find out the extent of the influence that divergent flows have on traffic performance. The research was conducted on conditions that were affected by u-turn and which were not affected by u-turn . From the analysis results, the selected model when the u-turn operates normally is the Underwood model with the results of Sm = 16,707 km/hour and FC = 1392.209 pcu/hour. While the selected model when the u-turn is closed is the Greenshields model with the results of Sm = 26,383 km/hour and FC = 4576,975 pcu/hour. When affected by u-turn, Sm value decreased by 36.68% and FC value decreased by 69.58%.
