Abstract

Jatingaleh Underpass is designed to solve congestion problem and reduce the rates at which accidents occur at intersections due to conflicts, but bottleneck can affect traffic performance. This study aims to determine in traffic movements, traffic performance after the existence of Underpass based on MKJI 1997, analyze density with the Greenshield linear approach, and analyze the effect of bottleneck. To be more effective, the survey is conducted by using drones. Based on the analysis, the road performance becomes better, but some segments should be optimized because degree of saturation (DS) > 0.75. The vehicle speed results are 52.29; 55.49; 29.87; 26.28 km/hour in segment A; B; C; D and Segment Density C; D = 155.71; 152.86 pcu/km. Vehicle speed on bottleneck Segment C and D, in Setia Budi Street does not achieve the Primary Arterial Road criteria at 60 km/hour with very high density result. Bottleneck causes increased density, raises new conflict points (weaving), decreases vehicle speed up to 42-46%, and causes queue length of 0,150 km. We propose that the Underpass it must be in accordance with the geometric requirements of MKJI, there should be no narrowing of the road in any segment.
