Abstract

Tourism activities in Gianyar Regency are heavily concentrated in the areas of Ubud, Tegallalang, and Payangan (ULAPAN), resulting in high traffic volumes that cause significant congestion on various roads and intersections leading to and within these areas. This study aims to evaluate the performance of seven road sections and five intersections, as well as to explore traffic management strategies in the ULAPAN area. A quantitative research method was employed, including traffic and geometric surveys on the selected road sections and inter-sections, performance analysis, and side friction analysis based on the 2023 Indonesian Highway Capacity Manual (IHCM). The performance evaluation results indicate that the saturation level of the road sections and intersections exceeds 0.85. This situation could heighten the potential for conflicts between pedestrians and vehicles, compromising tourist safety and comfort. Implementing one-way traffic management and adjusting traffic light timing has successfully reduced the saturation level to 0.38. The proposed traffic engineering management model aims to distribute traffic more evenly across the existing road network.
