Traffic Performance Analysis on the Kedung Baruk Highway Section Surabaya

Abstract

Transportation plays an important role in supporting community mobility, social activities, and economic functions. The rapid growth of population and motor vehicles has increased pressure on road infrastructure, resulting in congestion, decreased service levels, and traffic accidents. Therefore, a comprehensive traffic performance analysis is necessary to determine the extent to which a road segment can effectively accommodate vehicle flow. This study was conducted on Kedung Baruk Main Road in Surabaya, which frequently experiences congestion due to high vehicle volume and side friction factors, such as illegal parking and activities along the road shoulder. The study was conducted through manual daily traffic surveys on April 22, April 25, and April 28, 2024, following the PKJI 2023 guidelines. The analysis results indicate that the highest peak hour occurred on Monday from 17:00 to 18:00, with a volume reaching 1,959.7 passenger car units per hour (pcu/hour) on the 2/2-TT road type. The side friction condition on this road segment is classified as very low (SR) with an occurrence frequency below 100. Meanwhile, the highest degree of saturation (DOS) value was found on the 2/2-TT road type at 0.81, indicating a Level of Service (LOS) D, whereas the 4/2-T road type had a DOS of 0.57 with LOS C. The results of this study indicate that the capacity of Kedung Baruk Main Road is nearing its maximum limit, especially for the 2/2-TT road type. Therefore, more optimal traffic management is required to improve the performance and comfort of road users.
