Evaluasi Kinerja Simpang Empat Tak Bersinyal (Jl. Raya Kepuharjo – Jl. Balai Desa Kepuharjo – Jl. Pertamanan) Karangploso Malang

Abstract

Roads are vital land transportation infrastructure that support human life. One of the key components of roads is intersections. Intersections are critical elements in the transportation network as they play a crucial role in regulating traffic flow. This study examines the traffic performance at the unsignalized four-way intersection of Jalan Raya Kepuharjo – Jalan Balai Desa Kepuharjo – Jalan Pertamanan in Malang, which is one of the intersections not equipped with traffic signals. This unsignalized four-way intersection is surrounded by a store, a factory, and a school. Its main road, Jalan Raya Kepuharjo, serves as a bus and truck route connecting Malang City and Batu City, thus potentially causing congestion. The aim of this study is to evaluate the intersection's performance by analyzing its capacity, degree of saturation, delay, and level of service, which can help identify improvement alternatives if the intersection's performance is found to be suboptimal. Traffic data were collected through field surveys during peak morning to evening periods. The analysis method refers to the Indonesian Highway Capacity Manual (MKJI) of 1997, published by the Directorate General of Highways. The results of the traffic performance study at the unsignalized four-way intersection of Jalan Raya Kepuharjo – Jalan Balai Desa Kepuharjo – Jalan Pertamanan in Malang indicate that the intersection's capacity is significantly influenced by traffic volume and vehicle composition, as reflected by the degree of saturation (DS) value of 1,17. This study suggests alternative traffic management strategies to improve the efficiency and performance of the unsignalized four-way intersection. The conclusions from this research are expected to contribute to better urban transportation planning
