Analisis Kinerja Simpang tak Bersinyal Jalan Simpang Empat Cicariang Berdasarkan PKJI 2023

Abstract

Intersection refers to an area where two or more road branches meet or cross, requiring supporting facilities to manage traffic movement effectively. The study location is the unsignalized four-way intersection at Cicariang Kawalu, Tasikmalaya City. The objective of this research is to analyze the traffic volume and evaluate the performance of the intersection. The method applied in this study follows the Indonesian Road Capacity Guidelines (PKJI 2023). Field surveys were conducted to collect average daily traffic volume data to determine capacity calculations, delays, degree of saturation, and queue probabilities. The results of the analysis for the unsignalized four-way intersection at Cicariang Kawalu, Tasikmalaya City, indicate that the peak traffic volume occurred on Monday, April 22, 2024, between 06:00 and 07:00 WIB, with a vehicle count of 2,184.2. The intersection capacity was calculated at 2,522.14 vehicles per hour, with an approach width of 3.125 meters. The degree of saturation was 0.866 seconds per vehicle, with intersection traffic delays averaging 10.77 seconds per vehicle. Major road delays were 7.87 seconds per vehicle, minor road delays 12.967 seconds per vehicle, geometric delay at the intersection 4.110 seconds per vehicle, and total intersection delay 14.88 seconds per vehicle, corresponding to a Level of Service (LOS) B. Queue probability was estimated at 34.44% for the lower bound and 59.48% for the upper bound, indicating a stable traffic flow zone. Drivers experienced restricted freedom in selecting their speeds.
