Abstract

The average growth of motor vehicles in Jakarta reaches 3.6% per year triggers congestion, especially when intersections lack proper design and signal settings. The Fatmawati intersection is linking primary arterials and secondary collectors vital for business mobility, but often experiences delays due to geometric inconsistencies and increased traffic from toll ramp exits. This study aims to analyse the existing performance of the Fatmawati intersection based on the 2023 Indonesian Road Capacity Guidelines (PKJI 2023) and to propose optimization through microscopic simulation using PTV VISSIM software validated with the GEH statistical test. Results indicate that the intersection is in poor condition, with a degree of saturation of 0.86, maximum queue length of 271.1 meters, and average delay of 84.88 sec/SMP. The model is considered valid with GEH values below 5, indicating alignment between simulated and observed vehicle volumes and queue lengths with PKJI 2023 analysis, with lateral queue diamond parameters adjusted specifically for motorcycles. Optimization scenarios involving cycle time reduction, right-turn restrictions, geometric widening, and signal coordination resulted in queue length reductions of up to 59% and delay reductions of up to 53%. This study confirms that simple geometric modifications combined with adaptive signal settings can improve the performance of urban intersections.
