ABSTRAK
Simpang bersinyal Jalan Raden Saleh – Jalan S. Parman – Jalan Sam Ratulangi merupakan salah satu simpang penting di Kota Palu yang melayani pergerakan dari kawasan perkantoran, perdagangan, dan permukiman. Tingginya volume kendaraan pada jam puncak menimbulkan antrean dan tundaan, sehingga perlu dilakukan evaluasi kinerja simpang. Penelitian ini bertujuan menganalisis kinerja simpang bersinyal berdasarkan Pedoman Kapasitas Jalan Indonesia (PKJI) 2023 serta merumuskan alternatif penanganan. Data diperoleh melalui survei volume lalu lintas, kondisi geometrik simpang, pengaturan waktu sinyal APILL, dan kondisi lingkungan sekitar simpang. Hasil penelitian menunjukkan bahwa kondisi hari kerja merupakan kondisi paling kritis dengan volume 1.819,25 smp/jam, lebih tinggi dibandingkan hari libur sebesar 1.235,95 smp/jam. Pada kondisi eksisting, tundaan rata-rata mencapai 88,96 detik/smp dengan tingkat pelayanan LOS F. setelah dilakukan penanganan melalui pengaturan ulang APILL menjadi tiga fase dengan waktu siklus 49 detik, tundaan rata-rata menurun menjadi 24,44 detik/smp dan tingkat pelayanan meningkat menjadi LOS C. dengan demikian, alternatif penanganan tersebut efektif memperbaiki kinerja simpang.

ABSTRACT
The signalized intersection of Raden saleh Street – S. Parman Street – Sam Ratulangi Street is one of the major intersections in Palu City, serving traffic movemoments from office, commercial, and residential areas. High traffic volumes during peak hours result in queues and delays, necessitating an evaluation of the intersection´s performance. This study aims to analyze the performance of the signalized intersection based on the 2023 Indonesian Highway Capacity Guidelines (PKJI 2023) and to formulate an appropriate improvement alternative. Data were collected through surveys of traffic volume, intersection geometric conditions, traffic signal timing, and the surrounding environmental conditions. The results indicate that weekdays represent the most critical condition, with a traffic volume of 1,819.25 passenger car units per hour (pcu/hour), wich is higher than the 1,235.95 pcu/hour recorded on holidays. Under existing conditions, the average delay reached 88.96 seconds per passenger car unit (s/pcu), corresponding to Level of Service of (LOS) F. Following an improvement involving the reconfiguration of the traffic signal system into three phasess with a cycle length of 49 seconds, the average delay decreased to 24.44 seconds/pcu, while the Level of Service improved to LOS C. Therefore, the proposed improvement alternative is effective in enchancing the performance of the intersection.
