PERFORMANCE ANALYSIS OF THE TAMANSARI ROAD - SULANJANA ROAD NTERSECTION IN BANDUNG CITY USING PTV VISSIM SOFTWARE

Sari

ABSTRAK

Penelitian ini membahas kinerja persimpangan tidak bersinyal Jalan Tamansari – Jalan Sulanjana yang sering mengalami tundaan dan antrean akibat tingginya volume kendaraan. Analisis dilakukan menggunakan metode Bina Marga No. 09/P/BM/2023 dan simulasi software PTV Vissim, dengan data diperoleh melalui survei lapangan. Hasil analisis menunjukkan kapasitas sebesar 2.856 smp/jam dan derajat kejenuhan 0,84 yang menandakan kondisi hampir jenuh. Peluang antrean berkisar antara 28–56%, dengan tundaan rata-rata 15 dtk/smp dihasilkan dari tundaan lalu lintas sebesar 10 dtk/smp dan tundaan geometrik sebesar 5 dtk/smp. Simulasi Vissim menunjukkan panjang antrean maksimum antara 18–40 meter dan tundaan 8–14 detik pada tiap pendekat. Nilai LOS keseluruhan adalah B, dengan variasi pendekat Timur LOS C, pendekat Utara LOS A, pendekat Barat LOS A, dan pendekat Selatan LOS B. Secara umum, simpang berada dalam kondisi kritis dan sangat rentan terhadap gangguan lalu lintas.

ABSTRACT

This study discusses the performance of the unsignalized intersection of Tamansari Road and Sulanjana Road, which often experiences delays and queues due to high vehicle volume. The analysis was conducted using the Bina Marga No. 09/P/BM/2023 method and PTV Vissim simulation software, with data obtained through field surveys. The analysis results show a capacity of 2,856 vehicles per hour and a saturation level of 0.84, indicating near-saturation conditions. The queue probability ranges from 28–56%, with an average delay of 15 seconds/vehicle resulting from a traffic delay of 10 seconds/vehicle and a geometric delay of 5 seconds/vehicle. The Vissim simulation shows a maximum queue length of 18–40 meters and a delay of 8–14 seconds at each approach. The overall LOS value is B, with variations in the East approach LOS C, North approach LOS A, West approach LOS A, and South approach LOS B. In general, the intersection is in a critical condition and is highly vulnerable to traffic disruptions.
