Abstract

Bundaran Cibeureum merupakan simpang bundaran empat lengan di Kota Bandung yang tiga lengan masuknya telah dikendalikan Alat Pemberi Isyarat Lalu Lintas (APILL) tiga fase, sehingga kinerjanya ditentukan oleh dua lapis, yaitu bagian jalinan (PKJI 2023 Bab 7) dan pendekat ber-APILL (PKJI 2023 Bab 5). Penelitian ini bertujuan menganalisis kondisi geometrik dan kinerja lalu lintas eksisting, menilai dampak rencana jalur khusus Bus Rapid Transit (BRT) di sepanjang Jalan Jenderal Sudirman, serta menyusun rekomendasi perbaikan. Data diperoleh dari survei lalu lintas jam puncak pagi dan sore, dianalisis dengan PKJI 2023, dan disimulasikan dengan PTV Vissim. Hasil menunjukkan derajat kejenuhan bagian jalinan tertinggi 0,704 pagi dan 0,803 sore, memenuhi kriteria 0,85, tetapi derajat kejenuhan pendekat kritis mencapai 1,00 pagi dan 1,39 sore, dengan panjang antrean 154 m dan 179 m serta angka henti 0,903 dan 1,051 stop/smp, sehingga kinerja simpang dikendalikan oleh lapis pendekat. Jalur khusus BRT menurunkan kapasitas lebih besar daripada arus sehingga memperburuk seluruh indikator kinerja. Dari skenario perbaikan yang diuji, Skenario 1b berupa penyederhanaan fase APILL menjadi dua fase bersiklus sekitar 50 detik memenuhi lima dari enam kriteria, termasuk kriteria derajat kejenuhan pendekat kritis yang selama ini mengikat kinerja simpang, tanpa memerlukan pembebasan lahan, sehingga direkomendasikan sebagai perbaikan jangka pendek. Kriteria derajat kejenuhan bagian jalinan pada jam puncak sore tidak dapat dicapai oleh satu pun skenario, karena kapasitas bagian jalinan hanya ditentukan oleh besaran geometrik dan rasio jalinan, sedangkan perubahan geometri berada di luar batasan penelitian ini. Kata kunci: bundaran, bagian jalinan, derajat kejenuhan, Bus Rapid Transit, PKJI 2023 ----------------------------------------------------------- Cibeureum Roundabout is a four-arm roundabout in Bandung whose three entry arms are already controlled by a three-phase traffic signal, so its performance is governed by two layers: the weaving sections (PKJI 2023 Chapter 7) and the signalised approaches (PKJI 2023 Chapter 5). This study analyses the existing geometric conditions and traffic performance, assesses the impact of the planned Bus Rapid Transit (BRT) exclusive lane along Jalan Jenderal Sudirman, and formulates improvement recommendations. Data were obtained from morning and afternoon peak-hour traffic surveys, analysed using PKJI 2023, and simulated with PTV Vissim. Results show the highest weaving-section degree of saturation is 0.704 (morning) and 0.803 (afternoon), meeting the 0.85 criterion, while the critical approach degree of saturation reaches 1.00 and 1.39, with queue lengths of 154 m and 179 m and stop rates of 0.903 and 1.051 stops per passenger car unit, showing that performance is governed by the approach layer. The BRT lane reduces capacity more than flow, worsening every indicator. Among three tested scenarios, Scenario 1b, simplifying signal phasing to two phases with a cycle of about 50 seconds, meets five of the six criteria, including the critical approach criterion that governs the intersection, without land acquisition, and is recommended as the short-term improvement. The weaving-section criterion in the afternoon peak is met by none of the scenarios, because weaving capacity depends only on geometry and the weaving ratio, and geometric change lies outside the scope of this study.
