Abstract
Pertumbuhan volume lalu lintas di kawasan perkotaan yang tidak diimbangi dengan peningkatan kapasitas jalan dapat menurunkan kinerja ruas jalan, terutama pada fasilitas putar balik arah (U-turn). U-turn yang beroperasi pada ruas dengan arus lalu lintas tinggi berpotensi menimbulkan konflik, tundaan, dan antrian kendaraan yang berdampak pada kelancaran serta keselamatan lalu lintas. Tidak hanya dari segi arus lalulintas saja, geometrik U-Turn itu sendiri dapat menjadi permasalahan yang dapat menimbulkan konflik di sekitar area tersebut. Penelitian ini bertujuan untuk menganalisis kinerja U-turn pada ruas Jalan Boulevard Bintaro Jaya, khususnya di sekitar kawasan depan SPBU BP/Fresh Market Bintaro, berdasarkan parameter kinerja lalu lintas. Metode penelitian yang digunakan adalah analisis kinerja lalu lintas mengacu pada Pedoman Kapasitas Jalan Indonesia (PKJI) Tahun 2023. Data primer diperoleh melalui survei lalu lintas pada jam puncak pagi, siang, dan sore hari, yang meliputi volume lalu lintas, kecepatan kendaraan, dan hambatan samping. Data hasil survei kemudian dianalisis untuk menentukan nilai kecepatan arus bebas, kapasitas jalan, derajat kejenuhan, tundaan, panjang antrian kendaraan, serta tingkat pelayanan (Level of Service). Hasil analisis menunjukkan bahwa pada kondisi jam puncak, U-turn di lokasi penelitian mengalami peningkatan tundaan dan panjang antrian kendaraan akibat tingginya volume lalu lintas dan adanya konflik dengan arus utama. Nilai derajat kejenuhan yang diperoleh 0,26 menunjukkan bahwa kinerja jalan berada pada kondisi arus stabil, hambatan mulai terasa. Akan tetapi dari segi geometrik U-Turn diperlukan adanya evaluasi karena ada beberapa kriteria yang belum memenuhi standar menurut Pedoman Perencanaan Putar Balik menurut Bina Marga tahun 2005, hal ini diperlukan guna meningkatkan kinerja U-turn serta kelancaran arus lalu lintas pada ruas Jalan Boulevard Bintaro Jaya. The growth of traffic volume in urban areas that is not accompanied by an increase in road capacity can reduce road performance, particularly at U-turn facilities. Uturns operating on roads with high traffic flow have the potential to create conflicts, delays, and vehicle queues, which negatively affect traffic flow and safety. In addition to traffic flow conditions, the geometric design of the U-turn itself can also become a problem that contributes to conflicts in the surrounding area. This study aims to analyze the performance of a U-turn on Boulevard Bintaro Jaya Road, specifically in the area in front of the BP Gas Station/Fresh Market Bintaro, based on traffic performance parameters. The research method employed is traffic performance analysis, referring to the Indonesian Highway Capacity Guidelines (PKJI) 2023. Primary data were obtained through traffic surveys conducted during morning, midday, and evening peak hours, including traffic volume, vehicle speed, and side friction. The collected data were then analyzed to determine free-flow speed, road capacity, degree of saturation, delay, queue length, and level of service (LOS). The analysis results indicate that during peak-hour conditions, the U-turn at the study location experiences increased delays and vehicle queue lengths due to high traffic volumes and conflicts with the main traffic stream. The obtained degree of saturation value of 0.26 indicates that the road operates under stable flow conditions, where side friction effects begin to be noticeable. However, from a geometric perspective, the U-turn requires further evaluation, as several criteria do not meet the standards specified in the U-Turn Planning Guidelines issued by Bina Marga (2005). Therefore, improvements are necessary to enhance the performance of the U-turn and to improve traffic flow conditions on Boulevard Bintaro Jaya Road.
