Pengaturan lalulintas pada bundaran merupakan hal yang sangat penting dan perlu diperhatikan dalam pergerakan lalulintas pada jaringan jalan dalam kota. Bundaran harus direncanakan dengan sebaik mungkin, sehingga tidak menimbulkan kemacetan pada arus lalu lintas. Penelitian ini bertujuan untuk menganalisis kinerja Bundaran UGM Yogyakarta. Metodologi yang digunakan adalah dengan menggunakan metode survei lapangan dan analisis data yang mengacu pada Manual Kapasitas Jalan Indonesia (MKJI 1997). Hasil analisis yang didapat kondisi eksisting diperoleh nilai nilai DS tertinggi pada bagian jalinan DA sebesar 0,938 dan nilai tundaan 14,889 det/smp dengan tingkat pelayanan kategori C. Sesuai dengan Peraturan Menteri Perhubungan RI No. 96 Tahun 2015 tentang Manajemen dan Rekayasa Lalu Lintas di Jalan, nilai tersebut masih belum sesuai dengan ketentuan. Maka dilakukan adanya alternatif agar dapat memenuhi nilai yang sudah ditentukan. Alternatif – I yaitu melakukan penutupan akses dari pendekat B dan C menuju pendekat A dengan hasil DS 0,590 dan nilai tundaan 4,204 det/smp didapat tingkat pelayanan kategori A. Alternatif II yaitu melakukan pelebaran pada diameter bundaran dengan hasil DS 0,798 dan nilai tundaan 14,609 det/smp didapat tingkat pelayanan kategori B. Berdasarkan alternatif yang telah dilakukan, direkomendasikan menggunakan alternatif I dengan nilai tundaan yang lebih kecil sebesar 4,204.
Traffic regulation on roundabouts is very important and needs to be considered in the overall traffic movement on the road network in the city.. The purpose of this study was to analyze the performance of the traffic circle of the Gadjah Mada University in Yogyakarta. In this study, analytical method used was the 1997 Indonesian Road Capacity Manual on the part of the roundabout fabric. The results of the analysis obtained the existing condition obtained the highest DS value in the DA braid section of 0.938 and the delay value of 14,889 det / pcu with the service level C category. In the Republic of Indonesia Minister of Transportation regulation No. 96 of 2015 on Management and traffic engineering, the value not in accordance with the provisions. Then there is an alternative so that it can meet the determined value. Alternative - I is closing the access of closers closers B and C to the A with a DS 0590 and 4204 of the delay sec/smp obtained service level category A. Alternative II that widen the diameter of the roundabouts with DS 0798 and the results of the delay is 14 609 sec/smp obtained service level category B. Based on two alternatives that have been done; it is recommended to use alternative I with a smaller delay value of 4.204
