However, this issue faces complex challenges, especially in schools located on strategic road corridors. The purpose of this study is to describe the traffic conditions of Ragunan Street, the factors that cause congestion on Ragunan Street at peak time and to describe the performance of the street located at the School Safety Zone (Zoss) of SMAN 28 Pasar Minggu, South Jakarta at peak times. The primary data source was obtained through traffic counting with a quantitative descriptive approach. The study population was passenger cars and motorbikes passing through Ragunan Street. The data analysis technique refers to the procedure for calculating urban roads according to the Indonesian Road Capacity Manual (MKJI) 1997. The results show that the performance of Ragunan Street is as follows; free flow speed of 57.52 km/hour, capacity 6,552 pcu/hour, the level of road service ranges from B to D. The degree of saturation is below 0.75 indicating the road capacity still meets the MKJI 1997 standard except for the direction of Kalibata-Pasar Minggu which scores 0.80 with a value of D. The speed in the ZoSS of SMAN 28 area is 57.52km/hour, significantly exceeding the maximum speed limit of 20-25 km/hour implying it is critical for pedestrians in the ZoSS area. Keywords : road performance, school safety zone, pedestrians, strategic road corridors ABSTRAK Tujuan penelitian ini untuk mengetahui gambaran kondisi lalu lintas ruas jalan Raya Ragunan, faktor-faktor penyebab kemacetan pada ruas jalan Raya Ragunan saat peak time dan gambaran kinerja ruas Jalan Raya Ragunan pada Zona Selamat Sekolah (Zoss) SMAN 28 Pasar Minggu Jakarta Selatan pada saat peak time. Zona Selamat Sekolah (ZoSS) dibuat untuk pengaturan lalu lintas pada waktu tertentu di area dekat dengan sekolah untuk memastikan keselamatan khususya pejalan kaki pada wilayah tersebut. Namun demikian, tujuan ini menghadapi tantangan yang kompleks terutama pada sekolah-sekolah yang terletak pada koridor jalan strategis. Sumber data primer diperoleh melalui traffic counting dengan pendekatan deskriptif kuantitatif. Populasi penelitian adalah kendaraan mobil penumpang dan motor yang melintas di ruas Jalan Raya Ragunan. Teknik analisa data mengacu pada prosedur perhitungan jalan perkotaan menurut Manual Kapasitas Jalan Indonesia (MKJI)
