<![CDATA[Abstract: This study aims to determine the effect of side barriers on the performance of Jalan A. Rivai in the Kisaran night culinary tourism area. The method used was an observational study with a traffic volume survey for seven consecutive days in November 2025. Data was collected through direct counts of light vehicles, heavy vehicles, and motorcycles using traffic counters. The analysis included calculating traffic volume (Q), road capacity (C), degree of saturation (DJ), free-flow speed (FV), and the frequency of side barriers. The results showed the highest volume on Sunday with 1,219 vehicles and a Q of 273.4 pcu/h, a road capacity of 1,952.8 pcu/h, a degree of saturation of 0.14, and a free-flow speed of 30.19 km/h. The greatest side barriers occurred on Sunday nights due to vehicle parking and street vendors on the roadside. However, these barriers did not significantly impact road performance. This study recommends shoulder space management and parking management to maintain smooth traffic flow in the area. Keywords: Side barriers, road performance, level of service, traffic volume, night culinary tourism. Abstrak: Penelitian ini bertujuan mengetahui pengaruh hambatan samping terhadap kinerja ruas Jalan A. Rivai di kawasan wisata kuliner malam Kisaran. Metode yang digunakan adalah studi observatif dengan survei volume lalu lintas selama tujuh hari berturut-turut pada November 2025. Data dikumpulkan melalui penghitungan langsung kendaraan ringan, berat, dan sepeda motor menggunakan traffic counter. Analisis meliputi perhitungan volume lalu lintas (Q), kapasitas jalan (C), derajat kejenuhan (DJ), kecepatan arus bebas (FV), dan frekuensi hambatan samping. Hasil menunjukkan volume tertinggi pada hari Minggu dengan 1.219 kendaraan dan Q sebesar 273,4 smp/jam, kapasitas jalan sebesar 1.952,8 smp/jam, derajat kejenuhan 0,14, dan kecepatan arus bebas 30,19 km/jam. Hambatan samping terbesar terjadi pada hari Minggu malam disebabkan aktivitas parkir kendaraan dan pedagang kaki lima di bahu jalan. Meski demikian, hambatan ini belum berpengaruh signifikan terhadap kinerja jalan. Penelitian ini merekomendasikan penataan ruang bahu jalan dan pengelolaan parkir untuk menjaga kelancaran lalu lintas di kawasan tersebut. Kata kunci: Hambatan samping, kinerja jalan, tingkat pelayanan, volume lalu lintas, wisata kuliner malam.]]>
