Pertumbuhan aktivitas perkotaan di kawasan permukiman dan perdagangan berdampak langsung pada meningkatnya hambatan samping, yaitu gangguan yang berasal dari aktivitas di sisi jalan. Hambatan samping dapat menurunkan kapasitas jalan, memperlambat kecepatan kendaraan, dan meningkatkan derajat kejenuhan sehingga perlu mendapat perhatian khusus pada ruas jalan dengan aktivitas tinggi di sisi jalannya. Penelitian ini bertujuan menganalisis karakteristik hambatan samping serta pengaruhnya terhadap kinerja Ruas Jalan Rama Setia, Kota Banda Aceh, yang merupakan jalan kolektor sekunder perkotaan bertipe dua lajur dua arah tidak terbagi (2/2 TT). Metode analisis mengacu pada Pedoman Kapasitas Jalan Indonesia (PKJI) 2023 dan dilengkapi analisis regresi linear. Data dikumpulkan melalui survei lapangan selama 12 jam (07.00-19.00), meliputi geometrik jalan, volume lalu lintas, hambatan samping pada segmen 200 meter, dan kecepatan kendaraan pada segmen 50 meter. Hasil penelitian menunjukkan bahwa hambatan samping didominasi oleh aktivitas kendaraan parkir di badan jalan (PSV) dan kendaraan keluar-masuk akses samping jalan (EEV). Kelas hambatan samping bervariasi dari Rendah (R) pada pagi hari hingga Tinggi (T) pada sore hari, dengan nilai tertinggi sebesar 850,30 kejadian/jam pada pukul 17.00-18.00. Kapasitas jalan menurun dari 2.700 smp/jam pada kondisi hambatan rendah menjadi 2.066 smp/jam pada kondisi hambatan tinggi, atau turun sebesar 23,48%. Nilai derajat kejenuhan berkisar antara 0,17 hingga 0,54 dengan tingkat pelayanan LOS A hingga LOS C, menunjukkan kondisi arus lalu lintas masih stabil dan belum mencapai kondisi kritis. Analisis regresi linear mengonfirmasi bahwa hambatan samping berpengaruh negatif terhadap kecepatan kendaraan (R² = 0,972) dan kapasitas jalan (R² = 0,912), serta berpengaruh positif terhadap derajat kejenuhan (R² = 0,921). Nilai R² yang tinggi pada ketiga model membuktikan bahwa hambatan samping merupakan variabel dominan dalam menjelaskan perubahan kinerja Ruas Jalan Rama Setia, khususnya pada periode sore hari pukul 16.00-19.00.

The growth of urban activities in residential and commercial areas has directly contributed to the increase in roadside friction, which refers to disturbances caused by activities along the road. Side friction can reduce road capacity, decrease vehicle speed, and increase the degree of saturation, making it an important factor to consider on road segments with intensive roadside activities. This study aims to analyze the characteristics of side friction and its influence on the performance of Rama Setia Road in Banda Aceh City, which is classified as a two-lane, two-way undivided (2/2 UD) urban collector road. The analysis was conducted based on the Indonesian Road Capacity Guidelines (PKJI) 2023 and supported by linear regression analysis. Data were collected through a 12-hour field survey (07:00–19:00), including road geometric characteristics, traffic volume, side friction on a 200-meter road segment, and vehicle speed on a 50-meter road segment. The results indicate that side friction was predominantly caused by parked vehicles on the roadway (PSV) and vehicles entering and exiting roadside access points (EEV). The side friction level varied from Low (L) in the morning to High (H) in the afternoon, with the highest weighted value reaching 850.30 events/hour during the 17:00–18:00 period. Road capacity decreased from 2,700 pcu/hour under low side friction conditions to 2,066 pcu/hour under high side friction conditions, representing a reduction of 23.48%. The degree of saturation ranged from 0.17 to 0.54, corresponding to Level of Service (LOS) A to LOS C, indicating that traffic flow remained stable and had not yet reached critical conditions. Linear regression analysis confirmed that side friction had a negative effect on vehicle speed (R² = 0.972) and road capacity (R² = 0.912), while exerting a positive effect on the degree of saturation (R² = 0.921). The high coefficients of determination obtained from all three models indicate that side friction is the dominant factor affecting the performance of Rama Setia Road, particularly during the afternoon peak period between 16:00 and 19:00.
