ANALISIS FAKTOR PENYEBAB KEMACETAN LALU LINTAS DI JALAN DIPONEGORO PASAR KAJEN

Kemacetan lalu lintas merupakan permasalahan umum yang sering terjadi di kawasan perkotaan, terutama pada area dengan aktivitas ekonomi tinggi seperti pasar tradisional. Penelitian ini bertujuan untuk menganalisis kinerja lalu lintas dan mengidentifikasi faktor-faktor penyebab kemacetan di Jalan Diponegoro Pasar Kajen, Kabupaten Pekalongan. Metode penelitian menggunakan pendekatan survei lapangan dengan pengumpulan data primer berupa volume lalu lintas, kecepatan arus bebas, dan kapasitas jalan. Analisis dilakukan mengacu pada Pedoman Kapasitas Jalan Indonesia (PKJI) 2023.Hasil penelitian menunjukkan bahwa volume lalu lintas tertinggi terjadi pada hari Senin pukul 07.00-08.00 WIB sebesar 1.848,05 smp/jam, dengan kapasitas jalan sebesar 2.156 smp/jam. Kecepatan arus bebas tercatat 32,34 km/jam, dan nilai derajat kejenuhan (DS) tertinggi mencapai 0,87, yang menunjukkan Level of Service (LOS) kategori E atau arus jenuh. Faktor utama penyebab kemacetan meliputi tingginya aktivitas pasar, parkir di bahu jalan, perilaku pengemudi yang tidak tertib, minimnya fasilitas penunjang lalu lintas, serta tingginya hambatan samping.Penelitian merekomendasikan penerapan rekayasa lalu lintas, penataan ulang area pasar, larangan parkir di bahu jalan saat jam sibuk, dan peningkatan fasilitas penunjang seperti trotoar, penyeberangan, serta rambu lalu lintas untuk meningkatkan kelancaran arus lalu lintas di kawasan
tersebut.

Traffic congestion is a common problem frequently found in urban areas, especially in locations with high economic activity such as traditional markets. This study aims to analyze traffic performance and identify the factors causing congestion on Jalan Diponegoro, Kajen Market, Pekalongan Regency. The research employed a field survey approach, collecting primary data including traffic volume, free-flow speed, and road capacity. The analysis was conducted based on the Indonesian Highway Capacity Manual (PKJI) 2023.The results show that the highest traffic volume occurred on Monday at 07.00-08.00 WIB, reaching 1,848.05 pew/hour, with a road capacity of 2,156 pcw/hour. The recorded free-flow speed was 32.34 km/h, and the highest degree of saturation (DS) reached 0.87, indicating a Level of Service (LOS) category E or saturated flow. The main factors contributing to congestion include high market activity, on-street parking. undisciplined driver behavior, lack of supporting traffic facilities, and high roadside friction. The study recommends implementing traffic engineering measures, reorganizing the market area, enforcing no-parking policies during peak hours, and improving supporting facilities such as sidewalks, pedestrian crossings, and traffic signs to enhance traffic flow in the area.
