ABSTRAK

Peningkatan kebutuhan masyarakat terhadap penggunaan kendaraan bermotor seirama dengan peningkatan volume kendaraan bermotor, kemudian berakibat pada potensi terjadinya kemacetan lalu lintas terutama pada jam padat arus. Langkah penanganan yang dilakukan dengan pengaturan lampu lalu lintas (traffic light) yang diletakkan pada ujung persimpangan, seperti pada simpang tiga bersinyal Jalan Mayjend Sutoyo S.- Jalan Jafri Zam-Zam. Simpang bersinyal memiliki peran penting dalam mengatur dan menertibkan arus lalu lintas. Akan tetapi, justru sering terjadi kemacetan pada simpang bersinyal. Hal ini terjadi akibat ketidaksesuaian pengaturan dengan fakta lapamgan sehingga berdampak pada kinerja simpang bersinyal.

Dalam proses analisa kinerja simpang menggunakan metode pengambilan data survey lapangan pada hari Rabu 6 Maret 2024 dan Kamis 7 Maret 2024 selama 24 jam pada pukul 06.00-06.00 WITA. Pedoman analisis data menggunakan Pedoman Kapasitas Jalan Indonesia (PKJI 2023). Berdasarkan hasil analisis didapatkan arus pada jam puncak terjadi pada pukul 07.00-08.00 WITA dengan hasil kondisi eksisting simpang dengan Derajat Kejenuhan (DJ) = 1,27 Tundaan Simpang (D) = 47,26, dengan tingkat pelayanan E yang artinya arus tidak stabil. Kemudian dilakukan alternatif perbaikan sebagai solusi pada permasalahan ini yaitu pelebaran pendekat dan pengaturan ulang waktu sinyal yang mana dilihat dari segi tundaan rata-rata simpang sebesar 24,70 detik/smp, derajat kejenuhan sebesar 0,76 dengan indeks tingkat pelayanan C memenuhi standar Permenhub No.14 Tahun 2006.

Kata Kunci : Simpang Bersinyal, Derajat Kejenuhan, Lalu Lintas.

ABSTRACT

The increase in public demand for the use of motorized vehicles is in line with the increase in the volume of motorized vehicles, which then results in the potential for traffic jams, especially during peak traffic hours. Handling steps are carried out by setting traffic lights that are placed at the end of intersections, such as at the signalized intersection of Mayjend Sutoyo S. street - Jafri Zam-Zam street. Signalized intersections have an important role in regulating and controlling traffic flow. However, traffic jams often occur at signalized intersections. This occurs due to a mismatch between the regulations and field facts, which has an impact on the performance of signalized intersections.

In the process of analyzing intersection performance using the field survey data collection method on Wednesday, 6 March 2024 and Thursday, 7 March 2024 for 24 hours at 06.00-06.00 WITA. Data analysis guidelines use the Indonesian Road Capacity Guidelines 2023. Based on the results of the analysis using the Indonesian road capacity guideline method (PKJI 2023 Based on the analysis results, it was found that the peak hour flow occurred at 07.00-08.00 WITA with the results of the existing intersection conditions with Degree of Saturation (DJ) = 1.27 Intersection Delay (D) = 47.26, with service level E which means the flow is unstable. Then an alternative improvement was carried out as a solution to this problem, namely widening the approach and resetting the signal time, which in terms of the average delay at the intersection was 24.70 seconds/pcu, the degree of saturation was 0.76 with a service level index C, that it met standard of Transportation Regulation No.14 of 2006.
