Alternatif Peningkatan Kapasitas Ruas Jalan dengan Pendekatan Manajemen Lalu Lintas (Studi Kasus: Jalan Jamin Ginting, Sman 1 Pancur Batu-Simpang Tuntungan)

Abstract

Jalan merupakan salah satu prasarana transportasi angkutan darat yang berf ungsi sebagai penghubung antara daerah satu dengan daerah lainya serta mempunyai peran penting dalam bidang, perekenomian, pariwisata, social budaya dan lainlainya. Dalam sistem transportasi perkotaan di wilayah Kabupaten Deli Serdang, ruas Jalan Jamin Ginting berfungsi sebagai jalur penghubung kota Medan dengan Kabupaten Karo. Jalan lintas Jamin Ginting berperan sebagai jalan utama yang digunakan oleh pemakai jalan menuju pusat kota maupun luar kota.Keadaan ini menyebabkan tingginya tingkat kebutuhan akan pergerakan lalu lintas masyarakat kota Medan dan sekitarnya. Penelitian ini dilakukan dengan pengumpulan data, baik data primer yang terdiri dari survei volume kendaraan dan data sekunder yang diperoleh dari instansi terkait. Analisis tingkat pelayanan jalan pada ruas jalan lintas jamin ginting ini diolah menggunakan metode Bina Marga dengan panduan Manual Kapasitas Jalan Indonesia (MKJI 1997). Road is one of the land transportation transportation infrastructure that functions as a liaison between one region and another and has an important role in the economic, tourism, socio-cultural and other fields. In the urban transportation system in the Deli Serdang Regency, the Jalan Jamin Ginting section serves as a link between the city of Medan and Karo Regency. The Jamin Ginting causeway acts as the main road used by road users to the city center and outside the city. This situation causes a high level of demand for traffic movements for the people of Medan and its surroundings. This research was conducted by collecting data, both primary data consisting of vehicle volume surveys and secondary data obtained from related agencies. The analysis of the level of road service on this guaranteed ginting cross-road was processed using the Bina Marga method with the guidance of the Indonesian Road Capacity Manual (MKJI 1997). Based on the results of the field survey, the first location of observation has a volume of 2109.25 pcu/hour and is the densest. The capacity at the first location of observation is 4766.58 pcu/hour, so the degree of saturation is 0.45 pcu/hour. The 1997 Indonesian Road Capacity Manual recommends that if the degree of saturation > 0.75 is obtained, it is necessary to make improvements to the road, both physically and in traffic control. This means that at the first observation location on the Jamin Ginting Pancur Batu road, it still meets the requirements, and does not need to be improved. The average speed at the first location of observation was 15 km/hour which was dominated by motorcycles with a side resistance weight frequency of 127.5 which was classified in the Low category (MKJI, 1997).
