ANALISIS KINERJA SIMPANG BERSINYAL DAN BIAYA OPERASIONAL KENDARAAN PADA JALAN GALUNGGUNG – JALAN RAYA TIDAR – JALAN BONDOWOSO KOTA MALANG

Abstract

Increased traffic flow at crossroads that doesn’t have a suitable infrastructure can cause traffic jam. The traffic jam that occurs also has an impact on vehicle operating cost that passing through the intersection. On the page malangchannel.com, the intersection at Jalan Galunggung, Jalan Raya Tidar and Jalan Bondowoso is one of the points in Malang City that have high frequently traffic jams. Congestion occurs because there are many motorized vehicles across to the area, where the area around the location has a shops, malls, campuses, and others. This study aims to find how much the intersection Level Of Service (LOS) and the vehicle operating costs that passing through the intersection and give the best solution in order to improve the performance of the intersection and reduce the vehicle operating cost. The data used include the geometric of intersection, traffic signals, side friction, traffic volume during peak hours, average speed of vehicles during peak hours and components of vehicle operating costs. The calculation of intersection performance using MKJI 1997, vehicle operating costs using Pacific Consultant International (PCI) and intersection congestion costs using Tzedakis 1980. The calculation results show that the existing condition of the intersection has passed the saturation point with the service level (LOS) F of and the average vehicle delay 1013.6 sec / pcu and the congestion cost Rp. 86,744,635 / hour for light vehicles (LV). and IDR 15,424,569 / hour for heavy vehicles (HV). Alternative improvements of intersection by resetting the phases from 2 to 4, road geometric adjustment and adding the flyovers, the congestion costs can be reduced to Rp. 1,319,498 / hour for light vehicles (LV) and Rp. 231,244 / hour for heavy vehicles (HV) with the Level Of Service (LOS) B from average delay of vehicle 14.5 sec / pcu.
