HUBUNGAN VOLUME, KECEPATAN DAN KEPADATAN LALU LINTAS PADA RUAS JALAN PADJAJARAN (RING ROAD UTARA), SLEMAN

Abstract

A macroscopic movement of traffic consists of traffic volume, speed and density which are used to evaluate the quality of transportation system. By analyzing these variables, a result which inform about the condition about a transportation system will be provided. Analysis results shows the traffic condition through the traffic volume and density. When a road has a bad condition of transportation system, the analysis will describe it as high density of traffic and the maximum traffic volume is exceeded. This research is conducted on Padjajaran Street to evaluate its characteristic of transportation system. Data, which were collected, consists of traffic volume and spot-speed on every lane of the street. Those were collected on Monday, Wednesday, Saturday and Sunday at peak-hours, which are 6.30am-8.30am, 11am-1pm and 4pm-6pm. The vehicles classification refers to MKJI 1997 and conducted an analysis through several models, which are Greenshield, Greenberg, Underwood and Bell models. Most of lanes are well-modelled using Underwood method. Finally, it comes to a conclusion that Padjajaran Street is classified as urban road.
