ANALISA KINERJA BUNDARAN MENGGUNAKAN METODE MANUAL KAPASITAS JALAN INDONESIA (MKJI) (SUDI KASUS : BUNDARAN RADIN INTEN BANDAR LAMPUNG)

Abstract

Radin Inten roundabout is one of the important roundabout in the city of Bandar Lampung , which serves traffic from different directions , namely the traffic flow coming from Soekarno Hatta street and Jl . Z.A Pagar Alam . The high volume of traffic that passes through the roundabout causing congestion or meeting a pretty solid vehicles from different directions, either from the direction of Jl . Soekarno Hatta and Jl . ZA Pagar Alam. When rush hour ( Peak hour ) congestion often occurs as a result of the convergence of traffic coming from Jl . Soekarno - Hatta towards Jl . Z.A Pagar Alam and vice versa . This is due to the large flow of traffic as a primary arterial road . Roundabouts generally have a better survival rate than other types of intersection control . The purpose of this study was to determine the Level of Service ( LoS ) , to evaluate the performance and the capacity to determine the feasibility of a roundabout. This type of research used in this study is a survey method . Because this study is an activity probe to obtain the facts - the facts of the symptoms that are known , seeking factual information and collect data to be evaluated by comparison. From the research value of the service level ( level of service ) tangle AB ( from Bakauheni to Tanjung Karang vice versa)is A, tangle BC (from Tanjung Karang to Kotabumi vice versa) is B , while the fabric of CA (from Kotabumi to Bakauheni vice versa) is E. greatest congestion on the fabric of CA ( from North to East and vice versa ) due to the tangle of capacity can not serve existing traffic volumes . Radin Inten countless roundabouts conditions worse because at the fabric of the value CA LOS ( level of service ) is E with a value of 0.9471 ratio ( 0.80 < V / C < 0.90 )

Keywords : levels of service , capacity of the roundabout , degree of saturation
