PERFORMANCE EVALUATION OF THE UNSIGNED INTERMEDIATION OF THE FOUR RH-MART

Evaluasi Kinerja Simpang Tak Bersinyal Pada Simpang Empat Rh-Mart

Abstract

Road intersections are places where traffic conflicts occur. The volume of traffic that the road network can accommodate is determined by the intersection capacity of the road network. This study aims to determine the magnitude of the intersection capacity, degree of saturation, delay and queuing opportunities at the RH-Mart Namlea City intersection, whether the solution or alternative solution to the traffic jam problem at the RH-Mart Namlea City intersection. This research was conducted at the unmarked intersection in the city of Namlea, especially the RH-Mart intersection. The intersection performance analysis includes capacity (C), degree of saturation (DS), delay (D); and the probability of queuing QP% 'was calculated using the MKJI 1997 method. The results showed that the intersection capacity (C) = 632.30 pcu / hour, the degree of saturation, for all directions at the intersection arm and for all survey days Ds <0.75, namely on working days obtained Ds = 0.071 and 0.083, for short days Ds = 0.087 and 0.068, and on holidays Ds = 0.068 and 0.070. it means that there is no need for improvement of the intersection geometry, control of total intersection currents, and control of the flow with signs to maintain the desired degree of saturation (DS ≤ 0.75). Because the Ds value obtained is very small there are no delays and queuing opportunities that occur.
