Analisis kinerja bukaan median dan kinerja ruas jalan pada Jalan Pangeran Antasari Kota Samarinda

Abstract

Pangeran Antasari Street has a u-turn which leads to Siradj Salman Street. Because of the u-turn, there was a quite long queue and vehicle speed reduction. The purposes of this research were to find the performance of the u-turn, the performance of the road segment, and the alternatives which expected to increase the effectiveness u-turn and road segement. The analysis method referred to the 1997’s MKJI and the median opening evaluation from PPPB 06/BM/2005. Then the traffic modeling was conducted in VISSIM software. The result of the research was the existing u-turn performance in the north-to-south direction had a queue and time delay of 17,28 meters and 12,08 seconds. In comparison, the south-to-north direction had a 24,59 meters queue and 9,86 seconds time delay. The existing road segment performance in the north-to-south direction had a mean speed of 28,33 km/hour, while the south-to-north direction has a mean velocity of 29,78 km/hour. The best alternative was moving the median opening 100 meters north and adding a new median opening 100 meters apart from the previous median. From the alternative, an increase of 68,60% in the mean velocity, 98,49% in the queue, and 91,85% in time delay are seen in the north-to-south direction. Meanwhile, the south-to-north direction had an increase of 48,72% in the mean velocity, 72,65% in the queue, and 73,25% in the time delay.
