Studi Pengaruh Perlintasan Sebidang Jalan dengan Rel Kereta Api Terhadap Karakteristik Lalu LIntas (Studi Kasus: Perlintasan Kereta Api Jalan Hj. Ani Idrus)

Abstract

Crossing a plot of roads with railroads is a potential point of traffic delays. The railway crossing affects road users such as air pollution, noise, increased vehicle operating costs and greater travel times. In this study will evaluate the characteristics of traffic, delays, and queues that occur when the door is closed. The location of the research is the crossing of the Hj road railway. Ani Idrus / Pandu Road East Medan District Medan City North Sumatra. This rail road is single track with safety door. Data collection is done during rush hour like morning which start at 06.30 Wib s / d 08.30 Wib with interval time 15 minutes. Vehicles are grouped into 3 type light vehicles, heavy vehicles and motorcycles. The equivalent value of passenger cars is calculated according to the Indonesian Road Capacity Manual (MKJI) February 1997. The relationship between volume, speed and density is approximated by GR Wells1969 model), Green shields is then selected best as input for queue analysis and delay with shock wave methods. From the calculation of queue and delay using the shock wave method when the door is closed the queue condition and the maximum delay occurs at 17.11 wib which produces the release time ta = 1.09 seconds, recovery time required tb = 97 seconds, with 32 meter queue length, The vehicle stops at maximum N = 138.5 smp has a delay time of 117 seconds, with Indicator E.
