Performance Analysis of Road Segment and Level Crossing (JPL) 340 KM 158+795 as Access to Adisutjipto International Airport of Yogyakarta

Abstract

Roads and rail tracks are land transportation infrastructures that play an essential role in supporting human activities both as passenger and goods transport. One of the problems of land transportation in Indonesia is a large number of level crossings between road and rail track. These level crossings are generally operated semi-automatically, and their operation significantly affects vehicle traffic on the road. This study not only aims to identify traffic parameters on the road and the completeness of the level crossing safety infrastructure but also to analyze the performance of the access road to the Adisutjipto International Airport of Yogyakarta, which intersects with the level crossing of the 340 KM 158+795 JPL. The results of the study showed that the traffic flow from the South to the North section was 1484.5 pcu/day, while from the South to the North section was 808.5 pcu/day. Moreover, the average traffic delay was 100.3 seconds with the longest vehicle queue length from the North to the South section was 118 m, while from the South to the North section was 48 m. Lastly, it was concluded that an increase in traffic density of 1 pcu/km would cause a decrease in vehicle speed by 0.1999 km/hour.
