The Optimization Model of Kenthungan Intersection
Wahyu Widodo

Universitas Muhammadiyah Yogyakarta


The closures of the intersections because of construction, particularly in an urban area, are potentially impact on the congestion on the other road networks. The intersection which under construction in Yogyakarta city is the Kenthungan junction that located in North Ring Road of Yogyakarta. This study aims to create the optimization model of an existing junction condition (without project) and junction condition in the future (with project) to minimize the traffic impact. The software that used in this study was PTV. VISSIM 9.0 which is one of the micro simulation programs invented by PTV Group with the model results in the form of dynamic simulation. It could be concluded that the model result on existing conditions produce the level of service (LOS) E with the delay of 721.85 sec/passenger car unit (> 60 sec/pcu). Furthermore, the impact of the construction on this intersection caused the increasing of delay at other intersections, those are Kenthungan (771.71 sec/pcu), Gejayan (from 669.53 sec/pcu to 719.69 sec/pcu), and Monjali (from 591.67 sec/pcu to 641.11 sec/pcu). Therefore, it was recommended to widen the highway lane to become 2 m and the vehicle driver suggested avoid to passing the kenthungan intersection and choose another routes, i.e Southern Ring Road, especially for heavy vehicle in order to reduce traffic impact.
