PENENTUAN BIAYA KEMACETAN LALU LINTAS PADA SIMPANG BERSINYAL SGM YOGYAKARTA

What is it about?

The SGM signalized intersection in the city of Yogyakarta is a junction with high traffic volume and has the potential to cause traffic congestion. This study aims to analyze the performance of this intersections and estimate costs due to congestion that occurs. This study was performed by conducting a field survey to determine the geometric conditions, traffic volume, cycle time, and vehicle speed. The data obtained are then analyzed and modeled using Vissim 10 software. The intersection performance indicator considered is the queue length and level of service. The calculation of congestion costs using indicators of vehicle numbers, vehicle operating costs, spot speed, desired speed, travel time value, and queue time.

Why is it important?

The results of the observation showed that the performance of the SGM signalized intersection in Yogyakarta was very poor, with the level of service F at peak hours, so that repairs need to be done. In this study, the recommended solution consists of 2 alternatives, namely alternative 1, by changing the phase, and alternative 2, by widening the road. The results of the analysis show that alternative 2 provides the best solution to improve performance and reduce congestion costs at the intersection.
