Mikrosimulasi Kinerja Simpang Bersinyal Dengan Menggunakan Software Surrogate Safety Assessment Model (SSAM) di Kota Malang (Studi Kasus: Simpang Terusan Sulfat)

Abstract

Safety, speed, and capacity should be taken into account for designing intersection (AASHTO, 2001). Therefore, it is necessary to know the conflicts at the intersection. This experimental research aims (1) to find out the performance of Malang Sulfate Canal intersection, (2) to know the conflicts in it, and (3) to find the best recommendation. MKJI, PTV Vissim 10, and Surrogate Safety Assessment (SSAM) were used for data analysis. The result shows that the delay value at the peak hour was 54.4 seconds with an E service level category. The conflicts at the highest peak hours were 2782 conflicts (2035 crossing conflicts and 747 lane-change conflicts). At the end, widening the road reduced the number of traffic conflict by 26% and the delay value by 2%.
