ANALISIS PENGENDALIAN SIMPANG APILL GUNA MENINGKATKAN KINERJA SIMPANG BERSINYAL DI KOTA YOGYAKARTA (STUDI KASUS : SIMPANG BERSINYAL SGM)

Simpang 4 SGM is one of the intersections that has a high volume because it is an access point to the city area that brings together the traffic flow from the Jalan Kenari section, the Veteran Street section, and the Jalan Kusumanegara section with the longest queue length of 145 meters. Research The data used is data on intersection geometry, traffic flow for 24 hours on weekdays and intersection cycle time. This research aims to realize optimal performance of Simpang SGM by conducting engineering design using PKJI 2023.
The results of the study found that the existing performance in each plan has not been optimal because the degree of saturation exceeds 0.85 so it needs to be optimized. The results after optimization with PKJI 2023 were obtained that improvements were needed that could be made by resetting the cycle time and the green time was completely lost so as to get a new plan planning . The increase in performance is evident from the decrease in queue length and delays.
