ANALISIS PENINGKATAN KINERJA DAN PERAMALAN USIA KINERJA SIMPANG 3 SULTAN ALAUDDIN-MONUMEN EMMY SAELAN DENGAN PENDEKATAN PKJI 2023 DAN VISSIM DI KOTA MAKASSAR

Sultan Alauddin-Monumen Emmy Saelan T-Junction is a non-signaled intersection in Makassar City which has a saturation degree of 0.97 and has problems in the form of frequent conflicts such as merging and crossing in the middle of the intersection which causes Makassar City Transportation Office officers to have to go to the field to regulate traffic. Therefore, this study aims to provide the best recommendations to related parties in terms of improving the performance of Sultan Alauddin-Monumen Emmy Saelan t-junction.
The recommendations proposed in this study are 3 recommendations using two approaches, namely PKJI 2023 and simulation using Vissim software with the GEH test method in determining the validation of the modeling. The best recommendation proposed in this study is recommendation III in the form of changing the type of intersection control to an APILL intersection with an early cut off on the Eastern approach and making geometric changes on the North approach (Jalan Monumen Emmy Saelan) with a width of 1 meter with the performance results obtained on Vissim obtained the average length of the intersection queue is 40.14 meters with an average intersection delay of 50.88 seconds. Based on the comparison of existing performance with the best recommendations, this intersection has experienced an increase in the degree of saturation indicator. As for the 6th year, the recommendations that have been proposed have experienced a decline in performance, so re-planning is needed for that year.
