PENGARUH GEOMETRI DAN KONFIGURASI SINYAL TERHADAP KINERJA SIMPANG DENGAN PENDEKATAN PKJI 2023 DAN PTV VISSIM (Studi Kasus : Simpang Tugu Wisnu Di Kota Surakarta)

Traffic congestion is one of the problems that greatly affects the service performance of a road. The effect of signal geometry and configuration on performance improvement at the Intersection can be influenced by an arrangement of Phase Sequence Signaling Devices (APILL), where the performance of traffic conditions and traffic at an intersection as well as improper settings will result in conflict points that have the potential to cause accidents. . One of the signalized intersections that needs to improve its performance in Surakarta City is the Tugu Wisnu Intersection.
The Tugu Wisnu Intersection has a 2023 PKJI queue length, an average DS value of 2.27, the longest queue length of 427.03 m, and an average delay of 232.4473 sec/pcu. The DS value has exceeded 0.85, meaning it needs to improve performance. This study aims to improve the performance of intersections using the PKJI 2023 and PTV Vissim methods. To test the validation used in the vissim simulation, namely driving behavior with traffic volume parameters tested using the GEH test. The planning results compared to the existing conditions obtained DS 0.84 with a cycle time of 213 seconds, queues were reduced by 50%, delays were reduced by 40% and tail queue remnants were reduced at the monument in the middle of the intersection.
