Abstract
The Pingit Intersection, a signalized junction in central Yogyakarta, faces increasing traffic volume and frequent congestion, connecting fourmajor roads: Jalan Magelang, Jalan Pangeran Diponegoro, Jalan Tentara Pelajar, and Jalan Kyai Mojo. This study evaluates its current performance and proposes improvement strategies based on PKJI 2023 standards and PTV Vissim traffic simulation. Data were collected through field surveys, including traffi volume, signal cycle time, intersection geometry, vehicle speed, driving behavior, queue length, and side frictions, supplemented by secondary data such as site maps and population figures. Improvement alternatives included adjusting the signal cycle time according to PKJI 2023, modifying signal phases into five phases, and enabling continuous left-turn movement on the southern approach. Existing conditions showed saturation degrees of 1.41 (North), 1.00 (East), 1.10 (South), and 1.01 (West), with queue lengths of 180 m, 155 m, 175 m, and 115 m respectively. The average delay reached 264.05 sec/pcu, corresponding to Level of Service (LOS) F. The most effective scenario was adjusting the cycle time to 130 seconds as per PKJI 2023, which produced uniform saturation degrees of 1.32 in all directions. Queue lengths increased slightly to 240 m (North), 220 m (East), 193 m (South), and 216 m (West), but average delay reduced to 252.64 sec/pcu, maintaining LOS F. Although congestion persisted, the modification demonstrated a modest performance improvement, providing a basis for further optimization strategies.
