Abstract

Closely spaced signalized intersections can generate recurring queues, delays, multiple stops, and spillback, particularly along corridors experiencing increasing traffic demand. This condition occurs at the Gunaksa and Jumpai Intersections on the Prof. Dr. Ida Bagus Mantra Road corridor in Klungkung Regency. This study aimed to develop, calibrate, and validate a PTV VISSIM microsimulation model, assess existing intersection performance, and evaluate an alternative interintersection signal coordination scheme. A quantitative descriptive-evaluative approach was applied using geometric data, traffic volume, vehicle composition, speed, and signal timing data. Existing intersection performance was assessed using the Indonesian Road Capacity Guidelines (Pedoman Kapasitas Jalan Indonesia [PKJI]) 2023 and PTV VISSIM. The model was calibrated using driving behavior parameters and validated using an independent-samples t-test. Signal coordination alternatives were developed by adjusting cycle length, phase sequence, green time, and offset values based on time–distance diagrams.The existing service levels were classified as Level of Service E at Jumpai Intersection and Level of Service F at Gunaksa Intersection. Signal coordination generally reduced queue length, vehicle delay, stopped delay, and fuel consumption across all observed peak periods, with the most consistent improvements occurring at Gunaksa Intersection. The largest recorded reductions were 24.85% in queue length, 24.53% in vehicle delay, 26.53% in stopped delay, and 20.90% in fuel consumption. Signal coordination improved corridor performance, although its effectiveness varied depending on peak periods and traffic flow characteristics.
