Model Simulation of Holiday Session Traffic Flow at Three Ways Intersection in Indonesia

Key Points

At peak hour, traffic density leads to a degree of saturation of 0.776 and average delay of 13.075 seconds.
Projections for 5-10 years show expected saturation at 1.10 and delay of 25.234 seconds, indicating worsening conditions.
Modeling alternatives revealed that diverting north-south traffic to minor roads improves average speed to 23 km/h.
Effective traffic management is essential during holiday seasons to maintain level of service standards and reduce delays.

Abstract

Traffic density increases fluctuatively during holidays due to rising tourist activities, requiring seasonal traffic management. This study analyzes the impact using PKJI 2023 and PTV VISSIM modeling. At peak hour, the intersection shows a degree of saturation (DS) = 0.776 and average delay = 13.075 sec/MPH with LOS B. Projections for the next 5–10 years indicate DS = 1.10 and delay = 25.234 sec/MPH with LOS D. Of three modeled alternatives, the best is Alternative 2: diverting major north-south traffic to the east minor road, resulting in average speed = 23 km/h, delay = 14.075 sec/MP, queue length = 16.417 m, and LOS B.
