Abstract: Runway occupancy time (ROT) is a critical factor determining runway operational efficiency and ensuring safe aircraft landing and expeditious runway vacation. This study analyzes the impact of rapid exit taxiways (RETs) on runway occupancy time (ROT) using operational data from Incheon International Airport's Runway 2 and Runway 4. Analysis of 17,181 landings reveals that Runway 4, equipped with four optimally positioned RETs, achieved an average ROT of 59.7 seconds—a 19% reduction compared to Runway 2. Notably, Class C aircraft showed a 23.7% reduction, primarily driven by the high utilization of RETs positioned at 1,600m and 1,900m. These findings empirically support the installation of additional RETs on Runway 2 and the planned Runway 5, demonstrating that optimizing RET placement is essential for enhancing overall runway capacity and operational efficiency.
