Extended First-Come First-Served Scheduler for Airport Surface Operation

This paper describes the extended first-come first-served scheduler that is being developed for integrated departure and arrival management at airports. The previously developed scheduler with route assignment capability has been enhanced to handle actual wake turbulence separation requirements at runways instead of simple departure and arrival rate constraints. The scheduler is tested with recorded surface traffic data gathered for three days in April 2015 at Incheon International Airport. Three prioritization strategies of nominal, arrival, and partial arrival priorities, are compared. Both the arrival and partial arrival priorities decrease overall delays with significant reduction in arrival delays. The adverse impacts on departure delay are minimal.
