ACRP Graduate Student Paper - Simulation Analyses of End-Around Taxiway Operations under Four Different Runway and Taxiway Choices

There are end-around taxiways (EAT) at four major U.S. airports to increase safety and throughput of parallel runway systems. This paper proposes two new runway and taxiway choices that become possible because of end-around taxiways. Instead of using the inboard runway to take off, the departing aircraft could use the outboard runway and use the end-around taxiway as the taxi-out path. A discrete-event stochastic simulation model simulates the operations of four different runway and taxiway choices. Two experiments compare the performance of the four choices in terms of average taxi times, average fuel consumptions per taxi, and number of runway crossings. In general, the results indicate that using the outboard runway to take off and the EAT as a taxi-out path would yield benefits in both taxi-in and taxi-out performance, as well as enhance runway safety. Using the outboard runway to land and the EAT as a taxi-in path would yield benefit in taxi-out performance and runway safety at the expense of a longer taxi-in time. Concerns related to using the EAT as the taxi-out path, as well as potential future research topics, are discussed.
