<p>Runway and taxiway configuration could affect airport capacity
and safety, and airline taxiing time and fuel consumption. In this study, a
discrete-event stochastic simulation model is created to explore the impact of
four different runway and taxiway choices on a fictional airport with parallel
runways that have End-Around Taxiways (EAT) at each end.
Scenario 1 represent the conventional runway and taxiway choices used in
parallel runway systems, while Scenarios 2, 3, and 4 mimic three new choices
that become possible because of the usage of the EAT. Three designed
experiments are used to explore the influence of the four scenarios in terms of
taxi time, fuel consumption, and number of runway crossings during high traffic
periods, as well as the ability to cope with increases in the load level. </p>
<p>Some main findings are: 1)
using the outboard runway to land and the EAT as the taxi-in path would yield
the shortest average taxi-out time, while the average taxi-in time is similar
or longer than that in the conventional choice; 2) if arrival aircraft are
allowed to land over an active EAT, using the outboard runway to take off and
the EAT as the taxi-out path would show advantages in both the average taxi-in
time and the average taxi-out time; 3) if the EAT is operated under current FAA
regulation, using the outboard runway to take off and the EAT as the taxi-out
path could still show advantages in the average taxi-in time, while the average
taxi-out time is the longest during high arrival period; 4) the results of the
average fuel consumption indicate similar trends with the results of the
average taxi time; 5) using the EATs could either eliminate the number of
runway crossings or reduce it significantly; 6) the taxi times with the use of
EATs are more stable against the increases in the load level in comparison with
the conventional choice.</p>
<p>Safety and human factor issues related to allowing arrival
aircraft to land over an active EAT are discussed, as well as some future
research topics. This study may encourage airport operators and researchers to
explore how to make full use of existing EATs. This study, along with future
cost-benefit analyses based on the results of this research, would be a
valuable reference for airports that consider constructing EATs in the future. </p>
