Temporal Patterns Underlying Domestic Departure Passengers Behavior in the Airport

Abstract

Air travelers' behavior is closely related to the operational performance of any airport terminal. Much of previous research has focused on how airport operators balance the number of facilities in a terminal and the Level of Service (LOS), while the behavior of passengers is less considered. Not much is known, however, about passenger's behavior during the entire departure process in an airport. In this study, we analyze empirical departure passenger's data to gain an insight into the regular patterns of their activities in an airport. We find that there exist two distinguished temporal patterns during two discretionary periods-post check-in and pre-security check, post security check and pre-boarding. The time that departure passengers spend in these two periods is well approximated by a double power-law distribution and an exponential truncated power-law distribution respectively. The two distinguished distributions suggest that there may be different mechanisms underlying passengers' behavior as indicated by previous studies on human mobility. We introduce a stochastic model that considers traveling experience and time pressure to capture the decision dynamics of human behavior. Simulation results suggest that traveling experience and time pressure dominate passenger's decisions before and after security respectively. Our findings contribute to a better understanding of human dynamics, and also offer the potential for optimizing and simulation of airport terminal operation.

Estimating the Lag Time Between Flight Arrivals and Parking Exit Volumes at a Major Airport: A Practical Approach

“…Another way is considering the behavior of passengers, and developing simulation models to predict their activities, like [18], [19], and [20]. More recently, Wang et al presented a stochastic model for capturing the decision dynamics of domestic departure passengers, where travel experience and time pressure are considered [21]. Although simulation models can achieve a high level of accuracy and show the distribution of passenger flows, it is costly to tune and adopt them in practice.…”

An Optimized Deep Learning Approach for Improving Airline Services

“…Passenger satisfaction is influenced by airport facilities and services [1]. As demand increases, demand for high-quality air services also increases [2]. In the current competitive environment, airlines must satisfy passengers' needs by introducing distinguished services to outperform their competitors and gain a competitive advantage [3].…”
