“…Programs such as TSA PreCheck [5] and Schiphol Privium [6] allow frequent travellers to undergo a reduced and therefore faster security check. TSA PreCheck claims theoretical throughput benefits of up to a factor two, although they have not been confirmed by empirical tests [7,8].…”

Airport security checkpoints are the most important bottleneck in airport operations, but few studies aim to empirically understand them better. In this work we address this lack of data-driven quantitative analysis and insights about the security checkpoint process. To this end, we followed a total of 2277 passengers through the security checkpoint process at Rotterdam The Hague Airport (RTM), and published detailed timing data about their journey through the process. This dataset is unique in scientific literature, and can aid future researchers in the modelling and analysis of the security checkpoint. Our analysis showed important differences between six identified passenger types. Business passengers were found to be the fastest group, while passengers with reduced mobility (PRM) and families were the slowest two groups. We also identified events that hindered the performance of the security checkpoint, in which groups of passengers had to wait long for security employees or other passengers. A total of 335 such events occurred, with an average of 2.3 passengers affected per event. It was found that a passenger that had a high luggage drop time was followed by an event in 27% of the cases, which was the most frequent cause. To mitigate this waiting time of subsequent passengers in the security checkpoint process, we performed an experiment with a so-called service lane. This lane was used to process passengers that are expected to be slow, while the remaining lanes processed the other passengers. It was found that the mean throughput of the service lane setups was higher than the average throughput of the standard lanes, making it a promising setup to investigate further.

Since September 11, 2001, the United States has invested a significant amount of resources into improving aviation security operations, with the Transportation Security Administration (TSA) assuming the responsibilities for security policy-making at commercial airports. This paper reviews the literature that supports policies for risk-based passenger screening procedures and chronicles the analytical analysis leading up to the launch (in October 2011) of the TSA Precheck program, as a first step toward implementing a risk-based security strategy for passenger and baggage screening. Multi-level passenger prescreening is the basis of the A c c e p t e d M a n u s c r i p t mathematical framework behind TSA Precheck; the framework provides a prescriptive control of security operations in settings with limited resources. TSA Precheck assigns each passenger to a risk group, based on the initial perceived risk level (assessed in the prescreening stage), and then calibrates the security measures to mitigate the risk associated with each group. With passengers arriving in real-time and the order of their arrivals uncertain, the resource utilization problem is solved by dynamic programming. A numerical comparison between a risk-based and an equal-risk (i.e., non-risk-based) security model is presented to quantify the benefits of risk-based security.

“…A special supporting infrastructure is needed to perform the clearance tasks. The term "layered security" also known as a "Swiss Cheese" model, addresses the security doctrine [16], [25], [78], [81] and its practical realization as a multi-state model [35], [59]. The idea of layered security is to distribute available resources (such as organizational topology, surveillance network, security personnel and service machines) in an optimal way in order to expedite traveler screening and service performance.…”

“…In [39], the design goal is to minimize risks that "all the holes of a "Swiss Cheese" model do not line up". Some efforts to improve the performance of layered security have been reported with respect to: 1) topology of the waiting queuing lines [53] and checkpoint flow models [52]; 2) optimization of the passenger flows [64], [89]; 3) development of security measures [16], [78], including measures of the cost of travel time variability [24]; 4) cost-efficient minimization of security layers [77]; 5) modeling and simulation using a multi-state model of service [59], analytic hierarchy model [92] and hybrid models; for example, combining analytic hierarchy model and others, such as Dempster-Shafer [6], and Bayesian [58]; 6) traveler authentication and risk assessment, in particular, using multi-metric causal models [50], [91]; and cognitive agent models [45].…”

“…Misidentification remains a common occurrence due to shortcomings in current watchlist technologies and provides the principal motivation for this paper. Contemporary checkpoint is a cyber-physical computational platform that includes traveler authentication [23], [29], [48] using e-passport/ID [5], watchlist screening [9], [51], [86], concealed object detection [32], [60], interviewing [1], [4], [61], and risk assessment [49], [74], [76], [78], [91] under umbrella of justice and privacy issues [10], [15], [19]. In the International Air Transport Association (IATA) roadmap [36], four pillars of the checkpoint of the future are identified: computation intelligence, operations, infrastructure, and economic measures.…”
