  • Leveraging Probe Data to Assess Security Checkpoint Wait Times
    Abstract: The process of travelling to an airport, passing through various processes, and ultimately departing the airport involves many activities. This paper focuses on using probe data obtained from phones with discoverable Bluetooth devices to sample the time it takes passengers to transit from the non-sterile to sterile side of an airport facility. To collect this data, the Kenton County Airport board partnered with Purdue University to conduct a study at the Cincinnati/Northern Kentucky International airport (CVG) over a 3 week study period, during the 2011 Thanksgiving holiday. Bluetooth Monitoring Stations (BMSs) were used to collect unique identifiers from approximately 46,000 unique devices and compute over 1.5 million travel time between 17 different BMSs. Using a Pareto distribution approach, hourly security wait times were ordered and a methodology was developed to identify periods where there might be opportunities to reduce wait times (relative to a specified maximum wait time) by opening more lanes as well as periods where there might be opportunities to reduce the number of lanes operating. Using this methodology, it was determined that only 5 hours during the study period had median wait times of greater than 20 minutes during the month of November in 2011. The paper concludes by discussing how this technique can be used to perform longitudinal comparisons between airports as additional airports begin automating the collection of checkpoint wait times.

    Submit a Discussion

    Attendees are welcome to submit a written discussion of any paper presented at the Annual Meeting. Written discussions will be considered for publication in the TRB Transportation Research Record series along with the paper being discussed. The author of the paper is given the opportunity to submit a written closure to the discussion. Please notify Rosa Allen at TRB by February 1, if you plan to submit a written discussion. When this notification is received, TRB staff will verify that the paper being discussed will be published and will provide the most recent version of the paper. This notification is therefore critical to ensure that all prepared discussions are used and to address issues in the most recent version of the paper in question.

    The discussion manuscript should be submitted to Rosa Allen by April 15 in electronic format as a Microsoft Word file (6.0 or later version). For the criteria used for discussions and for information on how to submit discussions for papers, see the Information for Authors document online at the TRB Annual Meeting website, under the Participant and Attendee Guides.
