How Much Is Enough?: Sizing the Deployment of Baggage Screening Equipment by Considering the Economic Cost of Passenger Delays

Abstract : We begin by giving some background on the problem we are addressing, including a summary of our prior work in this area and what we recommended to the government in March 2002. We then describe our findings from this work, connecting it to the prior work and pointing toward a new set of recommendations. We lead the reader through the steps of the analysis, starting with how we calculated the various baggage-scanning delays, how those delays were translated into passengers choosing to arrive at the airports earlier than otherwise necessary, and how that behavior is ultimately reflected in additional cost to the nation's economy. This briefing is relatively long because a number of important sensitivities need to be addressed.
