XP-DITE - Checkpoint Design Integration and Evaluation

XP-DITE (Accelerated Checkpoint Design Integration Test and Evaluation) aims to develop and demonstrate a comprehensive, passenger-centred, outcome-focused, system-level approach to the design and evaluation of airport security checkpoints. This allows stakeholders to incorporate a wide range of requirements and to evaluate checkpoint performance against system-level security, cost, throughput, passenger satisfaction and ethical factors.

XP-DITE will develop a suite of design tools and evaluation methods to implement the XP-DITE approach. These will be validated through trials at two European airports: Schiphol Airport and Manchester Airport. Two key elements of the project are the design tool and the evaluation tool. The design tool allows the design of innovative new checkpoints and modification of existing checkpoints to meet combinations of overall system level requirements such as cost, throughput, customer service, security level and regulatory compliance, as well as ethical factors. The evaluation tool, called the Shared Evaluation Platform, comprises a validated set of protocols and tools for evaluating the performance of checkpoint design or operational system, again at the system level. The Shared Evaluation Platform will contain tools and methods for evaluating checkpoint designs on paper as well as tools and methods for evaluating the checkpoint once it has been built and put into operation.

XP-DITE outcomes

For airport operators and checkpoint designers, XP-DITE will provide a set of tools that will enable aviation security checkpoints to be designed and evaluated. It will enable all aspects of performance to be included. XP-DITE allows airports to optimise checkpoint designs to the individual needs of their business. For regulators, XP-DITE will explore new system-level approaches for the evaluation of checkpoint performance. The XP-DITE tools will allow regulators to carry out ‘what if’ experiments to explore the impact of new regulations, as well as the implications of new approaches and technologies developed by the industry. For the aviation security industry, XP-DITE will facilitate the introduction of new technologies and innovative products by enabling their effect on the overall performance of the checkpoint to be predicted and measured. For the travelling public, XP-DITE will result in fewer delays and improved convenience at the airport, whilst ensuring that they are kept safe.

Industry engagement

Throughout the project, the XP-DITE team will work closely with airport operators, regulators and other stakeholders, both to gather requirements and to disseminate the results of the work so that the European and international security community can benefit from the project. XP-DITE is aligned with the objectives of industry initiatives such as the IATA Checkpoint of the Future to improve passenger facilitation whilst maintaining required security levels. It is also aligned with the objectives of governmental activities such as US TSA’s Risk-Based Security and the UK DfT’s Outcome-Focused Risk-Based (OFRB) regulation initiative. XP-DITE is an enabler for these activities. It will provide the tools and methods needed for the design and evaluation of these new security checkpoint concepts.
