Members of CASRA recently published a study in the International Journal of Industrial Ergonomics on remote cabin baggage screening (RCBS) versus traditional screening at the lane, i.e. local cabin baggage screening (LCBS). The study used linear mixed models for analyzing threat image projection (TIP) data from 1706 screeners collected over two years (669’168 TIP events). The results showed better detection of prohibited articles (higher hit rate) and longer processing times in RCBS than in LCBS. In both settings, we found a decrease in the hit rate with increasing time on task, and this decrease was stronger when the task load was high. Interestingly, the effects of work setting, time on task, and task load were relatively small compared with the interindividual differences in performance across screeners. The published paper is available here.

The aim of the conference is to bring together psychologists from a variety of backgrounds to exchange their newest findings. CASRA members will present five different research studies on the topic of airport security.

CASRA will be participating in the IATA Cargo Security and Facilitation Forum 2019 in Amsterdam, Netherlands, on October 30 in Session 8: “Evolution of Screening Technology and the Human Factor Archetype”. In a panel discussion, we will contribute with a presentation on applied research which explores human-machine interaction and how this interaction will continue to shape the screening technology landscape. For more information please find the agenda here. We would be happy to meet you there as well.

In June 2019, the X-Ray Tutor (XRT3) was implemented in Manila at the Ninoy Aquino International Airport as well as at the Philippine Office for Transportation Security. Both cabin baggage and hold baggage screening modules were installed and now provide highly effective and efficient individually adaptive computer-based training to security officers in the Philippines.

In late June, CASRA participated in the IATA event “Air Transport Security – 2040 and beyond” at the EUROCONTROL headquarters in Brussels. The event consisted of plenary sessions and workshops for aviation security experts to exchange ideas and examine how air transport security will need to evolve over the next decades. IATA will consolidate the results of the workshops into a White Paper and publish it next September.

On May 14, 2019, CASRA participated in a meeting of The European Organisation for Security (EOS) to present an update on our research: The 14th ACBS Joint Operational Working Group Meeting provided a constructive platform for exchanging information on current issues, developments, and trends in advanced cabin baggage screening – mainly from the perspective of airports and manufacturers, but also regulators and researchers.

We are proud to announce that we have been awarded a contract by the regional governments of Münster and Düsseldorf. The contract resulted from a competitive procurement process for computer-based training. Four airports in Nordrhein-Westfalen will be training with our X-Ray Tutor, which is officially certified by the Federal Police of Germany. We are looking forward to a successful cooperation.

We are happy to announce our contribution to current research with a scientific paper called Expertise, Automation and Trust in X-Ray Screening of Cabin Baggage. It was recently published in the journal Frontiers in Psychology. This article focuses on how experts and novices performed in an X-ray baggage-screening task while being assisted by an adaptable diagnostic aid. Furthermore, it examined how both groups operated and trusted this automated system. For further information click here.

Three members of CASRA attended the 65th Spring Congress of the Gesellschaft für Arbeitswissenschaften (GfA) in Dresden, Germany and presented their research studies. The first presentation of CASRA had the title Airport security X-ray screening of hold baggage: 2D versus 3D imaging and evaluation of an on-screen alarm resolution protocol [Link]. The second presentation had the title X-ray screening of hold baggage: Are the same visual-cognitive abilities needed for 2D and 3D imaging? [Link]. The third presentation was named Examining Threat Image Projection Artifacts and Related Issues: A Rating Study [Link]

The results of the pilot study conducted by CASRA in cooperation with Member States of the ICAO Cooperative Aviation Security Program – Asia Pacific Region (CASP-AP) have been analyzed. They confirmed again that training with XRT3 significantly improves screeners’ detection performance (as measured with the X-Ray CAT) compared to no training and that this improvement already occurs after less than ten hours of training.

A study was recently published on detection measures for X-ray image inspection of cabin baggage conducted with 124 airport security officers (screeners). The detection performance measures d’, A’ and d_a with a slope parameter of 0.5 was compared and the outcome provided recommendations for scientific studies to ensure maximum validity of results. The paper was published in the prestigious journal Attention, Perception and Psychophysics and can be downloaded here.

CASRA is currently conducting a pilot study in cooperation with Member States of the ICAO Cooperative Aviation Security Program – Asia Pacific Region (CASP-AP). Participants from eight different countries are evaluating the benefit of the web-based CASRA Solution as a capacity-building tool regarding personnel selection, X-ray image recognition training, as well as competency assessment.

On December 12-13 2018, the EU-China Aviation Partnership Project (APP) held a workshop in Beijing on aviation security, focusing on the international standards implementation perspectives and introducing new technologies. During this workshop, CASRA had the opportunity to provide more information on the different training requirements for aviation security staff and to present different solutions, how those requirements can be met.

The Horizon 2020 project we are participating in since June this year – TRESSPASS – is now online. Please go to https://www.tresspass.eu/ to get information about the risk based border control concept and find a newsletter subscription link.

At the 2018 AVSEC World Day on October 1st 2018 in Athens, CASRA is invited to join a panel that discusses challenges of human factor in aviation security when introducing new technologies in screening processes. For further details on the program see here.

We are very pleased to announce that Geneva Airport has renewed its CASRA Solution licenses for another three years for use in its training and testing processes.

We at CASRA are very happy and proud to announce that we were awarded a contract by the Canadian Air Transport Security Authority (CATSA) resulting from a competitive procurement process in which we will be providing our brand new computer-based training and testing solution X-Ray Tutor 4 (XRT4) to all 89 Canadian designated airports. We are very much looking forward to a decade of fruitful cooperation with CATSA.

We are pleased to communicate the approval of the latest CASRA project “STA2RT” (Systematic Threat Assessment, New Standards, Learning Technology Research – Transfer into Practice). Besides the continuation and extension of the Systematic Threat Assessment, the project aims to investigate relevant questions in connection with the change to the latest technology – EDSCB C3 standard – in cabin baggage screening. Further the project will examine new learning technologies, for example virtual reality, whether they deliver added value to the screening in practice.

We are happy to announce our contribution to current research on automation in X-ray screening. A paper called “Automation in airport security X-ray screening of cabin baggage: Examining benefits and possible implementations of automated explosives detection” was published recently in the journal Applied Ergonomics. In this investigation, we examined the effect of automation aids on detecting explosives in passenger bags. For further information click here.

Starting in June 2018, CASRA will participate in a new project under Horizon 2020 called TRESSPASS: The robusT Risk basEd Screening and alert System for PASSengers. TRESSPASS aims to develop a harmonized concept for risk-based border management in Europe, and to show its validity by using pilots and methods like red teaming and computer simulations.

We are very pleased to announce that CASRA joined the IATA Strategic Partnership Program to build new relationships as well as strengthen existing partnerships with key industry stakeholders.

The Berlin airports Tegel and Schönefeld renewed their licenses for the X-Ray Tutor in order to continue training their security officers with the CASRA Solution software. We are very happy to prolong the collaboration with Berlin airports!

At the 2018 Counter Terrorism Symposium in Miami on January 23-24 2018, CASRA was invited to present a sociotechnical approach – based on a systematic threat assessment – for the development of countermeasures by enhancing the human factor. An edited version of the presentation is available here.

We are very pleased to announce that our training software X-Ray Tutor 3 (XRT3) has received the Official Recognition by the Federal Police in Germany for the use as training software for aviation security assistants (§ 5 LuftSiG) in the field of X-ray image analysis. XRT3 is available for different fields of operation, such as Cabin Baggage Screening, Hold Baggage Screening, Cargo Screening (§ 9 LuftSiG), Air/Airport Supply (§ 8 LuftSiG) and many more.
