AI can get better over time and learn from operators.

AI can analyze an image in under 0.2 seconds.

These aspects that make the job difficult for humans, can be easily carried out by AI: Some airports analyzed by BNA experienced a turnover of 30-80 per cent across five years.

They’ll also be more likely to quit their job. Decreased motivation can have a detrimental impact on their screening ability, given that screeners who are not motivated might miss threats. These aspects of the job can have a demotivating effect on screeners, who can suffer from emotional exhaustion, low job satisfaction, and a lack of motivation. Motivation (or lack thereof) can impact performance. Screeners have roughly 2.5 seconds to observe the inside contents before the bag is fully in view, after which another bag might immediately begin to appear. Operators only have a few seconds to make a decision From: Meuter, Renata & Lacherez, Philippe (2015). 3: Exponential performance decline with increasing time. During busy periods, operators might be screening for much longer than expected. Research shows that the performance of an X-ray screener starts to suffer after only 10 minutes, and that performance declines exponentially with increasing time. The life of a security screening officer can be demanding and incredibly tiring. Mental fatigue dramatically worsens performance over time

Research indicates that the more items a human has to look for, the more time they need to look for those objects, and as a consequence, rare items have higher miss rates (like firearms and ammunition). Even an additional monitor on a dual-view machine can increase the operator’s reaction time and inadvertently lead them to miss items.Ī long and growing prohibited items list makes screening complexĭuring the hectic screening process, operators are looking for dozens, if not hundreds, of potential items on the prohibited items list. Noise, slow-downs, temperature, screen reflection, and air quality can all affect screener performance. Though X-ray screening is a task that requires dedicated focus, many factors in the busy and noisy checkpoint environment can distract operators. What makes this screening process so prone to failure? We’ll look through some of the contributing human factors, and then discuss how artificial intelligence (AI) can revolutionize checkpoint security. The screening task can be draining and monotonous because it is both repetitive and constrained by the limitations of the human perceptual system. These limitations “ could potentially be exploited by terrorists or criminals seeking to attack the aviation system”. Security screening plays a critical role in securing airports, relying heavily on human perception, judgment, attention, and decision-making.
