Human Factors and Air Traffic Control

We contribute to the study of human factors and the impact that those factors have on the safety of different transportation modes. Our research on human factors focuses on the relationship between human behavior and transportation safety, and on the importance of the interactions between people and systems. Transportation systems that take into account what people can do and what their limitations are help to reduce the probability of human error. Human error remains the most important contributing factor in aviation accidents and incidents, and we continue to support the growing body of knowledge on human factors in this area, especially those affecting air traffic controllers. A key component in an air traffic controller's work is a display screen. Our researchers have conducted a study on the use of color in air traffic displays, and have developed guidelines for this area. The guidelines are based on what is known about human vision and display capabilities, and on the knowledge gained from the use of color in the cockpit and Air Traffic Control environment as well as human factors best practices.
