The University of Birmingham used eye tracking to examine how different operators perform road traffic control tasks and make decisions based on noisy data streams from various sensing technologies and historical data.
Data moves fast in a road traffic control room. How do the operators that keep our streets and highways flowing smoothly process complex information coming from multiple sources simultaneously? Researchers at the University of Birmingham used wearable eye trackers from Tobii Pro to assess the decision-making strategies of traffic control operators as they managed an 'object in the road' task. The results clearly illustrate the value of eye tracking in human factors assessments.
Eye tracking allowed the researchers to directly measure and analyze visual information sampling behavior in the field study. This information is crucial in a road traffic control room because the situational awareness of operators can be deceptive and based on familiarity effects. Eye tracking offers a means of studying and adapting user interfaces to better support more accurate and efficient operator performance.
We chose Tobii Glasses 1 for field studies in control rooms because of its portability, ease of wear, and ease of use.
