在这项调查中，8名空军空中交通管制员（ATC）在TRACON（终端雷达进近控制）上执行了三种场景，这是一种基于计算机的空中交通管制（ATC）模拟。我们使用了两个场景，每个场景都有三个难度级别。一种情况是通过操纵要处理的飞机数量来改变交通量，另一种情况是通过操纵到达和离开的飞行比率、飞行员技能和飞机类型的混合来改变交通量的复杂性。第三种情况是超载，要求受试者在有限的时间内处理更多的飞机。使用性能、主观（TLX）和生理（EEG、眨眼、心率、呼吸、扫视）测量来评估操作对控制者工作量的影响。难度水平对TRACON表现、TLX、眨眼、呼吸和脑电图测量均有显著的主要影响。只有脑电图与流量类型的主要影响有关。研究结果为复杂任务中各种工作负载度量的差异敏感性提供了支持，强调了交通复杂性在空管工作负载中的重要性，并支持TRACON作为空管工作负载研究工具的实用性。
In this investigation, eight Air Force air traffic controllers (ATCs) performed three scenarios on TRACON (Terminal Radar Approach Control), a computer-based air traffic control (ATC) simulation. Two scenarios were used each with three levels of difficulty. One scenario varied traffic volume by manipulating the number of aircraft to be handled and the second scenario varied traffic complexity by manipulating arriving to departing flight ratios, pilot skill and mixture of aircraft types. A third scenario, overload, required subjects to handle a larger number of aircraft in a limited amount of time. The effects of the manipulations on controller workload were assessed using performance, subjective (TLX), and physiological (EEG, eye blink, heart rate, respiration, saccade) measures. Significant main effects of difficulty level were found for TRACON performance, TLX, eye blink, respiration and EEG measures. Only the EEG was associated with main effects for the type of traffic. The results provide support for the differential sensitivity of a variety of workload measures in complex tasks, underscore the importance of traffic complexity in ATC workload, and support the utility of TRACON as a tool for studies of ATC workload.
