A new approach to air traffic controller workload measurement and modelling

Abstract: Purpose -The purpose of this paper is to develop an analytical approach for workload measurement based on the task times and the changing task priorities of en route air traffic controllers (EATC). Design/methodology/approach -A model called Total Airspace Workload Measurement Model was developed to measure EATC workload. Turkish airspace was chosen for practical application of the model. A survey was conducted of EATC to calculate the weighting coefficients and times of different tasks defined in the model. T… Show more

“… where w, N, T and C signify the weighting coefficient of each task, number of aircraft, task time and weighting factor of subtask, respectively; k, l and h also represent the set of indices of subtask. The details of the ATCW measurement equation are defined in the study of Oktal and Yaman (2011).…”

“…Many workload calculation methods have been proposed in previous studies based on dependent variables: physical activity [45], physiological indicators [46][47][48], simulation models of the controller's tasks [34,35,[49][50][51][52], and subjective ratings [53,54]. Gianazza [55] have reviewed literature about workload prediction and compared several machine learning methods on the problem of learning workload prediction models from historical data.…”

“…Task load calculation model designed by Oktal and Yaman [52] considered three kinds of task load, the monitoring task load, the conflict task load and the coordination task load. The monitoring and the conflict task loads occur inside the sector while the coordination task load between the sector and its adjacent sector.…”

“…The research focusing on the controller workload has been carried out by a desire to balance the task load, understand occupational stress, eliminate operational errors, enhance safety and improve throughput. Many workload calculation methods have been proposed in previous studies based on dependent variables: Physical activity [57], physiological indicators [58,59,60], simulation models of the controller’s tasks [46,47,61,62,63,64] and subjective ratings [65,66]. Gianazza [67] have reviewed literature about workload prediction and compared several machine learning methods on the problem of learning workload prediction models from historical data.…”
