Abstract

Abstract:

To investigate the effects of dispatching mode and ranking pressure on the mental workload of mining truck drivers, 24 drivers participated in driving simulation experiments with EEG monitoring. EEG power spectrum integrals, subjective workload scores, and driving performance indicators were analyzed under different task conditions. The results showed that switching from the "binding mode" to the "dispatch mode", particularly with ranking pressure, significantly increased drivers' cognitive demand and effort. The "binding mode" resulted in higher average speeds and fewer braking events, whereas the "dispatch mode" provided faster responses and greater flexibility in unexpected tasks. EEG results indicated that the "dispatch mode" alone maintained mental workload at a moderate level, while its combination with ranking pressure produced a significant synergistic effect, leading to mental workload overload.

Key words: intelligent dispatching patterns, ranking pressure, mining truck driver, mental workload, electroencephalography(EEG)
