Description
Summary:At the present early stage of application, automatic train driving systems still require constant supervision by the driver, and the continuous attention level of the driver is very important. This study investigated the changes in drivers' concentration' levels during the automatic driving of a high-speed EMU (electric multiple units) train, as well as the influence of their attention on take-over performance when necessary. It was found that the degree of concentration decreased over time, with the inattention degree ranging from 20% to 57%. Attention was weakly correlated to the take-over time and strongly correlated to the stable running time. When drivers inattention degree was controlled between 20% and 33%, their response speed to a take-over request might be improved, but inattention would affect their judgment of braking power after a take-over. When the inattention degree was over 33%, all take-over performances became worse.
