Abstract
The objective of this study is to verify the hypothesis that cognitive process of railway drivers would be influenced by train speed. The hypothesis is tested by investigating railway drivers' cognitive processes at different speeds of a locomotion. The experiment shows that human performance of railway drivers decreases as the train speed becomes faster. In addition, simple signals outperformed complex signals at every train speed. Therefore, it is suggested to redesign complex signals simpler for improving drivers' human performance. It is also recommended that the Korean railway safety law should be revised to mention requirement of the signal design, especially for the fastest train including KTX. The implications of the experiments are discussed in detail.
