Impact of Speedometer Forms on Integration Task Performance for Train Driving

Accurate speed control can effectively improve the efficiency of train operation. The advantages and disadvantages of the speed display form directly impact the interaction efficiency and the driver’s correct situational awareness of the train running state. Three kinds of train speedometer forms were designed, and the existing interface was compared with the three types. 28 subjects were selected to carry out four speed control experiments. The results showed that, the response time and accuracy performance were the highest in the case of color highlighting; the response time performance was higher but the accuracy performance was the lowest in the case of graph without numbers; the accuracy was higher but the response time was the lowest in the case of scale sparsity. This study shows that the speed display design should be give priority to color highlighting, while weighting the influences of number highlighting and scale sparsity.
