摘　　要：利用枕木流动的速度感来估计列车运行速度已是司机的习惯做法。在列车低速运行时 ,这种速度感比从速度表上读数更具直接性。但正如人们长时间看到快速移动的物体会感到眼睛疲惫一样 ,在高速列车上司机长时间注视快速流动的枕木会引起视觉上的疲劳或眩晕。It is a usual way for drivers to estimate the speed of a locomotive by the sense of speed on coming sleepers. While a locomotive runs at a low speed, this sense is more directly perceived than that from reading the speedometer. But as looking at objects moving at high speed may cause eyestrain, in the cab of high speed locomotive, concentrating on fast moving sleepers for a long time may also lead to visual fatigue or dizziness. This paper discusses how to evaluate driver's sense of speed and avoid visual fatigue.
