Abstract
Nowadays, traffic accident in our country make rapid increase. The causes of an accident increase are vehicle increase and delay of a safe countermeasure. Attentiveness of a driver is important in order not to cause an accident. Therefore, it is important to investigate a visual performance at an automobile operation. A visual mentality of a driver at high-speed running becomes more unusual in comparison with a state of general road running. A purpose of this research is to analyze objectively visual phenomenon on high-speed running.
A eye movement of a driver on expressway running was measured by a record with eye-mark camera. A subject are ran with the next 3 kinds of a method. They are going straight with law speed, going straight with acceleration and lane change (passing). Considering a skill of a subject and safety the condition of an operation was set up. Therefore, a condition is comparatively simple. From an experimental result, an obvious difference was observed on a fixation point distribution pattern. By analyzing a measurement data, characteristics on each conditions were extracted. And, significance of fixation time was examined by a analysis of variance.
From an experimental result, we reviewed the relation between a fixation point and the narrowness of the visual field range. A result showed that 0.3s fixation points had a significant characteristic. Further, a result suggested a correlation of a distribution of an eye-movement velocity with a fixation point. A conclusion that an eye-movement velocity changed by driving condition was obtained.
