다국어 초록 (Multilingual Abstract)

The subject of this research work is to study the driver's vision and eye-movement characteristics under the different conditions of road, traffic and driving. The analysis of this investigation was conducted spatially or temporaly into three parts; eye-mark distribution, viewing-time percentage and fixation duration.
It was found that eye mark distribution depend on the driving condition and road condition, with a certain tendency in the centralization. For horizontal observation, the distributions were symmetrical in general, and the axes slipped left word for specific driving more than for free driving. the vertical observations were almost the same in both cases.
Viewing-time percent depends mainly on the condition of driving, free or specific. in the general, the road surface and preceding vehicle categories have in the highest ratios.
Fixation duration clarify that the driver is momentarily watching the signs or singals or road or preceding vehicle several time (2.5, 6.3, 2.5, 6.3 times on average) in oder to get their message.
