GUIDANCE EFFECT OF ROAD NETWORK BY THE GUIDE SIGN INFORMATIONS PRINTED IN THE DRIVING MAP

为了使用道路引导标志中显示的地名，驾驶员应该使用描述了引导标志信息的驾驶地图预先研究他的路线和地名之间的关系。此外，与地图配合使用的路标的积极使用（例如使用该地图中描述的路标信息选择路线）成为可能。本研究从这样的角度出发，通过模拟器的室内实验分析了使用该地图进行预先研究的效果。结果表明，通过事先使用地图的研究，地名信息的使用增加了，能够运行预定路线的驾驶员的比例提高了，驾驶员在预定路线上运行的距离增加了，驾驶员的心理负荷也减少了。

Driver should study beforehand the relation between his route and the place names using a driving map where the information of guide sign is described, in order to use the place names that are displayed in the road guide signs. Moreover, the positive use of the guide sign cooperated with the map, for example the selection of routes using the guide sign information described in this map, becomes possible.In this research, from such a viewpoint, the effect of the beforehand study using this map was analyzed by the indoor experiment with a simulator. As a result, it became clear that the use of information of place names increased by the beforehand study using the map, the ratio of the drivers who ccould run their scheduled routes improved, the distance which the drivers run in their scheduled routes increased, and also that the psychological load of drivers was reduced.
