VRシステム，交差点，心理・生理ストレス，皮膚電気活動(EDA)
This thesis investigates the effective minimum size for cutting out the edge of the intersection for reducing the mental stress of the pedestrian appearing from an intersection, by the experiment using the electrodermal activity measuring method and the virtual reality technology. 15 college students participated with this experiment. One result is that the mental stress for the crossing pedestrian could be reduce by applying a cutting out of more than 1,000 mm to the corner of the intersection. The other result that the mental stress can be more significantly reduced by applying cutting out of more than 2,000 mm. According to these results, it was suggested that cutting out the corner of the intersection of about 1,000 mm would give a certain effect on the safe passage design.
