Examination on Corner Shape for Reducing Mental Stress by Pedestrian Appearing from Blind Spot of Intersection

Abstract

This paper 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. 30 college students as the participants were experienced the unlimited long virtual passage where the intersections would be appearing regularly and continuously, through a head mounted display. The width of the passage was set at two sizes, 1,600 mm and 2,000 mm. The 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. 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 worry-free passage design.
