In this study, we will quantitatively clarify the actual condition of straying behavior in multiple facilities with different plans using three-dimensional laser sensor, verify the hypothesis, and clarify the environmental factors of straying behavior. Expressway rest area Ebina SA(up/down) and Fujieda PA(up) are selected as research object having two types of plans. As the result, Spatial range of visual perception of restrooms and its signage are important factor for confirmation and distinction.
