仮想空間を利用した河川周辺街路の経路選択行動特性に関する研究

Abstract

The purpose of this study is to utilize a 3-D virtual reality space to clarify how the presence of a river within an urban space might influence pedestrian wayfinding behavior. Firstly, in creating a 3-D virtual reality experiment system, we studied the operability of the interface for movement and line-of-sight direction displacement within the space. Next, we conducted the same experiments on the pedestrian wayfinding behavior of both the real space of the existing urban district under study and a 3-D virtual space re-created from this real space, and compared the results. To understand how the river space influences pedestrian wayfinding behavior, we then conducted a comparative experiment on the presence or absence of river space in identical streets, using the 3-D virtual space. The results reveal that when a river is present, many people actively try to utilize information about the river, for example by choosing to take a route along the river. In addition, even for people who use routes away from the river, the presence of river spaces serves to provide some clues to their location. Thus, river spaces function as a standard point of reference in the memorization of routes.
