建物に付属する光によって与えられる路上での安心感:　岐阜県白川村の平瀬地区を対象として

摘要

This research investigated how lights attached to buildings in the street affected the sense of safety experienced by pedestrians. The street used for the experiment was in Hirase District, Shirakawa Village, Gifu Pref. As a result of the experiment, it was found that a sense of safety on the street was provided by lights in the building openings, and this safety zone extended to a range of about 1/2 of the maximum distance at which the lights were visible. Next, experimental lighting environments taking advantage of lights attached to buildings were produced within a range of 250m on the street. As a result of the experiment, it was found that residents tended to evaluate the sense of safety and the harmony with the landscape highly when there were lights in the openings or porches those had already been set up. On the other hand, tourists tended to evaluate the items highly when there were paper lanterns those were newly set up attached to the building facades or on the sides of buildings.%本研究の目的は、夜間の住宅街において、建物開口部から漏れている光や玄関灯などの建物に付属している光が、歩行者にどの程度の安心感を与え、また景観としてふさわしいかについて調査することである。住宅の内部空間や建物周辺の光が外部から認知される状態は、その建物に人が居るということを街路上の歩行者などに対して表すことにつながっている。
