Outline of Final Research Achievements

The authors aim to propose the design of a bicycle and pedestrian track that reduces pedestrians’ dangerous sensations through virtual space. This paper, as a preliminary experiment, investigates subjects’ dangerous sensations putting on a head mount display (HMD) on the condition that the running speed of a bicycle and interval distance between a bicycle and a pedestrian are different when they are passing each other in the HMD and examines the factors affecting the dangerous sensations of subjects by using logistics regression analysis the data of which is the result of the investigation.

Academic Significance and Societal Importance of the Research Achievements

実験の動画映像およびVR映像の実験結果を用いて変数選択法の変数減少法によるロジスティック回帰分析を実施した結果，論理性および説明力の観点から自転車歩行者道上において走行自転車とすれ違う歩行者の危険感知の予測モデルの適合性は良好であった．VR映像による予測式から走行自転車と前方ですれ違う場合には，すれ違う間隔が1.4m以上，後方からの場合には，すれ違う間隔が1.7m以上であれば，危険を感知する歩行者は少ないことが示された．
