Outline of Final Research Achievements

We conducted analysis and experiments to understand the characteristics of PMV traffic accidents and the sense of danger felt by pedestrians from PMVs.
Analyzing the characteristics of the accident with an electric wheelchair similar to PMV, it was found that a dangerous traffic accident was encountered "when driving on a road for cars" and "when driving on an unstable place such as a railroad crossing".
Comparing the median values of heart rate variability data, the narrower the distance, the higher the danger level. Hearing data analysis revealed that there were significantly more people at risk when the separation was 0.3 m and the PMV speed was 12 km/h.

Academic Significance and Societal Importance of the Research Achievements

日本国内において公道走行が認められていないPMVに関する事故危険性や、他交通参加者がPMVから受ける危険感の分析は多くは行われていなかった。特に危険感については、心拍変動データから求めたストレス値・危険感との関係は不明な部分も多く、その点において特色のある研究となっている。本研究では、調査対象が20～30代の男性のみであり追加分析が望まれるが、得られた成果は、今後、国内におけるPMV走行方法や走行環境を検討していくにあたり活用されることが期待される。
