Outline of Final Research Achievements |
We found that almost all Wi-Fi connection signals originate from human dynamics. Fluctuations in the number of signals that do not correspond to human dynamics originate from the transmission characteristics of Wi-Fi connection signals from human-owned network terminals. We also studied the possibility of a new method to correlate air (atmospheric) environment and human dynamics over a wider area (mesoscale) based on the estimated population using air monitoring data at measuring stations and cell phone base station information, and found that this method is effective over a mesoscale of 500 m and can be used in combination with human dynamics This method is expected to be effective on a mesoscale of 500 m, and to be used in combination with human dynamic monitoring that observes up to 100 m or more to study the relationship between human dynamics and the atmospheric environment on a wide range of scales.

Academic Significance and Societal Importance of the Research Achievements |
本研究は「人間が別の人間の環境リスク源になる」という喫煙の特徴に着目し,それを定量的に評価しうる「環境・人間動態モニタ」の開発が目的である。「人から人へのリスク」は昨今急激に懸念が増したエアロゾル感染にも共通し,新しい観点でのリスク評価の重要性も増している。測定局の大気モニタリングデータと携帯電話基地局情報を利用した推定人口と100m超まで観測する人間動態モニタをシームレスに運用することで,幅広いスケールの人間動態と大気環境の関係を検討できる可能性が示された。
