本論文では, 複数のレーザレンジスキャナを用いた歩行者トラッキングの方法, 及び駅での検証実験について述べる.提案手法は, ネットワークを利用して複数のレーザスキャナを同期させ, 得られた足断面のレンジデータから歩行者トラッキングを行う.トラッキングアルゴリズムは次の機能で構成される: レンジデータのクラスタリングによる足候補の検出, 足候補のグルーピングによる歩行者候補の検出, 歩行者候補の動きベクトル検出, 歩行モデルに基づく拡張カルマンフィルタによる既存軌跡の延長処理.提案手法を東京都内の駅構内コンコースに適用した結果, 最大で約150人を同時にトラッキングすることができた.トラッキング精度は, 通勤ラッシュ時において8割を超えた.広範囲における高密度の群集計測への応用が期待される.

The first building height limitation in Chicago was enacted in 1893. This paper is to review the process in enacting the limitation, from its drafts to the enacted limitation, and Chicago's own social context that enabled lawmakers to enact such a limit. Specifically, this paper is to focus on: 1) what urban problems were arising from the boom of "skyscrapers," 2) who took part in a series of discussion in conjunction with building height controls, for what intentions they agitated the matter, and whose intentions were brought into the enacted limitation, 3) what influence the limitation caused to the city and whether the lawmakers' intentions were realized.

Field survey on thermal environment and questionnaire survey were conducted over three seasons at three train stations, and thermal comfort was quantitatively evaluated. Moreover, usage patterns and passengers' attitude towards the station environment were investigated in order to comprehensively identify the thermal environment required for train stations. Environmental control of the entire station by air-conditioning would not be energy efficient due to its open structure, and task-ambient air-conditioning strategy is proposed.
