          <datacite:description descriptionType="Other">大規模なイベント会場で実際に行われた分散退場を評価する方法を提案する．分散退場とは，群集混雑を未然に避けるために一部のエリアの観客に時間差で帰るよう指示する取り組みである．分散退場の効果を実証実験により検証することは難しく，その効果は明らかになっていない．本研究では，データ同化を用いて群集シミュレータ上で実際に分散退場が行われた状況を再現し，再現したシミュレーションから分散退場の要素を取り除くことにより，分散退場の効果を比較可能にする．実験では野球観戦イベントを対象に，計測で得られた観客の退場開始時間を群集シミュレータに入力し，各試合の分散退場の評価を行う．実際に行われた分散退場と分散退場を行わない一斉退場をシミュレーションした結果から，分散退場の効果の有無や特性，改善点などについて考察し，分散退場の指針を示す．</datacite:description>
          <datacite:description descriptionType="Other">We propose a way to evaluate instructions for visitors to exit at different times according to different blocks of seats at a large-scale event. The demonstration experiments implementation is difficult to that can verify the instructions at a large-scale event. This study evaluates the situations with and without the instruction after improving the crowd simulation similarity with reality using data assimilation. The experiments use the data measured at some baseball matches which applied the instructions. Then, We indicate a policy considering the effects, characteristics, and improvements of the instructions from evaluating results with and without the instructions.</datacite:description>
