Peak Hour Crowds: How 30,000 People Move in an Hour

Present the crowd evacuation after a night performance in a floor plan: thirty thousand people simultaneously pour out of the viewing area. The floor plan uses arrows of different thicknesses and colors to indicate main flow directions, and marks four bottleneck points—two bridges, one corner, and an exit gate. The plan uses color blocks to indicate crowd density in each section, and notes the clear width and hourly throughput of each main passage. Design countermeasures are also indicated: widening bridge decks, chamfering corners, phased release at the end of the performance, and an emergency evacuation path normally closed. Technical drawing style.
Avoid: Drawing as a perspective view, no indication of bottlenecks and widths, crowd flow represented by a single arrow, omitting evacuation countermeasures.

以平面圖的方式呈現一場夜間演出結束後的人流疏散:三萬人同時從觀賞區湧出,平面圖以不同粗細與顏色的箭頭標示主要流向,並標出四個瓶頸點——兩座橋、一個轉角與出口閘門。圖上以色塊標示每個區段的人流密度,並註明各主要通道的淨寬與每小時通過量。設計對策一併標示:橋面加寬、轉角截角、演出結束時分段放行、以及一條平時關閉的緊急疏散路徑。技術圖面風格。避免:畫成透視圖、沒有標示瓶頸與寬度、人流用單一箭頭表示、省略疏散對策。
