Читать книгу People Flow in Buildings - Marja-Liisa Siikonen - Страница 21

Some buildings can have occasional population where people, for example, attend some event or lecture. Such buildings as stadiums, theatres, tall school or university buildings and the like provide seats or desks for the people. In these types of buildings the design population corresponds to the number of seats. In a stadium, the audience enters the building at the beginning of an event, or exits the stadium after the event. The average people flow is the capacity of the stadium within the time people are allowed to enter or exit the space. The peak traffic in schools can be estimated from the number of students in classroom and the duration of a break. Often students have to switch classrooms during a break, and the maximum flow can be estimated from these figures. If the next lecture is on another floor, the students have to switch floors, which creates sudden vertical traffic peaks.

Similar building tenants are observation decks and restaurants where people visit for an average period. There, the average people flow is obtained from the capacity of the space, and the duration of the visit. For observation decks, the traffic is two‐way. The same amount of people enter and exit the observation deck.
