Computersimulation für Brandschutz und Fußgängerverkehr


Flow direction: Unknown

Boundary conditions: Open

Places of research: Russia/USSR

Underlying data: Field inquiries and experimental research

Data collection: Two different methods

1st method: Observation on location

  • To simultaneously gather data of the concentration and velocity a section of a footpath was determined (see graphic below).
  • An observer stood at the end of the section.
  • After the observer had marked a person in the crowd, he registered his arrival at the beginning of the section.
  • At this moment he began the time measurement and started to count the people passing him.
  • When the marked person arrived at his position the observer stopped the time measurement and the count.
  • As a result one got the number of people in a measured area, hence the medial concentration, and the time of movement through a measured area, hence the medial velocity.

2nd method: Observation of photographs

  • A characteristic section of a footpath was photographed from an elavated position and the measurements of the section were recorded.
  • The photographs were taken in regular intervals (3...5 s).
  • On the series of photographs a marked person was observed.
  • By counting the people in the measured area the medial concentration was obtained for each photograph and for the course of time of a marked person passing the section.
  • By observing the location of a marked person and the time he needed for passing the section the medial velocity was obtained.
