model and theory
What is inside a simulation software and how do you know if the results are reliable? Here is an overview.
Simulation model
Patterns of movement behavior are identified through observations, experiments, etc. (e.g. Jülich Research Center).
The computer models are validated on the basis of tests and comparison with real data. The ISO-Norm standardizes model test internationally. More information on validation.
These patterns are evaluated and translated into models that describe different levels of movement .
The characteristics of the different levels of behavior are translated into algorithms and the computer models are calibrated.

Congestion assessment and fundamental diagram
Congestion assessment according to DIN 18009-2
When many people need to exit a building quickly, it can cause congestion. This increases the time it takes for people to get to safety. People flow simulations are a useful tool to simulate such situations in the planning phase. But what exactly is a traffic jam? What criteria define it? And how should the results be evaluated?
More informationThe basis: the fundamental diagram
The basis of the congestion evaluation is the fundamental diagram. This describes the formation of congestion. In microscopic analyses, the fundamental diagram is used to calibrate the programs.
