Several simulations were done in the past that simulates pedestrian motion. Some of these are:

- Bird flocking (Reynolds, 1987)
- Motion of artificial fish (Tu and Terzopoulos, 1994)
- Gaskinetic fluids (Henderson, 1971)
- Cellular Automata (Blue and Adler, 2000)
- Modified Cellular Automata model (Toyama, 2006)
- Floor field-and-Agent based Simulation Tool (Kretz, 2007)
