CROSSES – “CROwd Simulation System for Emergency Situations”

CROSSES – “CROwd Simulation System for Emergency Situations”

Period: January 2000 - June 2003 Type: European Research Status: Completed


When confronted to emergency situations, the reactions of people are generally difficult to control and the emergency plans elaborated in advance may be inefficient. There is therefore a need to be prepared and trained to limit this problem.

CROSSES intends to demonstrate the use of a simulator recreating a situation realistic enough so that training can be efficiently performed through virtual reality.
This will result in work being carried out in:

  • Providing efficient tools to perform the ‘real’ reconstruction of an actual urban environment.
  • Providing a methodology and a set of tools for the simulation of a realistic, dynamically evolving, virtual population (crowd) living in this city environment.
  • Mixing sound and graphical visualisation for a real immersive simulation.
  • Integrating coherently all the data in a way the complete reconstructed environment remains exploitable in a real-time simulation system.

MIRALab’s contribution

MIRALab’s role in the project is to implement the tool for generation of the virtual crowd and animate them in the virtual world.
