Information about Java Applets

The following subpages should show the user how pedestrian movement is  influenced by different parameters in different geometries. The subpages are divided in different sections:

• Introduction about the model
• Basic principles of the model
• Parameters of the model
• Applets for various geometries

The applets are CA (Cellular Automata) models and available for the following geometries:

• Corridor with periodic boundary conditions and bottleneck
  • The particles move through a corridor with periodic boundary conditions. In the middle of the corridor lies a bottleneck with variable width.
• Evacuation of a room
  • The evacuation of a room with no internal structure (i.e. a ballroom) through a single door. The velocity profile can be seen as well as all other fields. The problem of conflicts and friction between pedestrians can be investigated through the friction parameter pfric.
• Running through a room
  • Particles enter the room by a certain variable probability and leave the room through a door at the middle of the top wall.

Note: If you want to look at these applets please ensure that JAVA is enabled at your browser. In the near future we plan to present some more applets.
