  1. Crowd Dynamics Simulation Research Dr. D. J. Kaup Dr. T. L. Clarke Rex Oleson Dr. Linda C. Malone University of Central Florida 3100 Technology Parkway Orlando, FL 32826

  2. Overview • Generalize Lakoba-Kaup- Finkelstein crowd simulation model to incorporate personality factors • Improved simulation of crowd behaviors in crowded environments.

  5. ( ) K K 1 ¡ ½ ½ 0 1 Density Dependent Panic Factors Added LKF Model Snapshot of a non-panicking crowd. Larger circles represent bodies, and smaller ones, noses, of pedestrians; in this way, the direction of motion of a pedestrian becomes apparent.

  6. Break Away Behavior Snapshot of a non-panicking crowd a few seconds after a group of pedestrians at the back of the crowd “breaks away".

  7. Exit Angle Results Based on NSF-funded Lakoba-Kaup-Finkelstein model Number of people exiting per 100 seconds

  8. Verification Using Crowd Video:Citrus Bowl Crowd: UCF-Tulane 2005
