From Crowd Dynamics to Crowd Safety: A Video-Based Analysis
Anders Johansson, Dirk Helbing, Habib Z. Al-Abideen +1
The study of crowd dynamics is interesting because of the various self-organization phenomena resulting from the interactions of many pedestrians, which may improve or obstruct the…
Specification of the social force pedestrian model by evolutionary adjustment to video tracking data
Anders Johansson, Dirk Helbing, Pradyumn Shukla
Based on suitable video recordings of interactive pedestrian motion and improved tracking software, we apply an evolutionary optimization algorithm to determine optimal parameter s…
Analytical and Numerical Investigation of Ant Behavior Under Crowded Conditions
Karsten Peters, Anders Johansson, Audrey Dussutour +1
Swarm intelligence is widely recognized as a powerful paradigm of self-organized optimization, with numerous examples of successful applications in distributed artificial intellige…
Approximate Hamiltonian Statistics in One-dimensional Driven Dissipative Many-Particle Systems
Martin Treiber, Dirk Helbing
This contribution presents a derivation of the steady-state distribution of velocities and distances of driven particles on a onedimensional periodic ring. We will compare two diff…
Analytical Calculation of Critical Perturbation Amplitudes and Critical Densities by Non-Linear Stability Analysis of a Simple Traffic Flow Model
Dirk Helbing, Mehdi Moussaid
Driven many-particle systems with nonlinear interactions are known to often display multi-stability, i.e. depending on the respective initial condition, there may be different outc…
A Power Law for the Duration of High-Flow States in Heterogeneous Traffic Flows
Dirk Helbing, Benno Tilch
We study the duration of "high-flow states" in freeway traffic, defined as the time periods for which traffic flows exceed a given flow threshold. Our empirical data are surprising…
