Degree distribution of the visibility graphs mapped from fractional Brownian motions and multifractal random walks
Xiao-Hui Ni, Zhi-Qiang Jiang, Wei-Xing Zhou
The dynamics of a complex system is usually recorded in the form of time series, which can be studied through its visibility graph from a complex network perspective. We investigat…
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…
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…
Derivation of a Fundamental Diagram for Urban Traffic Flow
Dirk Helbing
Despite the importance of urban traffic flows, there are only a few theoretical approaches to determine fundamental relationships between macroscopic traffic variables such as the…
"Bubbles in Society": The Example of the United States Apollo Program
Monika Gisler, Didier Sornette
We present an analysis of the economic, political and social factors that underlay the Apollo program, one of the most exceptional and costly projects ever undertaken by the United…
On the Controversy around Daganzo's Requiem for and Aw-Rascle's Resurrection of Second-Order Traffic Flow Models
Dirk Helbing, Anders Johansson
Daganzo's criticisms of second-order fluid approximations of traffic flow [C. Daganzo, Transpn. Res. B. 29, 277-286 (1995)] and Aw and Rascle's proposal how to overcome them [A. Aw…
