Self-Organized Control of Irregular or Perturbed Network Traffic
Dirk Helbing, Stefan Lämmer, Jean-Patrick Lebacque
We present a fluid-dynamic model for the simulation of urban traffic networks with road sections of different lengths and capacities. The model allows one to efficiently simulate t…
Understanding widely scattered traffic flows, the capacity drop, platoons, and times-to-collision as effects of variance-driven time gaps
Martin Treiber, Arne Kesting, Dirk Helbing
We investigate the adaptation of the time headways in car-following models as a function of the local velocity variance, which is a measure of the inhomogeneity of traffic flow. We…
Analytical investigation of oscillations in intersecting flows of pedestrian and vehicle traffic
Dirk Helbing, Rui Jiang, Martin Treiber
In two intersecting many-particle streams, one can often find the emergence of oscillatory patterns. Here, we investigate the interaction of pedestrians with vehicles, when they tr…
How individuals learn to take turns: Emergence of alternating cooperation in a congestion game and the prisoner's dilemma
Dirk Helbing, Martin Schonhof, Hans-Ulrich Stark +1
In many social dilemmas, individuals tend to generate a situation with low payoffs instead of a system optimum ("tragedy of the commons"). Is the routing of traffic a similar probl…
Inefficient emergent oscillations in intersecting driven many-particle flows
Rui Jiang, Dirk Helbing, Pradyumn Kumar Shukla +1
Oscillatory flow patterns have been observed in many different driven many-particle systems. The conventional assumption is that the reason for emergent oscillations in opposing fl…
Analytical Investigation of Innovation Dynamics Considering Stochasticity in the Evaluation of Fitness
Dirk Helbing, Martin Treiber, Nicole J. Saam
We investigate a selection-mutation model for the dynamics of technological innovation,a special case of reaction-diffusion equations. Although mutations are assumed to increase th…
