We study the evolutionary dynamics of a mobility system in which agents are able to explore the environment and to communicate between them in order to increase the efficiency of the system, i.e. to minimize the average time needed to reach their goal, choosing the quickest path and avoiding the formation of traffic jams. The agents use an evolvable pheromone-like indirect communication system,...

Problem of traffic jams is common in large cities. Urban traffic control systems aim to solve this problem. The major difficulty in urban traffic is large number of variables for representing the state of traffc, such as traffic flow,speed, and density. Lack of precise relations between these variables is another problem. In this paper, we present a new model for traffic flow and introduce a tr...

An emergent behavior is a global, qualitatively novel system behavior, which results from the interaction of the system’s components, is maintained for a specific period of time, and ceases to exist when particular components are removed from the system. The formation of a complex snow-flake patterns, the buildup of a traffic jams, the erection of termite cathedrals, the development of troubles...

The recent loss of lives and traffic jams (Figure 1) for tens of miles as hurricanes Rita and Katrina approached the Gulf coast demonstrate the enormous difficulty in evacuating urban areas [6]. Besides hurricanes, evacuation may be necessary due to other potential disasters, e.g., fire, terrorism, and nuclear or chemical plant accidents. Thus, the local emergency management community engages i...

– Motivated by an analogy with traffic, we simulate two species of particles ('vehicles'), moving stochastically in opposite directions on a two-lane ring road. Each species prefers one lane over the other, controlled by a parameter 0 ≤ b ≤ 1 such that b = 0 corresponds to random lane choice and b = 1 to perfect 'laning'. We find that the system displays one large cluster ('jam') whose size inc...

The recently suggested correspondence between domain dynamics of traffic models and the asymmetric chipping model is reviewed. It is observed that in many cases traffic domains perform the two characteristic dynamical processes of the chipping model, namely chipping and diffusion. This correspondence indicates that jamming in traffic models in which all dynamical rates are non-deterministic tak...

Current challenges in sustainable water resources management have created demand for integrated, flexible and easy to use environmental simulation models which are able to simulate the quantitative and qualitative aspects of the hydrological cycle with a sufficient degree of certainty. Along with these models various accompanying applications are needed in order to support the setup, applicatio...
