  • Cellular automata make up a class of completely discrete dynamical systems, which have became a core subject in the sciences of complexity due to their conceptual simplicity, easiness of implementation for computer simulation, and their ability to exhibit a wide variety of amazingly complex behavior. The feature of simplicity behind complexity of cellular automata has attracted the researchers' attention from a wide range of divergent fields of study of science, which extend from the exact disciplines of mathematical physics up to the social ones, and beyond....

  • Modelling and simulation are disciplines of major importance for science and engineering. There is no science without models, and simulation has nowadays become a very useful tool, sometimes unavoidable, for development of both science and engineering. The main attractive feature of cellular automata is that, in spite of their conceptual simplicity which allows an easiness of implementation for computer simulation, as a detailed and complete mathematical analysis in principle, they are able to exhibit a wide variety of amazingly complex behaviour....

  • The need to keep in touch—we all have it, whether for business or personal reasons. Now you can keep in touch on the way to work or the shopping center, from a construction site or the golf course, or in a rental car or on your boat. If you spend time away from your best communication tool—the telephone—a cellular phone can add several business hours to your week. Now you can stay in touch with your office, your customers, or your family, even as you inch along in a traffic jam. And cellular’s excellent audio performance ensures clear voice reception....

  • Three distinct sequential cellular responses characterise the reaction of the adult spinal cord and brain to injury. An acute haemorrhagic phase immediately ensues after wounding, in which haematogenous cells flood the lesion site. This is followed by a subacute period during which macrophages clear necrotic debris, glial cell reactions are mobilised, the clot becomes organised, and scarring is initiated. Finally, the scar tissue contracts during a consolidation phase .

  • In this project, traffic simulation according to the cellular automaton of the Nagel-Schreckenberg model (1992) with different boundary conditions. The sudden occurrence of traffic jams is successfully realised as well as boundary induced phases and phase transitions are observed in the Asymmetric Simple Exclusion Process. The extension to the Velocity Dependent Randomization model leads to metastabile high flow states and hysteresis of the flow. The impact of speed limits on the probability of the formation of traffic jams is investigated.

  • Road traffic microsimulations based on the individual motion of all the involved vehicles are now recognized as an important tool to describe, understand, and manage road traffic. Cellular automata (CA) are very efficient way to implement vehicle motion. CA is a methodology that uses a discrete space to represent the state of each element of a domain, and this state can be changed according to a transition rule.

  • The purpose of this study was to estimate travel time under incident conditions on a freeway. This paper presents a cellular automaton model that mimics traffic conditions and estimates travel times from upstream locations through the incident bottleneck, given an estimate of the incident duration.

  • We study a simple three-lane cellular automaton, based upon the well known NagelSchreckenberg model, and examine the effect of slow cars in such a system. We point out the important parameters defining the shape of the fundamental digram for the three-lane model and compare it to that of a two-lane one, showing the new mode of interactions between lanes. It is possible to reduce the influence of slow cars by choosing an adequate version of the symmetry with respect to lanes.
