• Abstract:
  The two-dimensional traffic model of Biham, Middleton and Levine (Phys. Rev. A, 1992) is ; a simple cellular automaton that exhibits a wide range of complex behavior. It consists of both ; northbound and eastbound cars traveling on a rectangular array of cells, each cell equipped ; with a traffic signal. The traffic signals switch synchronously from allowing northbound flow ; to eastbound flow. By gating individual traffic signals, i.e. allowing individual traffic signals ; to break from synchrony in predetermined, deterministic scenarios based on the local state of ; traffic, the range for which the system self-organizes into a state of unimpeded flow is extended. ; On a 100x100 cell array, this additional intelligence enables accomodation of 200 cars more ; than the original BML model, without any reduction in average velocity.
