| Title: | Traffic-flow cellular automaton: order parameter and its conjugated field |
| Authors: | Souza, André Maurício Conceição de Vilar, L. C. Q. |

| Abstract: | We use a cellular automaton traffic model in order to study a nonequilibrium phase transition. We define an order parameter and show that its conjugated field is a parameter of randomness of the model. We analyze the symmetries of the free (unbroken) and of the jammed (broken) phases. Our results are consistent with a second-order phase transition at p=0. Nontrivial critical exponents have also been obtained. |
