Noise properties in the Nagel-Schreckenberg traffic model.
The jamming transition in the stochastic traffic cellular automaton model of Nagel and Schreckenberg is examined. The behavior of the power spectrum is analyzed. Numerical results are presented. Satisfactory analytical approximations are established in both low frequency and high frequency regions. The intrinsic traffic states are revealed in the middle frequency range. A signature of 1/f noise is observed at the critical density of the transition.
