Abstract | |||||||||
| In this paper, we numerically study energy dissipation caused by traffic in the Nagel-Schreckenberg (NaSch) model with open boundary conditions (OBC). Numerical results show that there is a nonvanishing energy dissipation rate Ed, and no true free-flow phase exists in the deterministic and nondeterministic NaSch models with OBC. In the deterministic case, there is a critical value of the extinction rate $\beta{cd}$ below which Ed increases with increasing $\beta$, but above which Ed abruptly decreases in the case of the speed limit vmax>2. However, when vmax. Comment: 8 figures | |||||||||
