摘要：

We study the traffic how in the hydrodynamic limit, where the analogy to fluid flow leads to the traffic equation in the form of the Navier-Stokes equation. It is shown that the traffic equation exhibits a variety of behaviors such as homogeneous how, turbulent behavior, and density waves with fluctuations in the appropriate regime. In particular, the stability against random fluctuations and the possibility of 1/f fluctuations in the traffic current are investigated.
