Abstract
It is observed that the fluctuation of a traffic current on an expressway obeys
the 1/f law for low spectral frequencies. Under proper assumptions the
variation of the car concentration is expressed by the Burgers nonlinear
differential equation. The observed power spectrum is accounted for
as a characteristic feature of the Burgers turbulence.
