Phys. Rev. E 52, 4664–4668 (1995)1/f noise in a two-lane highway traffic modelReceived 6 July 1995; published in the issue dated November 1995 A cellular automaton model of traffic current on a two-lane highway is proposed. Clustering and hopping mechanisms are introduced into the interactions between individual cars by the traffic rules. The power spectrum of the traffic current may show good 1/f behavior in certain parameter regions. The 1/f noise is the result of many-body interactions of clustering and hopping. It is found that a state with 1/f noise has a remarkable advantage allowing effective transporting. © 1995 The American Physical Society URL:
