摘要: A thermodynamic theory is formulated to describe the phase transition and critical phenomenon in traffic flow. Based on two-velocity difference model, time-dependent Ginzburg—Landau (TDGL) equation under certain condition derived flow near point through nonlinear analytical method. The corresponding two solutions, uniform kink are given. coexisting curve, spinodal line obtained by first second derivatives of potential. modified Korteweg de Vries (mKdV) around using reductive perturbation method its kink—antikink solution also obtained. relation between TDGL mKdV shown. simulation result consistent with result.
