Abstract
We show that the Car Following Model with Optimal Velocity (Optimal Velocity Model), whicl~w as proposed in our previous paper, is a successful traliic model in reproducing the characteristic features of observed traffic flow data.In our model the transition from free flow to congested flow occurs spontaneously by the collective motion of vehides, wl~ich obey to tl~e same dynamical equation.Tl~e observed specific discrepancy of traffic flow vs-car density grapl~is well understood in terms of tl~e phase transition in our model.1.
