Abstract
We propose and study new vehicular traffic flow models, incorporating the anticipation of the change in the car spacings ahead in the determination of the speed of the cars in each time step. Our models are based upon the Fukui and Ishibashi (FI) traffic flow model in which cars are allowed to move a maximum of M sites in each time step if spacing permits, together with a probabilistic delay for the cars moving at the maximum speed. By taking into account the anticipation in the change of car spacing due to movement of the car ahead, the present models give an enhanced traffic flux as compared to the FI model. The present models also give a fundamental diagram consisting of three phases - a feature consistent with traffic flow observations.
