The update rules of velocity of a car depend not only on the positions of this car and the car ahead of it, but also on the velocities of the two cars. Using computer simulations obtain some basic qualitative results and the fundamental diagram of the proposed model. In comparison with those of the existing models in the literature, find that the fundamental diagram of the proposed model is more consistent with the results measured in the real traffic, and the model is able to reproduce some relevant macroscopic states that are found in the real traffic flow but cannot be predicted by the existing models.

Model Description

Chinese {{currentDetailLanguage}} Chinese

Quoted from: https://journals.aps.org/pre/pdf/10.1103/PhysRevE.64.066128 Li X, Wu Q, Jiang R. Cellular automaton model considering the velocity effect of a car on the successive car[J]. Physical Review E, 2001, 64(6): 066128.

In the following we introduce the proposed model under the same condition as the two basic models. The notation is also similar. At each discrete time step t→t11, the velocity of the ith car is updated according to the following rules:

where V(i11,t11) 8 is an imaginary velocity of the (i11)th car at the (t11) time step, given as
