Specifically , we present a full velocity difference ( fvd ) car - following model , a cellular automata ( ca ) model that considers the velocity effect of the preceding car , another ca model that can describe the synchronized flow , and a speed gradient ( sg ) macroscopic model which can describe the anisotropic properties of traffic flow
具体地说，我们提出了一种全速度差车辆跟驰模型，一种考虑前车速度效应的元胞自动机模型，另一种能较好模拟同步流的元胞自动机模型，以及一种能体现交通流各向异性特征的速度梯度宏观连续模型。
