本文提出了一种耦合地图跟车交通模型，该模型描述了一群道路车辆在单车道上行驶而不超车的动态行为。该模型由前车和后车组成，具有分段线性最优速度函数。当领头车速度变化时，我们可以观察到车群中出现交通拥堵。我们推导出模型中永远不会发生交通拥堵的条件。此外，为了抑制交通拥堵，对于每辆车，我们使用[Konishi、Hirai 和 Kokame，Phys. Rev. E 58, 3055 (1998)]，并提供了设计控制器的系统程序。 [S1063-651X(99)12410-3]。
This paper proposes a coupled map car-following traffic model, which describes a dynamical behavior of a group of road vehicles running in a single lane without overtaking. This model consists of a lead vehicle and following vehicles, which have a piecewise linear optimal velocity function. When the lead-vehicle speed is varied, we can observe a traffic jam in the group of the vehicles. We derive a condition under which the traffic jam never occurs in our model. Furthermore, in order to suppress the traffic jam, for each vehicle we use a dynamic version of decentralized delayed-feedback control proposed in [Konishi, Hirai, and Kokame, Phys. Rev. E 58, 3055 (1998)], and provide a systematic procedure for designing the controller. [S1063-651X(99)12410-3].
