基于智能交通诱导信息,提出一种改进的耦合映射跟驰模型,用于描述单车道的交通流动力学特性及其拥堵控制.利用反馈控制理论,给出了在头车速度发生变化时交通流保持稳定的条件.分析结果表明,考虑前方更多车辆的信息对交通流有致稳作用,亦即稳定性条件明显减弱.数值模拟证实了理论分析的正确性,通过与他人相关工作的比较得知,考虑智能交通诱导信息能够更有效地抑制交通拥堵. Based on the information of intelligent traffic guidance, an improved coupled mapping and following model is proposed to describe the characteristics of single-lane traffic flow and its congestion control.Using the feedback control theory, the traffic flow is maintained when the speed of the first vehicle changes The results show that considering the information of more vehicles in front, the stability of the traffic flow is stable, that is, the stability conditions are obviously weakened.Numerical simulation confirms the correctness of the theoretical analysis. By comparing with other related work, Considering that intelligent traffic-induced information can more effectively curb traffic congestion.
