基于信号灯交通系统中跟车行为的特点,改进了现有跟车方程,提出一个考虑信号影响的交通流模型。数值计算结果表明,该模型可以很好地再现车流的聚集与消散、停车波和启动波的演化规律及传播特性,证明模型是合理有效的。
Based on the characteristics of car-following behavior in a road traffic system containing signal light, we improve the car-following equation and then present a traffic flow model which considers the signal light influence. Numerical results show that the model can reproduce such phenomena as flow clustering and dissipating, and capture the propagation of stopping and starting waves. It is concluded that the model proposed in this paper is reasonable.
