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 in traffic light system, the existing car-following equation is improved and a traffic flow model considering signal influence is proposed. The numerical results show that the model can well reproduce the aggregation and dissipation of traffic flow, It is proved that the model is reasonable and effective by starting the wave evolution and propagation characteristics.
