摘要
城市交通网络中的十字路口是冲突交通流汇聚的节点,安全问题十分突出,黄灯在交通信号系统中起着非常重要的作用。在力学和运动学原理的基础上,提出保守黄灯时间的数学模型,并在此基础上对模型进行逐步修正,最后建立有效黄灯时间的数学模型,将该模型与实际情况进行拟合,可使其合理性得到验证。
Crossing roads are the nodes of conflicted traffic flow in urban traffic,where the safety problem is getting serious. Yellow light plays a very important role in traffic signal system. On the basis of the theory of mechanics and kinematics,mathematical model of conservative yellow light time is created. Further more,mathematical model of effective yellow light time is established. By fit-ting the model to practical situation,the rationality of the model is validated.
