| 摘 要： | 城市交通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,黄灯时间的长短设置直接影响城市交通的状况.建立保守黄灯时间数学模型,通过逐步修订,建立了更符合实际情况的有效黄灯时间的数学模型,并在城市道路十字路口黄灯时间确定为4s的情况下,对安全停车距离进行了分析,指出困境区域的存在性与进行深入研究的必要性.

| Abstract: | Crossing roads are the nodes of conflicted traffic flow in urban traffic.The safety problem is getting serious.Mathematical models of yellow light time and effective yellow light time are developed.In the case of yellow light time confirmed in crossing road of urban traffic,safety stopping distance and dilemma zone problems are draw forth in road traffic.Dilemma zone is really existence in some place,it is very necessary to further study. |

| Keywords: | traffic engineering yellow light time model kinematics equation effective yellow light time dilemma zone safely stopping distance |
