| 摘 要： | Ｇｒｙｃｋｏ等人证明了在由交通灯控制的瓶颈路段上，排队汽车的队长渐近期望相对于队长过程的起始分布是不变的；这就可以考虑用取该渐近期望最小来确定绿灯的最优持续时间，Ｇｒｙｃｋｏ等给出了相应的解析证明，这里用数值分析的方法给出进一步的研究结果。

| Abstract: | Grycko,et al proved that the asymptotic expectation of the queue lengths of waiting vehicles at a bottleneck controlled by traffic lights is invariant against alterations of the starting distributions of the process of the queue lengths which suggests determining an optimal duration of the green phase by minimizing the said asymptotic expectation. In addition to allalytical proofs given by Grycko, et al, the different facts are investigated now by a numerical analysis. |
