摘要
讨论了多相位控制条件下交叉口的周期和绿信比优化模型,并将其转化为一个带约束的多变量函数求极值问题;而后在满足交通控制所需精度的条件下提出求解该模型的改进“爬山”算法;最后,将模型与算法嵌入到交通设计与配时优化计算机辅助系统TJSIG中,结合厦门试验工程对模型算法进行了验证。
This paper made an analysis of the optimal control models of the cycle and splits for a multi - phase signalized intersection, and transformed it to a multi-variable function optimizing problem with boundary conditions. Then an improved hill-climbing algorithm was put forward which can meet the precision of the traffic control. In the end,a case study in Xiamen was done to validate the control model and algorithm through TJSIG.
