研究了基于一般信号相位结构的区域信号配时二层规划模型的求解算法.对于上层问题,将灵敏度分析方法和信赖域算法相结合,得到一种高效算法.而对于下层问题,则采用具有较高收敛速度的仿射尺度内点算法.还对上层问题采用一阶近似信赖域方法、二阶近似信赖域方法两种情形进行了数值对比试验.数值结果显示:一阶近似信赖域方法性能更好,可以应用于实际区域信号配时问题.
The algorithm of solving the two-layer programming model of regional signal timing based on the general signal phase structure is studied. For the upper-layer problem, the sensitivity analysis method and the trust-domain algorithm are combined to obtain an efficient algorithm, while for the lower-layer problem, High convergence rate of the affine scaling algorithm.An upper-level problem using the first-order approximation trust region method, second-order approximation trust region method two cases of numerical comparison test.Numerical results show that: First-order approximation trust region method performance more Well, it can be applied to real-time signal timing issues.
