摘要
本文研究了交叉口信号控制的二层规划模型的求解算法.上层模型采用了一种直接处理约束的改进的粒子群算法,下层则采用仿射尺度内点算法,得到了一种信号控制二层规划模型.并对模拟路网进行了数值实验,表明算法是有效的和可行的.
In this paper, a more practical bi-level programming model is proposed by considering the intersection delay explicitly. A revised Particle Swarm Optimization （PSO） algorithm is used to solve the upper problem and the Gradient Projection Algorithm with affine scaling is employed as the lower level problem solver. Numerical experiments show that the algorithm presented is both effective and efficient.
