摘要

本文提出了高速公路匝道计量问题的离散时间最优控制公式，并给出了求解该问题的高效计算方法。该问题具有特殊的结构:其控制约束可以通过变量变换简化为框约束。采用改进的拟牛顿法求解该变换问题，在交通动力学较为复杂的情况下，该方法优于共轭梯度法。

An optimization algorithm for freeway traffic control

This paper presents a discrete time optimal control formulation for the freeway ramp metering problem and a computationally efficient procedure to solve it. The problem has a special structure: its control constraints can be reduced to box constraints through a variable transformation. This transformed problem is solved using a modified quasi-Newton method, which is shown to be superior to the conjugate gradient method in cases where traffic dynamics is more complicated.
