基于微扰分析的红绿灯交叉口拥堵管理
Congestion management in traffic-light intersections via Infinitesimal Perturbation Analysis
摘要：
提出了一种交通灯交叉口的流量控制技术，旨在将队列长度调节到给定的参考设定值。该技术是基于多变量积分器的自适应增益，计算在每个控制周期通过评估IPA梯度的植物功能。此外，IPA梯度是可计算的在线，尽管没有详细的交通流模型。该技术被应用到一个两个交叉系统，它表现出鲁棒性的建模不确定性和计算误差，从而使我们能够简化在线计算，也许在牺牲精度，同时实现所需的跟踪。我们比较，通过仿真，一个集中的，联合两个路口控制与分布式控制的每个路口分别的性能，并显示出类似的性能的两个控制方案的参数范围。
英文摘要：
We present a flow-control technique in traffic-light intersections, aiming at regulating queue lengths to given reference setpoints. The technique is based on multivariable integrators with adaptive gains, computed at each control cycle by assessing the IPA gradients of the plant functions. Moreover, the IPA gradients are computable on-line despite the absence of detailed models of the traffic flows. The technique is applied to a two-intersection system where it exhibits robustness with respect to modeling uncertainties and computing errors, thereby permitting us to simplify the on-line computations perhaps at the expense of accuracy while achieving the desired tracking. We compare, by simulation, the performance of a centralized, joint two-intersection control with distributed control of each intersection separately, and show similar performance of the two control schemes for a range of parameters.
