Abstract

This application discloses a MFD-based multi-layer boundary iterative learning control method and device for saturated intersection groups. Compared with the prior art, the method provided by this application can significantly reduce the number of iterations, effectively improve the convergence speed, and make the time At the same time, the feed-forward feedback iterative learning controller is used to control the double-layer boundary of the congestion area and the transition area, and the traffic flow in and out of the congestion area and the transition area is adjusted, so that the traffic in the congestion area and the transition area The signal evaluation indicators have been significantly improved, improving the overall traffic operation efficiency in the control area, and the border control effect is more ideal.

Description

technical field [0001] The present application relates to the technical field of traffic control, in particular to an MFD-based multi-layer boundary iterative learning control method and device for saturated intersection groups. Background technique [0002] With the rapid development of social economy, the number of cars has increased sharply, and the problem of urban traffic congestion has become more and more serious, which has brought huge challenges to urban traffic. Traffic control problem in oversaturated intersection clusters. [0003] At present, traffic management and control methods based on Macroscopic Fundamental Diagrems (MFD) are applied to the road network to effectively control saturated intersection groups, including model-based feedback control methods and MFD-based iterative learning control method. But there are two problems in the current model-based feedback control method and MFD-based iterative learning control method: [0004] (1) The problem of ...
