Abstract

The application discloses a saturation intersection group multi-layer boundary iterative learning control method and device based on MFD. Compared with the prior art, the iteration frequency of the method provided by the application can be obviously reduced, the convergence speed is effectively improved, so that the time-lagging problem is improved; and meanwhile; the double-layer boundary controlis performed on a jam area and a transition area by utilizing a feed-forward and feedback iterative learning controller, the boundary in-out vehicle flows at the jam area and the transition area areregulated, so that various traffic signal evaluation indexes of the jam area and the transition area are obviously improved, the entire traffic running efficiency of the control region is improved, and the boundary 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 ...
