摘要:In this work, we proposed a discrete boundary-feedback-control strategy for urban traffic flow based on Macroscopic Fundamental Diagram. Firstly, the road network is divided into several sub-regions according to the degree of correlation of road intersections, and then the Macroscopic Fundamental Diagram characteristics of each traffic sub-region are analyzed to obtain the optimal critical value of vehicles in each sub-region. For a single traffic sub-region, when the number of accumulated vehicles in the sub-region exceeds the optimal threshold, we control the entry and exit of the vehicle at the boundary of the traffic sub-region by adjusting the traffic timing of the traffic lights at the boundary of the sub-region. The Vissim simulation experiment was conducted to verify that the vehicle delay in the road network was significantly reduced with the discrete boundary-feedback-control strategy, as well, the road congestion was alleviated, the travel efficiency was improved, and the road network traffic operation status was improved.
