摘要：
In view of the unbalanced distribution of traffic flows in urban traffic networks, this paper proposes a perimeter control strategy of road networks based on consistency thought. Firstly, the evolution of traffic flows in regional boundary links is modeled by vehicle conservation equation, and the perimeter feedback control approach is proposed with the occupancy consistency of the links in network as control objective, and the signal timing of boundary intersections as control input. And then the analytical relationship between the traffic flow input of boundary links and the discharging proportion of internal links is deduced. Finally, chose the measured data of the road network to verify the applicability of the perimeter control strategy, which shows that the perimeter control strategy can not only effectively improve the unbalanced distribution of traffic flow in the road network, but also reduce the average delay, queue length and other indicators and improve the operation efficiency of the network. © 2020, Editorial Department of Control Theory & Applications South China University of Technology.
