Abstract
With the rapid development of cities, traffic congestion is more likely to evolve into regional forms of congestion. To alleviate regional traffic congestion in cities while improving the traffic efficiency of road networks, a boundary control method is proposed. This method takes the optimal accumulation of the protected region as the control target and restricts the vehicles entering the protected region when the accumulation exceeds the optimal accumulation. For the optimal accumulation, a macroscopic fundamental diagram (MFD) is constructed. To achieve the control objective of optimal accumulation, the optimal inflow is estimated by a PID control algorithm based on a BP neural network. Then, the signal timing scheme of the boundary intersection is adjusted according to the optimal inflow. Finally, the proposed boundary control method is simulated according to the example road network. The simulation results show that the boundary control method can effectively improve the traffic congestion of the regional road network.
