Summary:The invention provides a regional dynamic boundary control method and system for preventing the queuing overflow of a boundary road section, and the method comprises the steps: estimating the number of queuing vehicles of the boundary road section through employing a Kalman filtering extension method according to the obtained traffic flow information of the boundary road section, and calculating the maximum total number of receivable vehicles of the boundary road section; dynamically dividing the boundary road sections by utilizing the estimated value of the number of queuing vehicles of eachboundary road section and the maximum total number of receivable vehicles to obtain a boundary road section set with sufficient available storage space and a boundary road section set with insufficient available storage space; obtaining a key cumulant of the region according to a preset region macroscopic basic graph model, and estimating a predicted cumulant of the region in the next sampling period; and according to the
