The invention provides a traffic control area division method and device, and the method comprises the steps: obtaining a road network topological relation and road network data in a traffic control area; according to the road network topological relation, constructing a similarity matrix representing the connection relation between the intersections in the road network; according to the similarity matrix and the road network data, constructing a similarity adjacent matrix representing a circulation relationship between intersections in the road network; determining a degree matrix of the road network according to the similarity adjacent matrix; determining a Laplacian matrix of the road network according to the similarity adjacent matrix and the degree matrix; determining a characteristic value and a characteristic value difference value of the Laplacian matrix of the road network, and finally dividing the traffic control area according to the characteristic value difference value. The division rationality of the traffic control region is improved, and the effect of performing partition control on the traffic control region is improved.
