In this paper, first, by using the quantitative analysis method for correlation degree between neighboring intersections, some calculation formulas are put forward to calculate the correlation degree of neighboring intersections and the combinatorial correlation degree of multi-intersections. Next, by defining the solution space, the constraint conditions and the evaluation criteria of the division scheme, a division model of coordinated control subareas is established. Then, by using the layer diffusion algorithm, the subarea division scheme is analyzed and evalua- ted, and the whole division process is given. Finally, an example is presented to discuss the division method of coordinated control subareas based on correlation degree analysis.
