By introducing the concept of group clustering degree in the group dynamics theory, some formulas are deduced to calculate the clustering degree at adjacent intersections. Then, by controlling the subarea border and setting the constraint conditions for subarea division, a layered substep strategy of subarea division for traffic control is developed and a subarea division model based on the group dynamics theory is established. Moreover, the complete acquiring process of optimal subarea division is presented, and the subarea division schemes are comprehensively analyzed and evaluated with the intersection group clustering algorithm. Example results indicate that the proposed division method of coordinated control subareas based on the group dynamics theory is effective because it decreases the total number of vehicle stops as well as the stop delay in road networks.
