The invention discloses a road network balance control method and system based on big data. The method comprises the following steps: acquiring and analyzing a road network spatial topological structure, and acquiring a detection equipment layout, an equipment type, detectable parameters and the like on a road network; calculating state indexes of road network nodes such as intersections and road sections in the road network; according to the correlation degree of each node in the road network, a clustering method is adopted to carry out space segmentation on the road network to form relatively independent road sub-networks; classifying the running states of the road subnets according to the state indexes, and calculating the bearing capacity of each road subnet in a crowded state; and key nodes inside and outside the controlled subnet are identified, and a balance control strategy is implemented. According to the invention, vehicle distribution in the road network space is balanced, and the passing efficiency of road network vehicles is improved.
