The invention relates to the technical field of intelligent traffic control, in particular to an urban road network lane-level space-time resource allocation method in an intelligent network connection environment, and the method comprises the steps: constructing an urban road network model based on a plurality of signal intersections and a plurality of road sections; the pollution bearing capacity and the resource bearing capacity of the multiple edges are determined respectively, and the unilateral bearing capacity and the urban road network bearing capacity are determined based on the pollution bearing capacity and the resource bearing capacity; s3, lane-level space resource pre-allocation is carried out on urban road network space resources on the basis of preset passable traffic flow in unit time, the unilateral bearing capacity and the road network bearing capacity; s4, constructing a mixed traffic flow data set, and predicting a short-time lane-level passable state of the urban road network based on the mixed traffic flow data set; and S5, realizing optimal allocation of the lane-level space-time resources based on a lane-level space resource pre-allocation result and the short-time lane-level passable state. According to the invention, urban road network lane-level space-time resource allocation is realized.
