An embodiment of the invention discloses a technical scheme of determining a border line between road network partitions, in particular to a method and equipment for determining a road network partitioning border line. The method comprises the steps of: determining a border point based on road network data and partitioning information of road segments in the road network; determining a buffer zone between adjacent partitions based on the border point, the partitioning information of the road segments, and the road network data; and determining a border line between the adjacent partitions based on the buffer zone. Through adoption of the method and the equipment provided by the invention, the border lines for road network partitions can be accurately determined.
