Abstract
This application provides a method and an apparatus for generating road network data of an intersection area, and the intersection area connects a plurality of roads. The method includes: obtaining data of a road link of each of the plurality of roads, where the road link includes an entry link and an exit link; calculating coordinates of an intersection point of an extension line of the entry link of each road and an extension line of an exit link of a neighboring road based on the data of the road link of each of the plurality of roads, where the coordinates of the intersection point are coordinates of an intersection node; and the neighboring road is a road counterclockwise adjacent to the road; or the neighboring road is a road clockwise adjacent to the road, where two intersection nodes in sequence are endpoints of an intra-intersection link.
