Road network data generation method and device, computing device and storage medium

The invention relates to a road network data generation method and device, a computing device, a computer readable storage medium and a computer program product. The road network data generation method comprises the steps of obtaining the initial map data, wherein the initial map data comprises the road chain information about a plurality of road chains and the node information about a plurality of nodes, and each node in the nodes is an intersection point of at least two road chains; determining the intersection information about a plurality of intersections based on the node information; based on the intersection information and the road chain information, determining the road section information about multiple road sections and the road information about at least one road, wherein each road section represents a set of one or more road chains between two adjacent intersections, and each road represents a set of multiple road sections which are sequentially connected end to end; and generating the road netwo
