Abstract: A road data processing method, a device, and a storage medium are provided, and relate to the technical fields of intelligent transportation, cloud computing and spatiotemporal big data. The road data processing method includes: acquiring vehicle travelling trajectories of a road and a corresponding road unit in a road network; establishing a road vertical line for the road unit, and determining points of intersection of the vehicle travelling trajectories and the road vertical line; determining a width area of the road on the road vertical line according to position data of the points of intersection; and determining a midpoint of the width area as a road center point corresponding to the road vertical line.
