Embodiments of the present application provide a method, device, device, and computer-readable storage medium for determining a road speed limit, including: obtaining speed limit information; For the road, the speed limit information includes the speed limit value of the first road; determine the first road link matching the first road, and the speed limit value of the road included in the first road link is the same as the speed limit value of the first road. This method determines the first road actually corresponding to the speed limit information through the position information of the current road in the electronic map, which can avoid setting the speed limit value of the first road as the speed limit value of the current road by mistake, thereby improving the speed of determining the speed limit of the road. At the same time, by determining the first road link that matches the first road, other roads with the same speed limit value as the first road are automatically calculated, which improves the efficiency of determining the road speed limit.
