Fork type screening calculation method, device and equipment and readable storage medium

The invention provides a fork type screening calculation method, device and equipment and a readable storage medium, and relates to the technical field of navigation map making, and the method comprises the following steps: obtaining a navigation path; performing road intersection screening on the navigation path to obtain all road intersections in the navigation path; according to a relationship between all the road intersections and preset basic road network data, obtaining associated branches corresponding to the road intersections; vectorization is carried out according to the associated fork corresponding to each road intersection, and a fork vector corresponding to each associated fork is obtained; and performing angle judgment according to the fork road vector corresponding to each road intersection to obtain a fork road type corresponding to each associated fork road. According to the method, when the environment above and below the path is considered, the potential influence of the adjacent crossed r
