A method for determining navigation prompt information includes: acquiring a first set of road shape points on a target road segment from map data; determining a target turning angle formed by the first set of road shape points according to line segments between every two adjacent road shape points in the first set of road shape points; searching the target road segment for a bifurcation-free turning position according to the target turning angle, the bifurcation-free turning position being used for representing a turn road segment with a bifurcation-free junction on the target road segment; and setting the navigation prompt information according to the bifurcation-free turning position when the bifurcation-free turning position is found and it is determined that the navigation prompt information needs to be set to the turn road segment according to road information of a road segment adjacent to the target road segment.
