1. A method for determining navigation prompt information performed by a computer device, comprising:
acquiring a first set of road shape points associated with a target road segment from map data;
determining at least one target steering angle between every two adjacent line segments formed by every three adjacent road shape points in the first set of road shape points;
searching the target road segment for a non-fork diversion position according to the target steering angle, the non-fork diversion position being used for indicating that the target road segment includes a turn road segment with a non-fork junction on the target road segment; and
setting the navigation prompt information according to the non-fork diversion position when it is determined that the navigation prompt information is to be broadcast for the turn road segment according to road information of a road segment adjacent to the target road segment in a preset driving direction along the target road segment.
