Abstract
In order to determine navigation instructions, a mapping server can use digital map data, which can include a set of intersections connected by road segments. In some cases, the mapping server generates navigation guidance data for one or more intersections of digital map data. Responsive to a request for navigation instructions from a client device, the mapping server can generate a navigation route between an origin and destination location, and a corresponding set of navigation instructions can be generated based on the navigation route. In some implementations, the generated navigation instructions are then modified to clarify or otherwise improve the quality of the navigation instructions. Finally, the finalized navigation instructions can be sent to a client device for display to the requesting user.
