Abstract: The automatic generation of multiple sets of directions for navigating geographically to a specific destination without specification of an origin. Based on the destination, candidate roads or other transportation conduits are selected for analysis. Candidate meta-departure points are analyzed and selected along the roads based on distribution about the destination, cardinal directions relative to the destination, road metadata, distance to the destination, driving time, and other factors. The number of departure points generated to represent routes to the destination from the several logical cardinal directions is minimized. The generated departure points also represent routes that a majority of people would likely take to the destination. Additionally, the generated departure points originate from places that users are likely to be familiar with and can get to without additional guidance. The final instruction sets for navigating to the destination are presented along with a map that identified the departure points.

Abstract: A geographic navigation system for segmenting a received set of instructions (or directions) that guide a user over a geographic route from a starting location to an ending location, and then abbreviating a subset of the instructions related to the inexact or familiar regions into a more concise and relevant form, yet retain all the information for guiding the user on the trip. Route segmentation occurs before instruction abbreviation by segmenting the route into multiple logical components in which abbreviation can be applied. After the need for instruction abbreviation is recognized and the route is segmented, techniques and designs are employed to generate understandable strings that describe the abbreviated directions as well as controls that allow optimization of the user experience.
