Automatically generating route directions based on signpost data
First Claim
1. A method for automatically generating route directions based on signpost data, the method comprising:
- calculating a calculated route from an origin to a destination, wherein the calculated route includes multiple decision points where a user has more than one option to take;
receiving geo-stamped images of signposts located at each decision point from the multiple decision points;
compiling at least one series of signposts, wherein each series has a common signpost content;
resolving conflicts in any overlapping series by using a measure of relative density of signpost content;
replacing one or more decision points of the calculated route with instructions referring to the common signpost content of the at least one series of signposts; and
displaying geo-stamped images of signposts of the at least one series of signposts having the common signpost content on a display in a motor vehicle.

Abstract
A method, system, and/or computer program product automatically generates route directions based on signpost data. A calculated route from an origin to a destination includes multiple decision points where a user has more than one option to take. Geo-stamped images of signposts located at each decision point from the multiple decision points are received, and one or more series of signposts is compiled, where each series has a common signpost content. Conflicts in any overlapping series are resolved by using a measure of relative density of signpost content, and one or more decision points of the calculated route are replaced with instructions referring to the common signpost content of the series of signposts. Geo-stamped images of signposts of the series of signposts having the common signpost content are then displayed in a motor vehicle.

11. A computer program product for automatically generating route directions based on signpost data, the computer program product comprising a computer readable storage medium having program code embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, and wherein the program code is readable and executable by a processor to perform a method comprising:
-
calculating a calculated route from an origin to a destination, wherein the calculated route includes multiple decision points where a user has more than one option to take; receiving geo-stamped images of signposts located at each decision point from the multiple decision points; compiling at least one series of signposts, wherein each series has a common signpost content; resolving conflicts in any overlapping series by using a measure of relative density of signpost content; replacing one or more decision points of the calculated route with instructions referring to the common signpost content of the at least one series of signposts; and displaying geo-stamped images of signposts of the at least one series of signposts having the common signpost content on a display in a motor vehicle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A computer system comprising:
-
a processor, a computer readable memory, and a computer readable storage medium; first program instructions to calculate a calculated route from an origin to a destination, wherein the calculated route includes multiple decision points where a user has more than one option to take; second program instructions to receive geo-stamped images of signposts located at each decision point from the multiple decision points; third program instructions to compile at least one series of signposts, wherein each series has a common signpost content; fourth program instructions to resolve conflicts in any overlapping series by using a measure of relative density of signpost content; fifth program instructions to replace one or more decision points of the calculated route with instructions referring to the common signpost content of the at least one series of signposts; and sixth program instructions to display geo-stamped images of signposts of the at least one series of signposts having the common signpost content on a display in a motor vehicle; and
whereinthe first, second, third, fourth, fifth, and sixth program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory. - View Dependent Claims (20)
