Method of operating a navigation system to provide a pedestrian route
First Claim
Patent Images
1. A computer implemented method of operating a navigation system to provide a pedestrian route, the method comprising:
- receiving an origin and a destination;
determining, using a processor, a plurality of candidate solution routes each comprising a plurality of sidewalks and crosswalks that form a continuous navigable route between the origin and the destination, wherein the sidewalks are associated with road segments and motor vehicles are prohibited from traveling the sidewalks;
receiving data indicative of a user selection option for safety consideration of crosswalks;
performing, using the processor, a comparison of the plurality of candidate solution route based on the user selection for safety consideration of crosswalks,wherein when the user selection for safety consideration of crosswalks is turned on, a first candidate solution route from the origin to the destination having a first distance is selected, and when the user selection for safety consideration of crosswalks is turned off a second candidate solution route from the origin to the destination having a second distance is selected, wherein the first distance is greater than the second distance, and generating route guidance including a safety advisory.

Abstract
A computer implemented method of operating a navigation system to provide a pedestrian route is provided. The method comprises receiving a request for a route from an origin to a destination. The method evaluates a plurality of pedestrian paths by accessing data representing the pedestrian paths to determine a safety cost associated with including the pedestrian path in the route. The safety cost indicates a safety risk for the pedestrian. The method provides the route comprising the pedestrian paths that form a continuous navigable route between the origin and the destination that minimize the safety cost.

10. A navigation system that provides a pedestrian route, the method comprising:
-
a geographic database including a pedestrian maneuver table; a computer; and a route calculation program executed on the computer, the route calculation program configured to; receive an origin and a destination, identify a first solution route and a second solution route based on the origin and the destination, wherein the first solution route is longer than the second solution route, identify a user selection for safety consideration of crosswalks, compare the first solution route and the second solution route based on the user selection for safety consideration of crosswalks and at least one characteristic of a crosswalk in the second solution route, and select the first solution route based on the user selection for safety consideration of crosswalks even though the first solution route is longer than the second solution route. - View Dependent Claims (11, 12, 13)

14. A computer implemented method of operating a navigation system to provide a pedestrian route, the method comprising:
-
receiving a request for a route from an origin to a destination; receiving a user preference for safety consideration in pedestrian routing; identifying, using a processor, a plurality of pedestrian paths by accessing data representing the pedestrian paths to determine which of the plurality of pedestrian paths include crosswalks and types of intersections associated with the crosswalks; performing, using the processor, a comparison of the plurality of pedestrian paths based on the user preference, wherein; the processor selects a first route from the origin to the destination including fewer crosswalks or less complex intersections when the user preference for safety consideration is activated; and the processor selects a second route from the origin to the destination including more crosswalks or more complex intersections when the user preference for safety consideration is deactivated. - View Dependent Claims (15, 16, 17, 18, 19, 20)
