METHOD OF OPERATING A NAVIGATION SYSTEM TO PROVIDE A PEDESTRIAN ROUTE
First Claim
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 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;
evaluating the candidate solution routes by accessing data representing the sidewalks and crosswalks from a geographic database to determine a safety cost associated with including the sidewalks and the crosswalks in the candidate solution route, wherein the safety cost indicates a safety risk for the pedestrian; and
generating route guidance for the candidate solution route that minimizes the safety cost, wherein the route guidance includes 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.

11. A navigation system that provides a pedestrian route, the method comprising:
-
a geographic database; a computer; and a route calculation program executed on the computer, the route calculation program receives an origin and a destination, computes a solution route between the origin and the destination comprising a series of pedestrian paths that form a continuous navigable route between the origin and the destination for travel by a pedestrian, wherein the candidate pedestrian paths for the solution route are evaluated for a pedestrian safety cost and included in the solution route to minimize safety risk. - View Dependent Claims (12, 13, 14)
