Method of Collecting Information for a Geographic Database for Use with a Navigation System
First Claim
1. A computer implemented method of operating a navigation system comprising:
- obtaining a request to calculate a pedestrian route from an origin to a destination for travel by a pedestrian;
obtaining a walking preference for the pedestrian route identifying a feature of the pedestrian route;
accessing data representing at least one pedestrian path from a geographic database associated with the navigation system, wherein the data representing the pedestrian path includes lighting level attribute information for the pedestrian path;
determining a valid solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths that support the walking preference.

Abstract
A method for operating a navigation system computes a pedestrian route for travel by a pedestrian. A request to calculate the pedestrian route from an origin to a destination and a walking preference for the pedestrian route identifying a feature of the pedestrian route are obtained. A geographic database associated with the navigation system is accessed for data representing at least one pedestrian path. The data representing the pedestrian path includes lighting level attribute information for the pedestrian path. A valid solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths that support the walking preference is determined.

14. A navigation system comprising:
-
a processor, a geographic database associated with the processor, a route calculation program executed on the processor, wherein the route calculation program obtains a request for a pedestrian route to a destination and a route preference for the pedestrian route, obtains data from the geographic database to determine the pedestrian route to the destination comprising a series of connected pedestrian segments that satisfies the route preference, wherein the data obtained from the geographic database includes information indicating wheel-chair accessibility of the pedestrian segments. - View Dependent Claims (15, 16, 17, 18)
