Abstract
A system and method are disclosed that provide an end user of a navigation program with information about walking to a desired destination in combination with information about driving to or close to the desired destination. In addition to the calculation of a route for driving to the desired destination, the navigation program uses data in a geographic database to calculate one or more routes to reach the desired destination by walking from locations within a walking threshold around the desired destination. In calculating these one or more walking routes, the navigation program uses the data in the geographic database to assess the suitability of roads around the desired destination for pedestrian travel. In calculating these one or more walking routes, the navigation program can also include road segments in the walking routes without regard for travel restrictions that only apply to vehicular traffic. Additionally, if the navigation program is installed in a vehicle, the navigation program may indicate the walking distance to the desired destination along one of the calculated walking routes as the vehicle approaches the desired destination. Additionally, the navigation program…
