<p>A computer system and media for delivering routing information are provided. The computer system includes a routing engine, a database, and routing network that are employed to respond to routing requests and user modifications of routing information received in response to the routing requests. The routing engine receives the routing requests and generates routing information that illustrates a route and metadata for directions that guides a user when navigating the route. A user that is dissatisfied with the routing information may use route modification tools to alter the route in a manner that is consistent with the user's understanding of alternate routes that may supplement the routing information provided by the routing engine. The computer system receives the user modifications, stores the user modifications, and updates the routing network to learn the alternate route provided in the user modifications.</p> |
