COLLOQUIAL OR USER-FAVORED ROUTE BASED NAVIGATION INSTRUCTIONS

A route between start and destination locations is generated, and a navigation device presents navigation instructions to a user describing the route. The navigation instructions can be colloquial navigation instructions, which are instructions that are more humanized (e.g., more conversational in language and format, or consistent with the manner in which people typically talk to one another in familiar or informal conversation). The route that is generated can be based on one or more user-favored routes. A user-favored route is a route between two locations that is determined to be desired, preferred, or otherwise favored by a user over other routes. The route that is generated can be generated to include at least part of one or more user-favored routes.
