AD-HOC NAVIGATION INSTRUCTIONS

A computing device may implement a method for providing navigation information regarding a current trip by a user without the user having previously initiated a navigation session. The method may include receiving a request for navigation information regarding a current trip by a user prior to a user initiating a navigation session, and determining a destination for the current trip. The method may also include generating one or more sets of navigation directions for traveling from a current location of the user to the destination along one or more routes based on a current trajectory of the user, and providing a response to the request for navigation information based on the generated one or more sets of navigation directions.
