Personalized Map Routes

A method and implementing computer system are provided which collects annotation information from users of a mapping site, associates the annotation with particular segments of a travel route, scores the annotations and constantly adjusts the scores of the annotations in determining preferred travel routes.

The user can request updates to the annotations if their scoring changes after the route is provided.
