Routes that are optimal in general for a particular travel need may at times be unsuitable in a specific instance because of various factors such as construction, weather, accidents, rush hour traffic, road surface conditions, presence of crowds, etc. The impact of such factors on a person’s travel plans can depend on the specifics of the person’s travel circumstances, such as travel mode, vehicle characteristics, etc. This disclosure describes techniques to proactively deliver travel routing guidance personalized to a user, based on user-permitted contextual factors. If the user permits, the personalized routing guidance is adjusted to avoid one or more of a number of dynamic factors that can adversely impact specific routes at the time of the user’s travel. With user permission, route guidance can be generated passively, without an actual request from the user, and notifications or alerts can be proactively provided to the user.
