USER TRIP LIBRARIES

One or more techniques and/or systems are provided for generating a trip library. Locational information, obtained from a device of a user (e.g., a mobile device, a wearable device, etc.), may be evaluated to identify trips traveled by the user and terminals traveled to by the user above a visitation frequency threshold (e.g., work, a favorite coffee shop, school, etc.). The trips and terminals may be evaluated to determined preferred trips that the user travels above a travel frequency threshold (e.g., routes that the user prefers to travel when going to a terminal, such as routine routes to a grocery store, work, etc.). A trip library, comprising the terminals, the preferred trips, and conditional likelihoods that he user will travel to a terminal given one or more conditions, may be created and used to preemptively provide the user with suggestions (e.g., notice of an event, coupon, alternative route, accident, etc.).
