Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for obtaining i) historical location data specifying geographic locations of the user over a period of time that is included in a user profile of the user and ii) predefined geographic location data specifying a predefined geographic location of the user that is included in the user profile of the user; identifying a pair of cross-contaminated geographic regions that both include geographic locations specified by the historical location data of the user profiles for each of a threshold number of users of the plurality of users, and in response, merging the pair of cross-contaminated geographic regions to define a merged geographic region; and merging the merged geographic region with additional geographic regions until a cross-contamination between a resulting merged geographic region created by the merging and other geographic regions is reduced to a specified level of cross-contamination.

Abstract: The present disclosure provides systems and methods for generating routing assignments. One example method includes obtaining delivery data associated with a plurality of objects to be delivered from an object distribution hub to a plurality of delivery destinations, wherein a plurality of loading areas are associated with the object distribution hub; obtaining data indicative of a current location for each of the plurality of objects within the object distribution hub; determining data indicative of a respective amount of time required to transfer each of the plurality of objects from its current location to each of the plurality of loading areas; determining routing assignment data based at least in part on the delivery destinations and the respective amount of time required to transfer each of the plurality of objects to each loading area; and providing the routing assignment data to facilitate loading and delivery of the set of one or more objects.
