Abstract: Systems and methods are disclosed herein for providing a model of a vehicle to a rider. In an embodiment, the systems and methods determine that a driver has accepted a task to operate a vehicle from a first location to a rider location. The systems and methods then access a model corresponding to the vehicle, determine a direction of movement of the vehicle, and determine a relative orientation of the vehicle with respect to the rider based on the first location, the direction of movement of the vehicle, and the rider location. The systems and methods generate for display, on a client device of the rider, the model at an angle determined based on the relative orientation.

Abstract: Systems and methods are provided for partitioning a geographical area to generate a plurality of partitions for the geographical area, determining a plurality of points of interest located in the geographic area, determining a popularity of each of the plurality of points of interest based on a trip count comprising at least one of a number of ridesharing pickups or a number of ride-sharing drop-offs at the point of interest, and for each partition of the plurality of partitions of the geographical area, determining one popular point of interest located within the partition and associating the one popular point of interest with the partition.

Abstract: Systems and methods are provided for generating a plurality of cells representing a geographical area, where each cell of the plurality of cells comprises a plurality of address points representing addresses in the cell, and normalizing each address corresponding to each address point into a hierarchical structure of address components. The systems and methods further provide for traversing a hierarchical structure of address components for address points in a first cell to determine address components that are different between address points in the first cell, and for each address component that is different between address points in the first cell, generating an anonymized address component using a common prefix for the address component or a combination of address components. An anonymized address is generated for the first cell comprising at least one anonymized address component, and the anonymized address is stored for the first cell.

Abstract: A computing system uses tree data structures summarizing map builds to identify differences between map builds. The tree data structures include nodes summarizing portions of geographic regions of map builds. Responsive to a request to compare a first and second map build, the computing system accesses the tree data structures for the first and second map builds and identifies differences by traversing the tree data structures in lockstep and comparing the hash values for corresponding nodes in the tree data structures. The computing system traverses the tree data structures by identifying nodes that are different between the tree data structures until one or more bottom-level nodes are identified as different. The computing system identifies map features corresponding to the identified bottom-level nodes as different and transmits the identified map features to a client device associated with the request.

Abstract: Systems and techniques are described for blind evaluation of nearest neighbor queries. Locations of multiple users in an original space are received. The locations in the original space are encoded into encoded locations in a transformed space. A relative proximity of the encoded locations in the transformed space is maintained after the encoding. Multiple keys corresponding to the multiple users are generated. Each key enables a reverse transformation of an encoded user location in the transformed space to an original user location in the original space. The multiple keys are provided to the corresponding multiple users, and the encoded locations in the transformed space are provided to a device. An order of computations required to reverse transform the encoded locations in the transformed space to the locations in the original space in the absence of a key is greater than a computational threshold.
