    摘要: A method, computer system, and computer readable product for trajectory data compression are disclosed. In embodiments, the method comprises generating spatial data for one or more moving objects; projecting the data onto a network comprised of a plurality of trajectories, the network constraining movement of the one or more moving objects; and storing the projected data in a data store. In embodiments of the invention, the method further comprises translating updates and queries to the spatial data, using specified data of the network, into links to the data store, and using the links to update and query the data store. In embodiments of the invention, the specified data of the network are stored in a network store. In embodiments of the invention, each of the trajectories includes one or more sub-trajectories, and the projecting the spatial data onto a network includes projecting the spatial data onto the sub-trajectories.

    摘要: Provided are systems, methods, and media for building a prioritized group trip object to generate a social trip plan recommendation. An example method includes receiving a static trip grouping scheme object for a group of users. Generating an interactive customized scheme object (ICSO) for each user based, at least in part, on the received static trip grouping scheme object and on a set of user preferences of the user such that a plurality of ICSOs are generated for the group of users. Merging the plurality of ICSOs to generate a prioritized group trip ICSO. Generating a recommended trip plan for the group based, at least in part, on the prioritized group trip ICSO.
