In this demonstration, we introduce a system that is able to manage moving objects in all real world environments, e.g., road network, bus network and indoor. The complete trip of a person is managed by the system such as Walk, Car, Walk, and Indoor, where the precise locations of both outdoor and indoor movements are represented. Trajectories located in several environments are integrated into the same framework. The system supports the shortest path searching for start and end locations being in different environments, for example, from a room to a bus stop. A comprehensive and scalable set of moving objects is generated to simulate human movement in practice. Optimization methods are developed to efficiently answer novel queries regarding transportation modes and mobile environments. Most of these queries are not supported by existing methods because of the limitation of data representation.
