Moving objects database has been active in the database community during the last 20 years. The task is to manage spatial objects continuously changing their locations over time. Users send their queries to know when and where of objects and will benefit from historical trips. Besides location and time, transportation modes such as BUS and WALK illustrate the geographical environment and describe in detail how objects move in available spaces. Such pieces of information represent preferences and habits for travelers, but do not receive adequate attention in the literature. Moving objects databases should enhance the capability to handle not only spatial objects continuously changing locations over time but also transportation modes in order to provide comprehensive knowledge about real-world objects. This book makes a complete and systematic introduction about moving objects with transportation modes, including data model, data generator, 3D visualizing moving objects, searching visible points in obstacle space, trip planning in diverse environments, indexing and querying moving objects with transportation modes, and a benchmark for moving objects with transportation modes.
