Panda: A Predictive Spatio-Temporal Query Processor

This paper presents the Panda system for efficient support of a wide variety of predictive spatio-temporal queries that are widely used in several applications including traffic management, location-based advertising, and ride sharing. Unlike previous attempts in supporting predictive queries, Panda targets long-term query prediction as it relies on adapting a well-designed long-term prediction function to: scale up to large number of moving objects, and support large number of predictive queries. As a means of scalability, Panda smartly pre-computes parts of the most frequent incoming predictive queries, which significantly reduces the query response time.
