Modeling Trajectory Data as a Directed Graph

In the last decade, usage of personnel smartphones has tremendously increased. Almost everyone is using cell phones, which are communicating with location-aware devices. The large amount trajectory data is produced from these devices and can be used for information services. The one of the key elements in mining of GPS or mobility data is the … Read more

Modeling and Querying Trajectories using Neo4j Spatial and TimeTree for Carpool Matching

Abstract—With the the exponential growth of location aware devices, analysis of human movements has been the subject of several studies. Problems related to urban mobility such as vehicle congestion are serious concern in cities. Carpooling is one of the solutions to soften congestion problem. This paper presents a novel matching method for carpooling. Trajectories are … Read more
