RHTP-STD:Real-time Heuristic Trajectory Prediction Based on Spatio-Temporal Databases
摘要
Abstract
With pervasiveness of mobile devices and internet of things technologies,collection and analysis of spatio-temporal data become increasingly important.Trajectory prediction,especially real-time trajectory prediction,is crucial for various application fields,such as intelligent transportation and urban planning.However,existing trajectory prediction methods often fail to guarantee prediction accuracy as well as meet real-time requirement.Moreover,real-time data is usually incomplete or noisy,necessitating that prediction algorithms adapt to incomplete trajectory information.To address these challenges,Real-time Heuristic Trajectory Prediction Based on Spatio-Temporal Databases(RHTP-STD)is proposed.RHTP-STD utilizes MobilityDB database platform to store and manage trajectory data and employs a graph construction algorithm to transform trajectory data into spatio-temporal graphs.Subsequently,RHTP-STD em-ploys a heuristic algorithm that integrates historical and real-time data to rapidly predict future trajectories of moving objects.Experi-mental results on Argoverse dataset demonstrate that RHTP-STD outperforms existing methods in terms of prediction accuracy and real-time performance.Furthermore,applicability of RHTP-STD in different application scenarios is discussed,and potential future re-search directions are presented.关键词
