Volumes of GPS recorded trajectory data in ubiquitous urban sensing applications are increasing fast. Many trajectory queries are both I/O and computing intensive. In this study, we propose to develop the U 2 STRA prototype system to efficiently manage large-scale GPS trajectory data using General Purpose computing on Graphics Processing Units (GPGPU) technologies. Towards this end, we have developed a trajectory data layout schema using simple in-memory array structures which is not onlydoi:10.1145/2390226.2390229 fatcat:7v2spz6lazdgpbcbynxpvxu6xe
