A Hybrid Aggregate Index Method for Trajectory Data

A Hybrid Aggregate Index Method for Trajectory Data

The aggregate query of moving objects on road network keeps being popular in the ITS research community. The existing methods often assume that the sampling frequency of the positioning devices like GPS or roadside radar is dense enough, making the result’s uncertainty negligible. However, such assu...
