Abstract: A new index structure, DSD+, which is the dynamic sketch with direction index, is proposed to solve the problem of aggregate query of moving objects in the road network environment. This technique combines the sketch technology, which can solve distinct counting problem, and the AMH+ technology, which can give out efficient approximate aggregate query results with smaller storage space; and utilizes the characteristics of aCN-RB-tree that supports aggregate by the direction property. The performance analysis and the experimental results show that, with the same query time and precision, the query storage space of the proposed DSD+ index structure is less than that of existing index structures.

Key words: computer application, road networks, aggregate query, index of moving objects
