| 摘 要： | 在基于固定网络的移动对象轨迹查询方面.现有的索引模型只能管理移动对象当前和过去或将来轨迹的查询,它们都不能同时实现移动对象的现在,过去和将来轨迹查询.本文在IMORS的索引结构基础上进行改进并提出了一种新的索引结构.它能实现基于固定网络的移动对象的全时态索引.

| Abstract: | In indexing moving objects trajectories on fixed networks,existing index model only can manager the past, present or future,trajectory querying of moving object.They are not able to index the present,past and future positions at the same time.In this paper,a novel index model based on IMORS is proposed to support querying the past, present and future positions on fixed networks. |
