Dynamic compound indexing method for moving objects based on road distribution
基于道路分布的移动对象动态组合索引方法

Traffic management information service requires an efficient indexing method to manage moving objects. Aiming at such requirement,a dynamic compound indexing structure for moving objects based on road distribution was proposed. It adopted bottom-up updating algorithm and road segments connecting method to improve updating and accessing efficiency. Experimental results prove that such compound index has better performance in updating and inquiring.
