In this field, Christian et proposed a Island method in 2005, it is a k nearest neighbor query method of moving objects based on road network,but this method has three flaws which are k nearest neighbor query in constrained road network,traffic-jam exploration and optimize of Island's radius. This article has studied k nearest neighbor query of moving objects based on road network in view of above three aspects ,and proposed the Island+ method, which has made the improvement to the memory structure and trajectory preservation of neighbor objects.

在这一领域，Christian等人在2005年提出了Island方法，它是一种基于路网的移动对象k近邻查询方法，但是这种方法存在以下不足的地方，第一，该方法对路网没有任何限制条件；第二，没有给出明确的数据存储结构；第三，区域半径一致，效率不高。
