摘要在地图匹配过程中,待匹配路段初筛过程是影响其时间效率的关键。鉴于现有的路段初筛方法在最大检索范围的控制上仍有进一步缩减的空间,提出了一种四级交错式网格筛选方法。通过对深圳市GPS定位数据的检索实验表明: 该方法可有效缩减候选路段的筛选范围,并在保证筛选范围的稳定性上优于现有的方法; 通过有效控制候选路段的检索范围,进一步减少了检索时间。该方法在车载导航和大规模GPS数据处理等领域具有很大的应用价值。

Abstract：The primary filtering of the pre-matching road sections in the map matching algorithm, in which GPS point finds the closest approximation road for driving, is the key factor of the time efficiency. There is a great deficiency of redundant searching range in the existing primary filtering methods. To reduce the searching range, this paper proposes a novel four-level interlaced grid filtering method, which can efficiently narrow the searching range. It is indicated that the method proposed in this paper is superior to the existing methods on the premise of guaranteeing the stability of the filtering range, as shown by experimental comparisons with many traditional methods based on GPS data. This method has high application values in many fields such as the vehicle navigations and large-scale GPS data processing because it can further reduce the searching time by controlling the searching range effectively.
