基于公路路网属性及缓冲区分析的农村公路变更表生成方法

Rural Road Change Table Generation Method Based on Highway Road Network Attribute and Buffer Analysis

针对交通统计领域中现有农村公路变更表生成方法需要大量人工核查、效率低的问题,基于路网属性及缓冲区分析对不同年份路网进行相似性评价,进而确定变更类型,根据实际需要只对相似性评价中参数阈值附近的路网进行人工核查,从而极大提高农村公路变更表的生成效率及准确性。以某省两年路网数据为例生成农村公路变更表,结果表明:本文提出的算法在最大限度减少人工核查量的前提下,显著提高农村公路变更表的生成效率。

For the existing rural road change table generation method in the field of traffic statistics, a large number of manual verification and low efficiency are needed. Based on the road network attributes and buffer analysis, the similarity evaluation of the road network in different years is carried out, and then the type of change is determined. According to actual needs, the road network near the parameter threshold in the similarity evaluation is manually checked, which greatly improves the efficiency and accuracy of the rural road change table. Taking the two-year road network data of a province as an example, the rural road change table is generated. The results show that the proposed algorithm can significantly improve the efficiency of rural road change table generation under the premise of minimizing the amount of manual verification.
