Summary:The invention discloses a road network checking method based on floating car track big data. The method comprises the steps of data preparation, data preprocessing, road network checking method, experiment and analysis. Experimental verification is carried out on a research experimental area through a data checking method based on grid indexes and line segment credibility, generated results are analyzed, and a program can semi-automatically check a road network by utilizing floating car track big data; the method is advantaged in that an expected target is realized, the road network verification result has relatively high precision, the method can be applied to actual verification of the road network, semi-automatic operation of road network verification is realized after the user interacts with input threshold data, manual verification cost is reduced, and verification efficiency is improved. 本发明公开了一种基于浮动车轨迹大数据的路网核查方法，包括数据准备、数据预处理、路网核查方法、实验与分析，通过基于格网索引与线段可信度的数据核查方法对研究实验区域进行实验验证，将生成结果进行分析，程序能够半自动地实现利用浮动车轨迹大数据
