交通流数据质量检验方法

交通流数据目前对于交通相关研究具有很重要的参考和使用价值。交通流数据质量检验可以保证从数据源所获得数据的正确性和完整性,并为数据的管理和应用提供可靠的数据基础。交通流数据常见问题分为数据缺失、数据无效和数据时间点问题三类,针对这些问题,本文提出了一种交通流数据检验与修复方法。以北京市交通流数据为例,对本方法进行了分析与验证。结果表明此方法具有很好的实际应用效果。

A Practical Method of Verifying Quality of Traffic Flow Data

The traffic flow data is very important and useful to the traffic research work.The Verifying Quality of Traffic Flow Data is to ensure the completeness and accuracy of the data obtained from the data source,and provides reliable data for the data management and application.Traffic flow data common problems divide into three issues:data lack,data invalid and data time problem.To solve these problems,this paper has proposed a method of examining and repairing traffic flow data.This method has been analyzed and proved with the traffic flow data of Beijing.The result indicates that this method has splendid ability of practical application.
