specific Embodiment approach

[0068] figure 1 As shown, it is a structural diagram of a road traffic flow data quality control device (hereinafter referred to as: data quality control device) based on the numerical calculation theory designed according to the method of the present invention. Device, data storage device and data output device are composed of five parts. These five parts are related to each other and used in sequence according to the direction of data flow. The function of the device is realized by using Visual Basic language and ACCESS database, in which the data identification device and data correction device are the core of the device. Its operation process is as follows: when the raw data to be analyzed is prepared, set the parameters of the database through the data reading device, specify the type of data to be read, and read the raw data into the data reading device; the data reading device is connected to the data identification The device, after successfully reading in the data,...

Abstract

A control method of data quality includes carrying out data classification division based on judgement rules designed upon total comparison method, threshold theory and traffic flow theory; then utilizing figure calculation theory to revise the data. The designed device for the method consists of fetching device, identifying device, revising device, storing device and outputting device for data.

Description

technical field [0001] The present invention relates to a method and device for quality control of road traffic flow data, more specifically, a method and device for quality control of road traffic flow data using numerical calculation theory. This method not only improves the utilization rate of the correct data used as the basis for correction, but also does not require a large amount of historical data as a premise, which improves the convenience of data quality control work. Background technique [0002] Due to the failure of transmission equipment, road traffic conditions and abnormal environmental factors, the collected road traffic flow data will inevitably be wrong, lost or shifted at the time of collection. In order to accurately reflect the actual traffic conditions and meet the data application needs of users, it is necessary to control the quality of the original data, improve the accuracy of the overall data, and provide a good data foundation for data applicati...
