Validity evaluation method of vehicle overspeed detection data

Abstract

The invention provides a vehicle over-speed detection data effectiveness evaluation method. An over-speed detection data uploaded by vehicle speed detection equipment which has a license plate recognition function is endowed with an over-speed risk index I0, consistency detection, credit detection and correlation detection are conducted on a speed measurement value based on the basis of conducting vehicle speed threshold value detection on the over-speed detection data, finally an over-speed risk index I is determined, according to the detection result, a risk index is determined, and the effectiveness of the over-speed data is further evaluated. According to the vehicle over-speed detection data effectiveness evaluation method, with single piece of detection data being an analysis object, fine quality detection on front-end original speed measurement data can be achieved, through the speed measurement risk index, data effectiveness analysis is conducted quantitatively, abnormal detection records can be screened out, and through multiple recorded risk indexes, abnormal conditions of corresponding equipment can also be counted and analyzed.

Description

technical field [0001] The invention relates to a method for evaluating the validity of vehicle overspeed detection data. Background technique [0002] At present, the bayonet equipment that realizes the detection of vehicle speed is widely used in the control of road traffic. The automatic identification and investigation of speeding vehicles greatly reduces the intensity of on-site law enforcement by the traffic police department, and effectively regulates the order of road traffic operation to ensure traffic safety. However, the roadside detection equipment in the application is affected by various internal and external factors, such as network transmission, road traffic conditions, weather environment, etc., and there may be data abnormalities, especially due to abnormal speed measurement, which may cause errors in vehicle violations and penalties, which will affect the effectiveness of off-site law enforcement. . Therefore, an effective data quality detection method is...

Problems solved by technology

[0003] At present, there are limited ways to detect the speed of single vehicles. For example, the speed detection of floating vehicles based on GPS positioning is difficult to achieve the full sample detection of road network vehicles. At the same time, it is subject to the difficulty of data sharing among various traffic management departments. It is difficult to judge the validity of the speed detection value by obtaining detection data from other data sources for multi-source data analysis.

Patent 2016101607487 proposes a data quality detection method for bayonet detection equipment, in which the quality detection of a single piece of speed measurement data is based on the vehicle speed threshold at the location. This method can detect data with significantly abnormal speeds, but the sensitivity of abnormal recognition needs to be improved
