Study on ITS Detectors Traffic Flow Data Quality Control System
Zhu Li · Measurement & Control Technology · 2008
Traffic information is the foundation of the most intelligence transportation system(ITS) in data supporting,and provides continuous force for the whole system,therefore as the system raw material,its quality will directs influence overall system benefit.Taking the quality control subsystem of ITS flows data as the object,firstly,the structure of the overall frame which mainly included the malfunction data distinction model and the malfunction data revision model is analyzed,then the cooperation processing of traffic flow the data quality control is analyzed,and the loss data,an irregular time data,the unusual data distinction model and the revision model,as well as fault detector distinction and processing method are given.Finally,the design report and development of system are introduced,and obtains the good effect in the Shenzhen municipal transport simulation system.
