[0084] see figure 1 , is a flow chart of a method for cleaning and repairing traffic flow data based on time-space sequences proposed by the present invention.
[0085] Such as figure 1 As shown, the present invention proposes a method for cleaning and repairing traffic flow data based on time-space sequences, including the following steps:
[0086] Step 100, storing the traffic flow information received in real time in the dirty data storage module in a fixed format;
[0087] Step 200, using the data cleaning module to clean the traffic flow information in the dirty data storage module to obtain cleaned data;
[0088] Step 300, using the data repair module to model the cleaned data and perform data repair to obtain repair data;
[0089] Step 400, storing repair data in a clean data storage module.
[0090] Due to abnormal environmental factors, equipment failure and other reasons, the data obtained by the same detector has phenomena such as invalidity, redundancy, error l...
