Data Cleaning Technique of Road Safety Information Based on ATMS
Wei Cheng · Journal of Transport Information and Safety · 2012
In ATMS(Advanced Traffic Management System),information is the most core content.The various functions of the system are based on information in the application as the center spread.In order to guarantee the quality of the data used in ATMS,to improve the utilization of information resources but reduce the loss of information resources cycle,to improve the processing efficiency of the system but reduce the overhead of the system,this paper uses the data clean technology to establish a data clean framework,which has suited the ATMS's demand of the information data cleaning and realized the high-efficiency optimized processing of the road safety message data gathered currently.As a result,The data input into the ATMS can ensure the system make hign-quality decisions.Thus,the system's operating efficiency can be promoted.
