Correlation Analysis Of Data Mining And Its Application In Road Traffic Accidents

In recent years,with the increase of traffic volume in our country,the area of road traffic safety has been greatly challenged.More and more traffic accidents and accidents have become the urgent concern of road traffic departments and even the society.Through scientific analysis and digging the inner link between traffic accident data,find out the accident data hidden potential regularity in different properties,which provide Suggestions for the management of the relevant departments of the decision-making reference and theory,technical support is of great significance.Based on the theoretical knowledge of data mining,this paper USES the Apriori algorithm of correlation analysis to conduct data mining research on the Weka platform.In order to find the correlation between data of road traffic accident,the useful conclusion can be effectively prevented or avoided.The work is as follows:Firstly,summarize the research results obtained by predecessors in this field and analyze the problems still unresolved and further research direction.This paper introduces the knowledge background and relevant theories of data mining,introduces the basic idea of correlation analysis,relevant concepts and the classic Apriori algorithm.Secondly,to improve and optimize the classic Apriori algorithm for the complex and multidimensional data of the accident case database;the data is preprocessed,formalized and defined.Finally,a star model is adopted to construct the data attributes of road traffic accidents.Thirdly,several main application platforms for Apriori algorithm are applied,and data mining experiments are conducted using Weka tools.By loading the database,data processing,and a series of operations of the related panel,the mining experiment of road traffic accident data is completed and the result is analyzed.Fourthly,summarize and summarize the research work of this paper,and point out the research direction and key issues in the next step.This paper using the optimized Apriori algorithm to obtain good results in the data mining experiment on the Weka platform,and preliminarily achieves the basic purpose of the thesis research.
