APPLICATION OF THE DECISION TREE TECHNIQUE IN THE ANALYSIS OF TRAFFIC ACCIDENTS

Abstract

The aim of the research is to examine the possibility of applying Weka software in the process of analysing traffic accidents that occurred in the territory of the Republic of Serbia. During the analysis, the J48 algorithm of the decision tree technique was applied. The database of traffic accidents from 2019, in which a total of 35,956 accidents were recorded, was taken over from the portal of open resources. The analysis of the same in Weka software, and the application of the mentioned algorithm, it came to the results, which showed that a large number of instances of the downloaded database were incorrectly classified. The reason for this is the inadequately standardized database model used in the research. In conclusion, the dominant thesis is that, in order to obtain useful information from databases, they need to have a clear and logical structure, as well as standardized elements for entering the value of attributes.
