Abstract

Data mining is the process of extraction of hidden predictive information from large databases and expressing them in a simple and meaningful manner. This paper explains the use of Fuzzy logic as a data mining process to generate decision trees from a pavement (road) database obtained from Ohio Department of Transportation containing historical pavement information from 1985 to 2006. Generally there are many attributes in the pavement database and often it is a complicated process to develop a mathematical model to classify the data. This study demonstrates the use of fuzzy logic to generate decision tree to classify the pavement data. Further, the fuzzy decision tree is then converted to fuzzy rules. These fuzzy rules will assist decision-making process for selecting a particular type of repair on a pavement based on its current condition. The fuzzy decision tree induction method used is based on minimizing the measure of classification ambiguity for different attributes. These models overcome the sharp boundary problems, providing soft controller surface and good accuracy dealing with continuous attributes and prediction problems. This method was compared with common logistic regression model for predicting the pavement treatment. The results show that the fuzzy decision method outperforms the logistic regression model by 10%. The fuzzy decision tree method generates the rules, which gives the better understanding of the relationship between the parameters and the pavement treatment prediction.
