Abstract
To evaluate a proper correlation coefficient with fuzzy data is an important topic in the transportation engineering, especially when the data illustrate uncertain, inconsistent, and incomplete type. In general, we use Pearson’s correlation coefficient to measure the correlation of data with real values. However, when the data are composed of fuzzy interval values, it is not feasible to use such a classical approach to determine the correlation coefficient. This study proposes the computation of fuzzy correlation coefficient with fuzzy interval data. Empirical studies are employed to explain the application for evaluating fuzzy correlation. More related practical phenomena can be explained using the application of fuzzy correlation.
