AB - Factor analysis is broadly used for analyzing complex and voluminous flow data such as travel to work data. The purpose of this paper is to review the effectiveness of the factor analysis for flow data in methodological aspect. By factor analysis, destinations (origins) can be regionalized based on the similarity of the variables, and the flow between the grouped destinations (origins) and their main origins (destinations) can be identified. Interpretation of the main destinations and origins identified in this process have to be done with caution and the fact that significant flows in absolute value might be hidden has to be considered when the standard score and the correlation of variables are used. If the orthogonal rotation of factor is done in case factors are correlated, it makes the interpretation of the analysis more complicated. There are attempts to zone functional regions according to the result of factor analysis; however factor analysis does not have adequate logical basis for identifying functional regions when functional region’s conception reflects regionalization by minimizing inter-flow and maximizing the intra-flow.
