Abstract: ITS demand analysis is one of the fundamental steps of ITS plan. Primary problems in the step are analyzed, then the application of fuzzy cluster analysis in analyzing ITS demand is studied, and the corresponding VBA assistant program is compiled. The practicability of the method and the program are validated by their application in the analysis about advanced transportation management field of the Beijing Olympic ITS plan
