Abstract
In the design of bridge, the designer's subjectivity enters into the form of bridge, willynilly.
Accordingly, in this paper, a means giving the objective data in examination of the form is proposed from a standpoint of application of PSYCHOMETRICAL TECHNIQUE. This technique includes “Method of Paired Comparisons”, “Method of Rank Order” and “Method of Successive Categories”.
It is thought that these methods are not only the form but also applicable for the colour and scene of bridge.
