Comparison of evaluation for the roadscape design of highway by civil engineers, architects and users

In recent years, the studies at the view point of roadscape design are done in the prosess of constructive planning of a new highway. This study examines the psychological evaluation for the shape of tunnel gate by semantic differential method. For the comparison of evaluation by architect, civil engineer and user, we did the questionnaire survey in 1993 for 427 persons. In case of tunnel gate, the arch type which is slender at the top gives a rhythmical and favourable impression to all people but the evaluation for the new type which has rings before the gate is differential.
