The objective of this research is to evaluate the attractiveness of internal spaces of Service Areas along Expressways. To achieve the objective, psychological surveys on twenty Service Areas are executed, using eight photos for Service Areas’ internal spaces as stimuli. Evaluations have four categories. First is to determine the ranking of twenty Areas. Second is to classify Areas’ absolute evaluation into attractive, non-attractive, and neither of each. Third is synthesized evaluation of ranking and absolute ones. Fourth is to count the number of people who note each stimulus as reason to judge Areas as attractive. As a result, most of Shin-Tomeis’ are attractive, the others are non-attractive by ranking. Difference of evaluations between Shin-Tomeis and the others are more than twice. By absolute and synthesized evaluations, differences between Shin-Tomeis and the others are more distinctive. By fourth, the more absolute evaluation is high, the more support levels of stimuli become higher. Difference of design concept between Shin-Tomei and other Expressways is considered to be the reason of differences of evaluation. In conclusion, degree of attractiveness level of internal spaces of Service areas were clearly distinguished into high and low evaluations. Also, areas of high evaluation have highly appreciated spaces.
