Urban transportation system consists of multiple travel mode operated by many agents. Thus, improvement of transportation hub are required to achieve comfortable urban transportation network. This research focused on comfortable lightening environment of bus stop. We implemented outdoor experiment to examine the effect of the degree of illuminance and the color temperature of lightening around bus stop on comfortableness of users. 15 experimental condition, which were consisted by 5 illuminance conditions and 3 color temperature conditions were prepared. Participants of experiment were requested to answer questionnaire at experiment site.

As a result of experiment, respondents showed high sense of comfortable, sense of safety, visibility of the space, sense of calm and satisfaction at high illuminance conditions. Besides, they showed high sense of safety and calm at low color temperature conditions. These effects were significant at low illumination (5lx-30lx) experiment conditions. Results of implied that illuminance of comfortable bus stop are required more than 30lx. In the case of low illuminance (under 30 lx), low temperature color of lightening could make people comfortable.
