We have three motives to go on a journey to sightseeing spot: growing in knowledge, improving oneself and relaxing. This paper suggests a method of generating diverse drive plans on attractions by using paired comparisons on number of spots and trustworthiness of spots as attractions and paired comparisons on user three travelling motives. The method shows 2 day drive plans and accommodations to stay, and these plans are diversified by using immune algorithm. In case that number of spots is very important, the method suggests drive plans including many spots which are deeply-committed to user travelling motives. In case that trustworthiness of spots as attractions is very important, the method suggests drive plans including many superior spots in trustworthiness as attractions which are deeply-committed to user travelling motives. In this paper, the trustworthiness of spots as attractions is measured from number of blogs written about spot. I think that the method is valuable as an application of Kansei evaluation.
