Abstract (in Japanese) (See Japanese page) 
(in English) Traffic congestion is a social problem causing both economic and time loss. Such traffic congestion mainly comes from selfish routing where users or navigation software aims to minimize their own travel time. It is hard to change such users’ sense of values because the selfish routing is rational decision by individual users. In this paper, we propose a scheme to achieve social optimum route assignment under users’ selfish routing, with the help of server’s notification of appropriate traffic information. Through numerical evaluations under a grid-like road network, we confirm that the proposed scheme can achieve the same performance as the optimal routing. We further demonstrate that the proposed scheme improves the average travel time by 27.2% compared with the conventional selfish routing, through numerical evaluations under a real road network in Nagoya city, Japan.
