Abstract(in English)	With the increasing popularity of smart-phone,3G networks are currently overloaded with mobile data traffic. Due to this explosion of data traffic, communication quality deteriorates and communication failure occurs. To solve this problem, there have been proposed Wi-Fi offloading methods to offload mobile data traffic to WiFi network. However, there is a problem that outdoor mobile users like a waking pedestrian cannot offload mobile data, while they are out of Wi-Fi access area. In this paper, we propose a new WiFi offloading method which uses the vehicle passing near the user as a relay node. In addition, we focus on the fact that contact duration between vehicles and pedestrians is likely to be longer near the intersection. In order to increase the probability of successful data reception at a mobile user from the Internet, we propose amethod which selects a vehicle with a higher probability of encountering the mobile user.
