| Abstract(in English) | Existing Traffic Information Systems including VICS (Vehicle Information and Communication System) commonly provide traffic information of roads by means of simple texts or computer graphics. However, in these systems, the variety of congestion situations in real environments are represented using limited number of congestion levels. Thus, it is difficult for drivers to understand the actual traffic condition from such limited information. In this paper, for providing drivers more direct information about traffic conditions, we propose a system for collection and delivery of video data on congested roads based on participatory sensing using smart phones. A large amount of bandwidth is consumed by sending video data over 30 networks, the system needs to deliver the most appropriate video data to the drivers by considering the constraints on 3G bandwidth. We define the utility function which models driver's benefit of viewing congestion videos based on the difference of congestion degrees be tween the delivered video and the current traffic condition, latency between the transmission time of the video request and received time of video data, etc. Our system maximizes the value of the utility function subject to the constraints on 3G bandwidth to achieve the efficient collection and delivery of congestion videos. |
