| Abstract(in English) | Existing Traffic Information Systems commonly provide traffic information of roads by means of simple texts or computer graphics. In these systems, since the variety of congestion conditions in real environments are represented using limited number of congestion levels, it is difficult for drivers to understand the actual traffic condition from such limited information, In this paper, to provide more direct information about traffic conditions for drivers, we propose a system for collection and delivery of video data on congested roads based on vehicular participatory sensing using smarttphones. A large amount of bandwidth is consumed by sending and receiving video data over 3G networks, the system needs to deliver the most appropriate video data to the drivers by considering the constraints on 3G bandwidth. We define an utility function that models driver's benefit of viewing congestion videos from the difference in congestion degree between the delivered video and the current traffic condition, from the difference in time between a transmission of video request and a receipt of video data, etc. To achieve efficient collection and delivery of congestion videos, we propose an algorithm for maximizing the value of the utility function subject to the constraints on 3G bandwidth. From the simulation result, we confirmed that the proposed algorithm achieves about 10% higher value of the sum of the utility function than that of a simple algorithm. |
