碩士 === 國立東華大學 === 資訊工程學系 === 102 === In recent years, vigorous development of network applications has gradually changed from the traditional network applications to the wireless mobile network applications and services. It forms the vehicle network (VANET) by connecting the wireless network, using the moving vehicles as a platform in the vehicle environment. It deploys an intelligent transport system (ITS) to integrate the information of vehicle and road for improving the safety and efficiency of traffic. The traditional vehicle network system contains two important communication modules, namely the wireless transmission device (OBU) which is installed in vehicles and roadside base station. OBU likes a computer, is responsible for executing the applications and transferring, receiving data. It integrates with sensors, such as event data recorder, GPS, and so on, for receiving its traffic data and finally interacts with users by the input/output interface. However, the deployment cost is expensive. If you can find an alternative wireless transmission device which has lower cost and can also achieve the same ability, then it will be welcome. In this study, we propose a system architecture which composes of three layers. We use the very popular smart phones as our wireless transmission devices, which provide its sensors, video capture, GPS, and so on, for collecting the vehicle information nearby and then stored in the database. It allows users to exchange the vehicle information near their area, and then can obtain the traffic situation from afar in order to achieve the traffic safety. Keywords: VANET, ITS, OBU, GPS
