Outline of Final Research Achievements

We studied fundamental technologies of wireless network, for realizing advanced ITS (Intelligent Transport Systems) which can enhance our safety and economy, and further improve our daily lives, as follows;
1)In order to detect and to avoid pedestrian-vehicle collisions, we developed pedestrian positioning system with a sub-meter accuracy, using ultrasound / UWB distance measurement and DGPS. 2)For increasing capacity and diversification of transmission, applying cognitive radio technologies to ITS, we proposed dynamic resource utilization methods. 3)To enhance communication area and reliability, we proposed relay-assisted V2V technique with a sectorized-receiving and payload-combining relay station. 4)We studies a system architecture which enables, based on the context, well controlled communications in cross-layer-manner. 5)For performance evaluation of V2V communications in urban environments, we built an simulation system scalable to the size of area and to the number of vehicles.
