Abstract
Based on accident realities in Japan, the necessity of vehicle infrastructure cooperative systems is explained at the introduction. The systems transmit information of traffic control (traffic signal and sign, etc.) and the event out of sight, which are difficult for the autonomous systems of vehicles to grasp. The systems attempt to decrease the accident risk by disseminating information and warning to drivers, and providing intervention control to vehicles. After the outline of the function and the assumed installation location are introduced, the outline of the field verification test scheduled in Aichi Prefecture in 2006 and 2007 for development of the systems is explained in this paper.
