Abstract
ITS technologies are expected to be applied to not only VICS and ETC, but also vehicular safety systems. The vehicular safety system supports driver's cognition and reduces traffic accidents. To test the effectiveness of the systems by simulation, the coordination of multiple simulators such as a radio propagation simulator, a network simulator, and a traffic simulator is needed. And in the traffic simulator, the cognitive process of each driver should be modeled precisely. This paper describes the overview of ITS integrated simulator and improvement of the microscopic traffic simulator considering driver's visual cognition.
