The human centered ITS view aid system is a driver-adaptive driving assistance system aiming at helpful, appropriate and not annoying display of information and warning for any driver. It consists of on-board sensing systems for road surface and inter-vehicle spacing, driver monitoring systems for eye closing and eye casting, inter-vehicle communications, and an information and warning display system. The road surface wet condition is detected with the polarization of the reflection by the machine vision. The driver monitoring system is based on the machine vision. One of the features of the human centered ITS view aid system is that the information and warning display is designed to be adaptive to the characteristics of a driver including the age and the consciousness. The three-year project supported by Japanese Ministry of Economics, Trade, and Industry was started in 2001, and the concept and the precursor studies are described in this paper.
