An Experimental Study on the Driver Workload of Telematics Service

Recently, diffusion of Telematics service and explosive increase of using in-vehicle display device such as CNS(Car Navigation System) are becoming the new causes of traffic accidents during driving. This is caused by 'Inattention' from increase of driver's mental workload while he/she is driving. It is the real situation that many countries including Japan are considering a control of In-vehicle device during driving through legislation. This research is studied about the effect of information system at voice or display unit on drivers through the Driver Eye Movement Analysis and measurement of performance ability. The experiment is carried out in the driving simulator environment, and the result presents through the comparative analysis of the driver's visual field via the gaze tracking device and average of correct-answer rates in addition arithmetic performance.
