A study on driver's workload of telematics using a driving simulator: A comparison among information modalities

초록

Recently, diffusion of telematics services and an explosive increase of in-vehicle display devices, such as Car Navigation Systems (CNSs), are becoming the new causes of traffic accidents. This is due to 'inattention' caused by an increase in the driver's mental workload while he/she is driving. This situation has lead many countries to consider controlling the use of in-vehicle devices while driving through legislation. This research studies the effect of voice or display information systems on drivers through the Driver Eye Movement Analysis and the measurement of response ability. The experiment is carried out in a driving simulator and the results are presented through the comparative analysis of the driver's visual field via the gaze tracking device and the average of correct answer rates for arithmetic problems.
