ABSTRACT

In order to investigate driver's behavior, including eye movement, vehicle operation and vehicle trajectory, a driving simulator and an eye tracking system were used in this experiment. Fig. 1 shows the experimental set-up and a schematic view of the apparatus. A driving simulator with a 6-axis motion base system (Honda Motor DA1102) was used to simulate driving an automatic transmission vehicle. Table 1 shows the specifications of the DA-1102. The simulator is controlled by a network of computers which also generate images from the driver's point of view, as well as those in the side-view and rear-view mirrors, car dynamics (such as steering and braking motions), and traffic scenarios. Ethernet-linked computers acquired a log of input and output variables (such as a steering, accelerator, brakes, the position of the car and speed). This data was acquired every lOmsec. Several different scenarios were simulated in the driving simulator, such as urban roads and highways and so on. The images and car dynamics were generated in real time based on the participant's maneuvering in the simulator. The instruments on the dashboard, steering wheel, gearshift, side brake, accelerator, and brake pedal were positioned in a manner similar to that in a real car, as shown in Fig. 2.
