Whole-View Driving Simulator For Measuring Driving Behavior In Town Environment

A hi-fidelity driving simulator with the 300 degree screen and an actual vehicle cabin on hexapod motion platform has been developed in order to measure driving behavior, including visual behavior, in town environment. For measuring the driving behavior, various driving parameters were recorded. The eye glancing direction was detected by combining the eyetracking system and the head-tracking system. The eye glancing direction on the ground coordinates system was computed by transferring eye-movement data onto the eye-tracking screen coordinates. An experiment with ten subjects was conducted to investigate the characteristics of driving behavior for the repeated drive for about 5 km in the town with several left and right turns.The eye glancing behavior while turning left at intersections was analyzed in this paper. The tragectory of the eye glancing points differs driver by driver, but the tragectory showed a certain goemetrical form. This suggests that each driver follows imaginary leading line to perform the turning maneuver.
