Evaluation of Driver Acceptability to In-Vehicle Traffic Light

Abstract

The in-vehicle traffic light is used to displays the traffic signal based on the information transmitted from the ground traffic signal using infrastructure-to-vehicle communication technology. However, while drivers need to observe the display to recognize the signal of the in-vehicle traffic light, it is necessary to measure the gaze motion to evaluate the safety. In this study, the effect of the mode of the in-vehicle traffic light and the methods to display the signal on drivers' behavior was evaluated by the operation of the drivers, the gaze motion, and the questionnaire in the experiments using the driving simulator.
