Abstract
In this paper, the affect of using smartphone by young driver is experimentally verified. Five participants drove the high way with the driving simulator in case of using smartphone and not using smartphone. On the driving, leading vehicle suddenly decelerated and we verify the response time between the time of sudden deceleration and the time of participants’ pressing the brake pedal. In addition that, we investigated the data of vehicle, such as velocity, steering angle and brake stroke. As a result, drivers using smartphone on driving tend to be able to control steering but not to control brake pedal well. The time between sudden deceleration and participants’ pressing the brake pedal of seemed to be delay more than that of beginners when they use smartphone. From the point of risk feeling, the drivers who get used to driving feel risk when they use smartphone on driving more than beginners.
