The purpose of this study is to analyze characteristics of driver behavior during unexpected traffic emergency situations such as sudden unintended acceleration or brake system failure by analyzing their pedal behaviors. For this purpose it developed a test vehicle and a reproduction test scenario to create an unexpected situation. The reproduction test consisted of scenarios of sudden unexpected acceleration of vehicle, brake booster malfunction and jammed throttle pedal. Finally, we conducted the test with 80 driver lisence holders composed of female drivers and male drivers with less than 2 years of experience. The characteristics of driver behavior in normal state and expected and unexpected emergency situations were analyzed by using pedal angular velocity and effort, and camcorder recordings. The vehicle and scenario were used to conduct driver‘s pedal effort analysis and the findings will be used to create a smart safety system that recognizes and responds to drivers‘ behaviors.
