Abstract

This project focused on changes in drivers’ heart rates while braking, as an approach to understanding driving behavior. Using tests designed to model a variety of braking conditions, it was observed that driver psychological states while braking are displayed in the form of changes in heart rate. In a test where an obstacle darts out from the side of the road, driver heart rates were observed to increase suddenly. On the other hand, a test where the vehicle comes to a halt at a stop line showed the heart rate gradually slowing before the vehicle stopped. It was thus inferred that changes in heart rate take on a distinctive pattern in response to braking behavior. In this light, an index formula was proposed that uses the magnitude of the response in heart rate acceleration during braking to determine whether an instance of braking behavior represented panic braking.
