S181013 Collision Avoidance Behavior of Drivers against Sudden Appearing Vehicle from the Side

Abstract

This paper analyzes the driver's collision avoidance behavior in an emergency. Experiments, in which participants drove a test vehicle at around 40km/h and a dummy vehicle suddenly appeared from the side, were conducted on a proving ground. Two out of 56 participants could not respond to the emergency situation, that is, they did not apply the brakes. The driver behaviors were analyzed, for example, it was revealed that average brake response time was 0.45 seconds and average deceleration after braking was 7.0 m/s^2.
