Analysis of Driver's Subjective Risk Level at Pedestrian Appearance (Second Report)~Analysis by Actual Vehicle Test
Published October 12, 2011 by Society of Automotive Engineers of Japan in Japan
In this paper, several of driver's reactions are collected by actual vehicle test when he/she acknowledges a pedestrian who suddenly pops out into the road. The influential factors to the hiyari-hatto level is considered based on collision timing, variation of reaction time to release the acceleration pedal, and variation of driver's subjective risk level. The latter two are collected in expected/unexpected scene. Time to collision, collision timing, and unexpectedness are evaluated as the important influential factors in the first report.
