Choi, J.-S. Kim, H.-S. Shin, Y.-H. Choi, M.-H. Chung, S.-C. Min, B.-C. Tack, G.-R.

International Journal of Occupational Safety and Ergonomics

2015 Vol. 21, No. 1 111--117

Driving is directly controlled by the driver's movement. This study tried to compare differences in gender and headway distances between the DRIVING phase and the SUDDEN STOP phase by using subjects’ movement during driving in the simulator. To quantify subjects’ movement, the jerk cost function (JC[...]
