Analysis of Driver Brake Behavior Under Critical Cut-in Scenarios

Analysis of driver brake behavior parameters under critical cui-in scenarios is conducted based on naturalistic driving data collected in Shanghai, China. Time headway (THW) when brake initiation is chosen to evaluate driver's timing of brake initiation. Average brake pressure change rate and maximum brake jerk are to evaluate driver brake response speed, average deceleration is to evaluate the effect of driver brake maneuver, maximum deceleration is to evaluate driver's maximum brake strength. Effects of different factors on driver brake behavior parameters are analyzed by using one-way analysis of variance and linear regression analysis. Driver brake behavior parameters in this tudy are important for the development of longitudinal control systems of automated vehicles which are suitable for Chinese people.
