Abstract: In this paper, we investigate driver braking behaviour under near-crash scenarios in one district of China. Real traffic scenarios were first collected using video drive recorder and these scenarios were screened and classified and then six typical types of near-crash scenarios were obtained. Then by processing the video images and analysing the velocity curves, driver braking behaviour under these six typical types of scenarios, especially the scenarios of 'following vehicle approaching a decelerating lead vehicle', was extracted and analysed. Finally, the driver brake reaction time, average deceleration during the emergency braking phase and the timing of emergency braking initiation were obtained. The results obtained in the paper can be used in the development of advanced driver assistance systems compatible with special Chinese traffic conditions.

Keywords: vehicle safety; advanced driver assistance systems; driver braking; driver behaviour; braking behaviour; near-crash scenarios; driver reaction time; brake reaction time; emergency braking; China; image processing; velocity curves; average deceleration.
