Front blind spot crashes in Hong Kong.

In 2012-2014, our laboratory had investigated a total of 9 suspected front blind spot crashes, in which the medium and heavy goods vehicles pulled away from rest and rolled over the pedestrians, who were crossing immediately in front of the vehicles. The drivers alleged that they did not see any pedestrians through the windscreens or the front blind spot mirrors. Forensic assessment of the goods vehicles revealed the existence of front blind spot zones in 3 out of these 9 accident vehicles, which were attributed to the poor mirror adjustments or even the absence of a front blind spot mirror altogether.

Validation of pedestrian throw equations by video footage of real life pedestrian/vehicle collisions.

A total of 11 real life vehicle/pedestrian collisions in 2012-2014 were captured by CCTV cameras/car cameras in Hong Kong. Some of the footage was recorded in HD format at 30 frames per second, enabling accurate determinations of impact speeds with pedestrians, exact points of impacts and final rest positions of pedestrians as well as kinematics of the collisions. The calculated impact speeds from footage analysis were used to validate the published empirical and semi-empirical pedestrian throw equations.
