Effect of road hump on driving comfort and safety of vehicles

On the base of analyzing the speed-control principle of road hump,the influence of the configuration dimensions of road hump on the driving comfort and the safety of vehicles is tested,the relations of body acceleration and axel acceleration with velocity while vehicle's passing through the road humps with different configuration dimensions are studied.The results show that: the height of road hump has a direct ratio to the control-speed,the height of road hump has inverse ratio to the control-speed;when the control speed is less than 40 km/h,400~500 mm width of road hump(with 40~50 mm height) can get good speed-control effects;when the control speed is less than 60 km/h,500~600 mm width of road bump(with 30~40 mm height) can acquire good speed-control results.1 tab,7 figs,10 refs.
