可升降减速带 / Liftable speed hump


No matter how slowly you drive when crossing a speed hump, your car still jolts, then how do you feel? what's the meaning of the speed hump, why do people still get jolted since the speed has gone down? In view of this, i designed this liftable speed hump, speed is detected by a speed measuring device, when speed is low, the hump will descend, the car can pass it smoothly. When speed is high, the hump will come up, playing a role of both blockers and warner, and next time when the driver passes a speed hump, he will drive slowly.
