value of acceleration / deceleration is shaped as the trapezoid; see Fig. A-20. In acceleration,
there are three regions with different acceleration values. At the beginning, the acceleration
increase linearly from 0 to the specific value A with a specific rate of acceleration K, this shows
the driving speed increase parabolically in this region. Then, the driving speed increases in a
constant acceleration in region b. And, in section c, the acceleration decelerates linearly to 0 with
the rate of deceleration K. So the acceleration of S-curve includes regions a, b and c. In
deceleration, as same as acceleration, the driving speed decelerate parabolically in three regions
d, e and f.
