= H R h -x +x 2L Figure 1: Circular hump profile Fig. 1 shows the circular road hump profile where the radius R in meter and the length and the height of the hump. 2 = 2 + ( − ) 2 = 2 + 2 2 ℎ = √ 2 − 2 − ( − ) b) Trapezoidal Hump Fig. 2 shows the configuration of the trapezoidal hump. The trapezoidal hump is characterized by total length “L”, inclined length “L 1 ”, flat top length “L2”, and hump height “H”. Figure 2: Trapezoidal hump profile The hump height can be expressed as follow: ℎ = ⎩⎨ ⎧ 1 0 < < 1 1 < < ( 1 + 2 ) ( − ) 1 + 2 − ( 1 + 2 ) < < c) Cat-Eye Hump The cat-eye hump is arranged in a matrix configuration and distributed transversally to the roads. It is principally designed as a cushion or attention system. Fig. 3 shows the cat-eye hump configuration.
