* Saturation flow (S) must be corrected for effect of gradient, turning radius, left-turn and right-

turn (whichever required).

* Assume turning radius for this intersection is between 10 15 m.

Calculation of Saturation Flow, S

Y = y1 + y2 + y3 = Ymax

(Note: Y must be 0.85 or below, in order to proceed with calculations.)

Y = 0.29 + 0.44 + 0.07 = 0.80
