JUNE, 2000 ROAD DESIGN MANUAL (ENGLISH) 5-2(7)
operation of the left-turn maneuver outlined in Case IllB,see Figures 5-2.02F and G to obtain required sight
distances.
In designing for case IIIB or IIIC,figure 5-2.02G is used. The figure is based on a passenger car
design vehicle. The intersection sight distance needed for trucks is considerably bigger than that for P. The required
sight distances(d)may be computed using the formula d= 1.47V(J+ta). The time(ta)required to accelerate and
traverse the intersection(distance=S)may be obtained from figure 5-2.02D. Corrections for grades greater than+
3% must be made using the truck acceleration charts shown in Chapter 3. Designers should use the curvilinear
distance of S when applying cases IIIB and IIIC.
