One segment of a two-lane, two-way rural highway is on rolling terrain and currently operates at maximum level of service C conditions. The annual growth rate of traffic on this segment of road is about 5%, and studies shown that it will continue to grow at this rate for the rest of this decade. Assuming a K factor (design hour factor) for this segment of road = 0.13, determine in how many years will the number of lanes have to be increased if the level of service must not be worse than D?
