A multilane highway (three lanes in each direction) is on level terrain. The free flow speed has been measured at 50mph. The peak-hour directional volume is 1500 vehicles with 10% heavy vehicles, and PHF is 0.9. If the proportion of vehicles types and peak-hour factor remains constant, how many vehicles can be added to the directional volume before capacity is reached?
