6.11 A multilane highway (two lanes in eachdirection) is on level terrain. The free-flow speed hasbeen measured at 45 mlh. The peak-hour directionaltraffic flow is 1300 vehicles with 6% large trucks andbuses and 2% recreational vehicles (f : 0.95). If thepeak-hour factor is 0.85, determine the highway'slevel olservice.
