A freeway is to be designed to provide LOS C for the following conditions: design hourly volume of $5200ve\frac{h}{h}$ in one direction; PHF: $0\mathrm{.}8$ ; trucks: $8\%$; recreational vehicles: $2\%$; driver population: commuters and familiar drivers; right side lateral clearance: $5ft$; rolling terrain; total ramp density of $1\mathrm{.}2$ ramps per mile. Determine: whether six $($three in each direction$)12ft$ lanes are enough to provide LOS C$.$
