$6\mathrm{.}32$ A six$-$lane multilane highway $($three lanes in each direction$)$ currently operates at maximum LOS C conditions. The measured FFS is $55$ mi$/$h$.$ The highway is on rolling terrain with $14\%$ SUTs and $6\%\text{'}$TTs$,$ and the peak$-$hour factor is $0\mathrm{.}92.$ If $17\%$ of all directional traffic occurs during the peak hour, determine the total directional traffic volume.
