Problem $1$: $(2\mathrm{.}5$ Points$)$

Determine the LOS for the freeway during the worst $15$ minutes of the peak hour.

$-$ Eight lane freeway $($four lanes in each direction$)$

$-$ Lane width $11$ ft

$-$ Right$-$side lateral clearance $\backslash (=4\backslash$mathrm$\{$ft$\}\backslash )$

$-$ Peak hour, peak direction demand volume $\backslash (=8,500\backslash$mathrm$\{$veh$\}/\backslash$mathrm$\{$hr$\}\backslash )$

$-\backslash (\backslash$mathrm$\{$PHF$\}=0\mathrm{.}95\backslash )$

$-$ Traffic composition: $\backslash (6\backslash \%\backslash )$ trucks

$-$ TRD$=0\mathrm{.}67$

$-$ Level terrain

$-$ Facility operates under normal conditions and with commuter traffic
