Figure $1$ shows a sketch of a proposed urban freeway $($east bound only$).$ Determine the number

of lanes of two mainline sections $($i$.$e$.,$ section A & B$)$ in the figure. The Directional Design Hour

Volume $($DDHV$)$ and the length of each section are provided in Figure $1.$

Other necessary inputs are presented in Table $1$&$2.$ Show all your calculations and suggest the

most appropriate number of lanes for each section. $($Hint: $1)$ use necessary information only. $2)$
