$(10$ points$)$ Consider the example I showed bellows. A single, one$-$directional bus loop

serves travelers between three zones. The modelers inform you that the estimated direct

demand model is $D=D_0{t}^{0\mathrm{.}0638}{p}^{-0\mathrm{.}41},$ where $t=$ travel time $($min$),$ and $p=$ fare price $($$$),$

and demand is in passengers$/$hr$.$

Question: If a flat fare of $$3$ is currently in operation, and travelers for each OD pair are

assigned onto this loop on each link needed to get them from O to D$,$ determine the

elasticities of the link flows with respect to the fare price.
