c$.$ There are uneven growth rates for both trip productions and attractions across TAZs.

Table $6\mathrm{.}5$ shows the expected trip production and attraction for each TAZ in $2025.$ Use$|$

the Doubly$-$Constrained Growth Factor method $($also called Fratar method$)$ to estimate

an OD matrix for $2025.$ Please show your results in Table $6-6.$
