Given the data below on three zones, use the gravity model to distribute the forecasted

trip productions and attractions among the three zones. Calibrate the model first using

the base$-$year data which requires the determination of a socioeconomic factor after the

first iteration which is equal to $(T_{i,}$ Observed $T_{ij}$ Calculated$)$ then complete a second

iteration using the socioeconomic factor in the calculations to assure your model equals

the base year trips. Then apply the model with the calculated socioeconomic factor to the

horizon year to determine the trips between zones. Continue with the gravity model until

the adjusted attraction factors converge upon $1\mathrm{.}0$ within a reasonable agreement $($within

$5\%).$ the complete base year observed trip data and the desired level of agreement, is provided in the picture attached. please confirm and provid the correct and full solution this is already my third time posting the same question. Please take it seriously.
