Fratar method excel
WebFratar method is developed based on some main assumptions. First assumption is the future trip distribution of origin zone is comparable to the existing trip distribution of origin zone, then the second assumption prediction of the future trip distribution can be modified by the value of the growth rate of destination zone (Tamin 2000).

Web2.3 Fratar Method This method was used to compare the projection results to the calibrated gravity model. This model is similar to the uniform growth factor method, but takes into account the effect of distribution growth. The study has three general phases, namely: (1) acquiring O-D data, (2) calibrating the gravity Webthe results of a research project designed to evaluate on a common basis the fratar, gravity, intervening opportunities and competing opportunities trip distribution procedures are reported. each of the procedures was calibrated using the 1948 washington, d. c., o-d survey travel data as a base. ... various methods evaluate the accuracy of the ...
