"To wrap up our discussion on growth factor models, let’s look at the actual mathematical engine behind the Fratar Method. At first glance, the formula looks complex, but it’s essentially a double-proportional balancing act. The goal is to estimate T {i j}—the future trips between two zones—based on how much both the origin and the destination are expected to grow. Let's break down the components: First, we have the term (t_i and G_i). This represents the total future trip generation for the ori
