Webb) Synthetic Models / Interaction Models: The gravity model is included in this category. i) Gravity Model: This model originally generated from an analogy with Newton's gravitational law, which states that the attractive force between any two bodies is directly related to their masses and inversely related to the distance between them. WebThe most widely used formulation is still the gravity model. While studying traffic in Baltimore, Maryland, Alan Voorhees developed a mathematical formula to predict traffic patterns based on land use. This formula has been instrumental in the design of numerous transportation and public works projects around the world.
