    When engineers build transportation forecasting models, the traditional process involves four steps:

    1. Trip Generation – predicts the number of trips originating in or destined for a particular traffic analysis zone
    2. Trip Distribution – matches tripmakers’ origins and destinations to develop a “trip table”, a matrix that displays the number of trips going from each origin to each destination. Historically, this component has been the least developed component of the transportation planning model.
    3. Mode Choice – analysis allows the modeler to determine what mode of transport will be used, and what modal share results
    4. Route Assignment – concerns the selection of routes (alternative called paths) between origins and destinations in transportation networks

    Once the engineer has complete these steps, they can build an invaluable forecast to guide policy, planning, and infrastructure development surrounding our transportation systems. Read More
