    Types Of Modal Split Models

    This section discusses various types of modal split models used to understand and forecast transportation choices.

    Learning Practice

  • 9.4.1

    Trip-End Modal Split Models

    Trip-end modal split models estimate mode choice based on personal characteristics and trip details, providing accurate short-term predictions but lacking responsiveness to policy changes.

    Learning Practice

  • 9.4.2

    Trip-Interchange Modal Split Models

    Trip-interchange modal split models apply modal choice analysis after the trip distribution stage, allowing for the inclusion of journey characteristics and policy implications.
