The information and resources on this page help to explain the Transport Agency’s Investment Assessment Framework (IAF) for the 2018–21 National Land Transport Programme (NLTP) and our approach around making investment decisions.
While the examples of investment proposals listed below are similar to those made by our transport sector partners, they are fictitious examples. To get the best understanding of how we might apply the IAF, please also read the IAF. You may also find it helpful to refer to the results alignment criteria in the IAF which you will find on our website’s Planning and Investment Knowledge Base.
The IAF is the framework the Transport Agency uses to assess and prioritise projects and programmes for inclusion in the NLTP. It helps you to understand how your projects will be prioritised under the 2018–27 GPS and to frame-up Regional Land Transport Plans (RLTPs).
The Planning and Investment Knowledge Base has detailed information about the IAF and how different activity classes are assessed.
Learning modules on the IAF are available on the Transport Agency’s Learning Zone.
To request a login for Learning Zone, or for any other questions on the NLTP or the IAF, please email firstname.lastname@example.org
