Flow has been responsible for carrying out peer reviews of all of the Government Roads of National Significance (RONS), with all covering transport modelling and toll modelling, and some extending to economic analysis.

This work demonstrates our high standing within the NZ Transport Agency, as we were trusted to review all of the RONS, to advise on emerging good practice, and in some cases to “call out” a need for improvements in the evaluations.  Also, in some cases we provided an independent view of specific issues.

This work has increased our understanding of the roles and functions of the State Highways in each region, and the effects of proposed investments on the adjacent parts of the strategic and local road networks and on public transport. It has also increased our understanding of the current assumptions and the strengths and limitations of each of the regional transport models.
