This New Zealand Transport Agency 2009 report describes the outcomes of a study commissioned by the NZ Transport Agency (NZTA) to inform local authorities about the costs and benefits of transport modes. The aim of the study has been to provide general advice on the relative cost and benefits of alternatives with a focus on passenger transport in urban areas.

The report looks at issues decision makers face in estimating costs and sets out an approach to providing estimates. This approach provides parameter values such as cost per vehicle kilometre, which can then be applied to the number of vehicles and the distance they travel, so readers may tailor comparisons to their own situation.
