The Word version of the book on HDM-4's RUE modelling.

Comprehensive book on the modelling of road user and environmental effects. It covers all aspects from vehcile operating costs to emissins. The models presented here formed the basis for the modelling in HDM-4, although the software does not fully implement the models.

The NZVOC Model is used by Transfund New Zealand to prepare tables of vehicle operating costs for their Project Evaluation Manual. Two projects were conducted to update the costs and develop a new version of the NZVOC Model, one in 1999 and a second in 2001-2003. The NZVOC model contains enhanced VOC relationships and formed the basis for the HDM-4 RUE model.
