Revised vehicle operating cost models for Australia

Updated vehicle operating cost (VOC) models are an important input to the economic evaluation of road projects. This paper presents revised VOC models for Australia updated as part of the National Guidelines for Transport System Management (NGTSM) review of parameter values. The paper first reviews the development of VOC models in Australia. It then outlines the methodology used to estimate revised rural (uninterrupted or free flow) models and urban (stop-start or interrupted flow) models. These are then available for modelling on the basis of different time periods, e.g. a.m. and p.m. peak periods, and day and night time off-peak periods, which provides a consistent approach to incorporating travel time and freight delay costs for general CBA with total RUC calculated using a common average travel speed/total link time. In the NGTSM, VOC models are specified for an extended set of 20 vehicle types, over different traffic and road conditions (using road roughness & speed as key variables depending on gradient, curvature and road width) and their basis and effect is illustrated herein. Payload is also incorporated into the models as a variable. Model coefficients have been re-estimated for the specified models, as well as outputs of the models in physical consumption units and monetary values for fuel consumption and for total VOC. Finally, the paper provides a set of recommendations for further development of VOC models in Australia.
