Commercial vehicle usage and forecasting: stage 2: national freight traffic

The purpose of the research was to assist in regional transport modelling and long-term road planning by defining the amount of commercial traffic on the major highways in New Zealand, giving trip numbers at the boundaries of each region, and the likely destination and routes taken by these trips within the region. The research proposal was based on the project being delivered in two stages. The literature review included research on national freight models by overseas researchers, and papers on New Zealand freight movement. Information and statistics from the literature review were used to derive appropriate inputs to the models as required. The three models are essentially three ways of looking at the same problem. Three matrices were derived from each model, giving a robust approach and a means of calibrating the results. The variability of the results between the three models illustrates that taking only one overall approach is probably not the correct strategy for developing a national interregional freight model. A combination of gravity modelling and IO analysis is more likely to yield a representative model of inter-regional commercial vehicle flows. (a)
