This study examines the multimodal issues associated with adequacy, infrastructure investment, transport externalities and allied modal interactions. The overall conclusion is that modal interactions and associated modal shifts are unlikely to have a major impact on the need for or timing of infrastructure investment; or on the externalities associated with interstate freight transport. The impacts are likely to be small or swamped by other factors, such as the dominance of local and regional traffic on interstate highways, the existence of considerable spare capacity in railways and seaports and the dominance of passenger services in shaping airport infrastructure development. There are many subtle interactions between the modes both on an operational level and in terms of the market's response to the available transport options. Any follow-up studies should adopt an improved understanding of these modal interactions as a starting point and engender a holistic approach that flows from the identification and forecasting of demand through the complete chain of analysis.
