This Paper provides a description of the short-term forecasting models used in the Bureau's quarterly publication–Transport and Communications Indicators. For domestic freight, four models cover intercapital road freight, non-bulk government rail freight, bulk government rail freight and domestic air freight. Urban freight activity is not covered. For overseas trade there are also four models: bulk export tonnages, non-bulk import tonnages, air freight exports and air freight imports.

This Working Paper is the first in a series of Working Papers which disseminates the results of a large research project into the adequacy of Australia's transport infrastructure over the next 20 years. The assessment covers all four modes of transport–road, rail, air and sea–with the primary focus on freight.

Comparable figures are provided for the first time on emissions of greenhouse gases from the Australian transport sector in 1900 and 2000. Greenhouse emissions from the transport sector increased ten-fold twentieth century, but Australia's population has increased five-fold, and real GDP 23 times, while urban densities are now only about one third of those in 1900. Within the limits of long-term historical comparisons, it is concluded that use of the internal combustion engine itself has not contributed disproportionately to greenhouse emissions in the transport sector. However, electric vehicles would have been better. This paper was authored by Dr Leo Dobes.

This Report provides a 'business as usual' scenario for the emission of greenhouse gases from the Australian transport sector for the period 1993–94 to 2014–15. Models for emissions from cars, trucks, rail, sea and air transport reflect sectoral activity, fuel intensity and emission intensity factors.

Using the Bureau of Transport and Communications Economics' Road Infrastructure Assessment Model (RIAM), the Roads 2020 study makes forecasts at a strategic level of expenditure needs for investment and maintenance between 1998 and 2005 and between 2005 and 2020. It also indicates the locations and types of these expenditures. The forecasts cover non-urban roads and bridges which are either part of the National Highway System or are considered to be of national significance by the States and Territories. Expenditures predicted are upgrading road capacity (widening, adding lanes), town bypasses, maintenance, and bridge replacement. Some types of investment have been omitted because of data deficiencies or modelling difficulties. The exclusions are urban roads, flood mitigation projects, major realignment projects and widening roads used by road trains for safety reasons. Investments justified on social or equity grounds are also excluded. Traffic levels were forecast using population projections and origin-destination data. Total forecast expenditure needs for the National Highway System for the coming 22 year period have been estimated at $16.8 billion of which the backlog comprises $2.6 billion.
