This Paper contains basic information on the Australian road network, and on certain related data such as travel, expenditure, vehicle stock, and freight movement. The Paper is presented as a summary guide for ready reference to the status and trends of a limited range of road system characteristics. It includes data which the Bureau has found to be frequently used for the analysis of road systems, especially from the federal viewpoint. While the data presented here do not provide a complete picture, the aim has been to provide an overview description of the Australian road network, and it is anticipated that users will extract individual items of data according to their particular relevance.
