The aim of the Australian Infrastructure Statistics Yearbook is to provide a single, comprehensive annual source of infrastructure statistics for use by policymakers, industry leaders, transport analysts and the wider Australian community.
The publication is primarily a source of long-term, aggregate time series infrastructure statistics. In most cases the time series extend to 2014–15. Most statistics included in the publication are currently collected by BITRE or other Australian, state or territory government agencies.
The Australian Infrastructure Statistics Yearbook provides comprehensive and coherent time series statistics on major Australian infrastructure and its use.
The Yearbook is presented in five parts.
Part I of the Yearbook provides a summary of major economic infrastructure and several statistical measures of factors that relate to investment in and use of major economic infrastructure.
The rest of the Yearbook is divided into four sections, focussing on each of the four themes of major economic infrastructure:
• Part T, for transport infrastructure;
• Part E, for energy infrastructure;
• Part C, for communications infrastructure; and
• Part W, for water infrastructure.
The yearbook covers four key areas.
• Physical infrastructure - Measures include the value and capacity of infrastructure at a given time (‘stock’ measures); additions to the amount of infrastructure (construction) and reductions (depreciation) that take place during the year (‘flow’ measures); and measures of the quality of the infrastructure.
• Inputs - Measures of non-capital inputs to activities that rely on infrastructure.
• Activity - Measures of activities associated with infrastructure. For transport, this includes freight and passenger movements, and road, rail, aviation and maritime activity.
• Impacts - Measures of the external impact of activities. These impacts include safety and security issues as well as greenhouse gas emissions and other pollution.
Each of the chapters in the yearbook cover these four key areas
