The Transport for NSW is committed to achieving greater value for money from our significant investment in transport assets and to improving the efficiency and quality of transport services.
4 The conduct of Economic Appraisal provides evidence that aids sound decision making towards making these investments. The TFNSW Principles and Guidelines for Economic Appraisal of Transport investment and Initiatives sits within the Transport investment Policy Framework and aims to help managers across the Transport Cluster to plan and conduct Economic Appraisal based on a consistent framework. The use and application of the Guidelines facilitate evaluation of Economic efficiency of investment proposals and contribute to improved resource allocation by ensuring that the strategic alignment and value for money assessment have been consistently determined across the Transport cluster.
5 The Guidelines set out the Principles , concepts, methodology and procedures to be used in the evaluation of proposed investments and initiatives in the transport cluster. Analytical steps, illustrative calculations, practice guides and advice and references to reports and tools are provided. User friendly models and tools have been developed covering prototype transport projects to assist in cost benefit analysis of similar projects. The links to these calculation models are embedded in the document to make them accessible to users. Economic parameter values are provided for consistent use across the Transport Cluster. These are updated on an annual basis and are disseminated to the whole cluster for continued and consistent application.
6 Both instructor-based and online training modules are provided including demonstrations and customised case studies on the application of Economic Appraisal methods and models to particular projects, programs or activities in the work areas. The Economic Appraisal Guidelines is a living document that is continuously being reviewed and updated to enhance its relevance and ensure adherence to best practice. New methodologies are included as they become relevant to ensure that Transport is at the leading edge of robust, transparent decision making and driving value for money.
