Resumen
Similar to other countries, Germany uses a national indicator set to monitor the progress of its sustainability strategy. As transport is one of the priority areas of a more sustainable development, this indicator system also includes a number of transport related indicators. After 10 years of using these transport indicators, the German Environment Agency contracted a scientific project to review their suitability. This paper describes the methodological approach taken within the project and the main results. A special consideration is thereby given to the commonly used modal split and transport intensity indicators. An assessment of the indicator practice within other European member states expands the national analysis and shows similarities and disparities in the indicator systems within Europe.
