The report discusses a new method for measuring the impact of human activities on ecosystems using the energy-flow concept. The methodology was found to meet most evaluation criteria for environmental analysis, with some areas for improvement. Compared to other methods, the energy-flow approach shows promise for enhancing environmental analysis. It was also shown to be useful for assessing transportation planning options without requiring extensive data or expertise. Overall, using energy-flow analyses for transportation planning is recommended, with suggestions for further development and practical application.
