Calculation of external costs for freight transport

摘要

The negative impacts of transport are in general associated with costs. These costs are usually denoted as 'external costs' or 'externalities'. This paper presents a tool for calculating external costs for freight transport together with its application to a number of case studies. The categories considered include: air pollution, greenhouse gases, noise, accidents and congestion. Results are presented for a number of different transport alternatives as total costs and divided into categories. The uncertainties in the results are discussed. The assessment of these costs is essential for predicting future transport costs.
