Marginal costs of infrastructure use – towards a simplified approach

The main objective of this study carried out for DG TREN was to make the methodology to calculate marginal social costs easier accessible and more transparent to a broader group of users than just the inner circle of economist and transport experts involved in the research so far. The study covers three transportmodes (road, rail and aviation) and the following cost categories: infrastructure, air pollution, noise, accidents, congestion and scarcity. The study consists of two parts: (1) an overview of theoretical approaches and cost drivers and (2) an overview of simplified approaches to estimate marginal costs.
