Research profile

The research group “Transport Economics” analyses transport markets and the related infrastructure. Most of this research aims at providing empirical and methodological foundations for pricing and investment decisions in the transport sector. One focus is the analysis of cost structures and cost functions for providing and maintaining transport infrastructure as a basis for deriving conclusions on marginal cost pricing for the use of transport infrastructure. A further topic refers to the question whether and to what extent neglected infrastructure (under-maintenance) affects productivity and economic growth. Valuation of non-market goods (noise, accidents, congestion, reliability, air pollution, global warming) is a further research topic which is important for pricing and investment policy in the transport sector, whereby our focus is on noise and accidents. Another research field is the analysis of competition and efficiency of using subsidies (the so-called regionalization subsidies granted by the Federal Government to the Länder) in regional rail passenger transport.

Furthermore, the research group analyses trends of transport demand. These studies are based on survey data and statistics. The results are used for studies on technologies, fuels and environmental impacts of mobility. Within the annual compendium „Transport in Figures“, the research group regularly elaborates data both for own research and policy advice and for the public. This includes a detailed compilation of investments in all modes of transport and modelling work using the perpetual inventory method to obtain detailed capital stock figures for all transport modes.
