This study analyses travellers’ behavioural responses to two temporal measures implemented by the German government: the reduction in public transport prices, making it almost fare-free, and a decrease in fuel taxes to the minimum level permitted by European law. Based on a panel dataset of GPS-tracked trips collected before and during the price intervention from a representative sample of 276 individuals, ...
The study offers a comprehensive retrospective assessment of the Aviation Guidelines related to State Aid, evaluating their effectiveness and efficiency in promoting regional development and enhancing accessibility while minimizing competitive distortions. The analysis focuses on three primary areas: It examines whether the 2014–2024 transition period for phasing out operating aid to airports...
Road freight transport must switch to alternative drive technologies, such as battery-electric or hydrogen vehicles, to mitigate its impact on the climate. Preliminary results from an ongoing research project show that the fleet of battery-electric trucks as well as the number of models on offer have recently grown significantly, albeit from a very low level. This is not the case for hydrogen trucks. ...
Shared pooled mobility has been hailed as a sustainable mobility solution that uses digital innovation to efficiently bundle rides. Multiple disciplines have started investigating and analyzing shared pooled mobility systems. However, there is a lack of cross-community communication making it hard to build upon knowledge from other fields or know which open questions may be of interest to other fields. ...
Während Verkehrsinfrastruktur eine wichtige Rolle für die Entwicklung von Unternehmen und Regionen spielt, ist die Forschung zu den wirtschaftlichen Auswirkungen ihrer Instandhaltung äußerst spärlich. Diese Dissertation schließt diese Lücke vor dem Hintergrund, dass Unternehmen in Deutschland den Zustand der Straßen zunehmend als unzureichend empfinden. Erstens wird der Einfluss verschiedener Agglomerations- ...
This paper presents a data fusion approach combining German National Travel Survey data with aggregate transport indicators such as passenger counts in order to generate annual passenger kilometers travelled (PKT) for the German National Transport Statistics. To cover all travel adequately, the model combines two MiD data sets (a 24-hour-trip diary and an overnight journey questionnaire) and includes ...
The energy transition is a major challenge for both Germany and France. This Weekly Report provides an overview of the short- and long-term goals as well as current developments and trends in France’s energy and climate policy. It reveals that France is largely on track with its greenhouse gases targets and is also making good progress on installing heat pumps. However, its expansion of renewable energy ...
Greenhouse gas emissions must be reduced by 65 percent compared to 1990 by 2030 to achieve national climate targets. Nearly one third of greenhouse gas emissions in Germany are caused by private household consumption. Using Socio-Economic Panel (SOEP) data, this Weekly Report calculates the amount of CO2 equivalents emitted by households due to residential energy use, nutrition, and transport in Germany. ...
