Der Bestand an Pkw steigt stetig an. Die Nachfrage nach individueller Mobilität ist somit hoch und nimmt weiter zu. Die Herausforderung ist, das Auto klimaneutral zu gestalten. Vollelektrische Autos spielen hier eine zentrale Rolle. Dabei darf der Strombedarf nicht unterschätzt und muss für...

Die Pandemie stellt einen Einschnitt in der positiven Entwicklung des öffentlichen Verkehrs dar. Die Furcht der Nutzer:innen vor Infektionen könnte einen nachhaltigen negativen Effekt auf den öffentlichen Verkehr haben. Dieser Beitrag stellt Chancen und Potenziale des Mobility-as-a-Service...

Die Corona-Krise verändert auch den Stadtverkehr. Welche Chance bietet sich, die auf das Auto fixierte Verkehrsordnung grundlegend zu überholen?

In der umweltpolitischen Diskussion sind ökologische Verkehrsartenvergleiche sehr gefragt und werden für unterschiedlichste Zwecke verwendet. Für viele Fragestellungen waren die vorliegenden Datengrundlagen und Bewertungsansätze nicht mehr ausreichend. Ziel dieser Studie war daher die...

A central question in the analysis of fuel-economy policy is whether consumers are myopic with regards to future fuel costs. We provide the first evidence on consumer valuation of fuel economy from a natural experiment. We examine the short-run equilibrium effects of an exogenous restatement of...

When the zero lower bound on nominal interest rate binds, monetary policy makers may lack traditional tools to stimulate aggregate demand. We investigate whether "unconventional" fiscal policy, in the form of pre-announced consumption tax changes, has the potential to meaningfully shift durables...

In der aktuellen Diskussion um Alternativen zum privaten Fahrzeugbesitz spielen nachhaltige Mobilitätskonzepte wie Car- und Bikesharing-Systeme eine zentrale Rolle. Ihre Akzeptanz wird maßgeblich durch eine adäquate raum-zeitliche Verfügbarkeit der Fahrzeuge bestimmt. Daher stellt aus...

This database contains the full outputs from the analysis, which is also updated every other year in line with the publication. It covers the travel demand, vehicle activities, energy consumption, as well as related CO2 emissions of all modes (existing and new emerging modes) for both freight...

Personal automobile emissions are a major source of urban air pollution. Many U.S. states control emissions through mandated vehicle inspections and repairs. But there is little empirical evidence directly linking mandated inspections, maintenance, and local air pollution levels. To test for a...

Vor dem Hintergrund der hohen Komplexität der Finanzierung von Verkehrsinfrastruktur und -angeboten hat das Umweltbundesamt das Forschungsvorhaben "Ökonomischer Vergleich der Verkehrsträger" an Ernst Basler + Partner AG (Zürich), das Deutschen Institut für Wirtschaftsforschung (DIW Berlin)...

Der Tagungsband zum 9. Wissenschaftsforum Mobilität an der Universität Duisburg-Essen im Juni 2017 untersucht den Einfluss der fortschreitenden Digitalisierung auf traditionelle Automobilunternehmen und neue Mobilitätsanbieter. Die Beiträge des Forums an den Schnittstellen der...

This paper develops a dynamic, behavioral model with an explicit spatial structure to explore the co-evolutionary dynamics between infrastructure supply and vehicle demand. Vehicles and fueling infrastructure are complementarities and their chicken-egg dynamics are fundamental to the emergence...

This paper describes a method to characterize the fluctuating electricity generation of renewable energy sources (RES) in a power system and compares the different parameters for California and Germany. Based on this method describing the fluctuation and residual load, the potential contribution...
