In der verkehrspolitischen Diskussion werden bedarfsgesteuerte Angebotsformen des öffentlichen Personennahverkehrs (ÖPNV) vielfach als geeignete Ergänzung des sich in nachfrageschwachen Räumen ausdünnenden traditionellen ÖPNV betrachtet, um auf den Qualitätsnachteil gegenüber dem...

Many governments subsidize regional rail service as an alternative to road traffic. This paper assesses whether increases in service frequency reduce road traffic externalities. We exploit differences in service frequency growth by procurement mode following a railway reform in Germany to...

The COVID-19 crisis has identified several weaknesses and shortcomings of global supply chain networks. Due to the rapidly increasing demand of protective healthcare equipment, i.e. goggles, masks or equipment, it is visible that global supply chains have been significantly challenged....

This study analyzes the effects of binding speed limits on crash frequency on German motorways. Various geo-spatial data sources are merged to a new data set providing rich information on roadway characteristics for 500-meter segments of large parts of the German motorway network. The empirical...

We study the short-term effects of the 9-Euro-Ticket, a major German public transport subsidization program, on particulate matter (PM). Using hourly PM readings from pollution monitoring stations throughout Germany, provided by the German Federal Environmental Agency, we find declines in...

In the European Union (EU) and in Germany the transport sector is the only sector with increasing CO2 emissions (in the EU by about 32 % and in Germany by about 1 % since 1990). Especially in road freight and air transport a further strong increase is forecasted. In the transport sector this...

Competitive tendering of local bus services in Germany has received increased attention. Employing Seemingly Unrelated Regression analyses, we observe that prices have regionally varying determinants; for example, while prices throughout most of the federal state of Hesse increase over time,...
