The current focus of transportation policy around disruptive events is to adopt an engineering resilience-oriented approach, which focuses on returning assets to good workable order as soon as possible. This will remain critically important in the future to reduce the scale and severity of...

The challenges facing transportation planners have grown continuously over the years owing to mounting problems of congestion, concerns with environmental degradation and global warming, enhanced awareness of safety, and the increasing complexity of travel behaviour patterns associated with...

Biofuels have been the only alternative fuel which has substantially contributed to supplying transport with energy. Biofuels enjoyed broad support, but now they have come under criticism. In order to obtain answers to the question of what role biofuels could play in the future fuel mix, the...

Biokraftstoffe galten einst als grüner Hoffnungsträger für eine nachhaltigere Automobilität. Mit verstärktem Einsatz gerieten sie jedoch zunehmend in die Kritik. Dennoch bleiben Biokraftstoffe die wichtigste Alternative zu fossilen Kraftstoffen. Die Autoren diskutieren die Rolle der...

Do drivers reduce speeds when gasoline prices are high? Previous research investigating this energy conservation hypothesis produced mixed results. We take a fresh look at the data and estimate a significant negative relationship between speeding and gasoline prices. This presents a new...

Do negative incentives or sticks in education improve student outcomes? Since the late 1980s, several U.S. states have introduced No Pass No Drive (NPND) laws that set minimum academic requirements for teenagers to obtain driving licenses. Using data from the American Community Survey (ACS) and...

Transport, insbesondere der Straßenpersonenverkehr, verursacht massive Umweltauswirkungen und Treibhausgasemissionen, die bisher nur unzureichend politisch bekämpft wurden. Gerade Deutschland mit seiner starken Automobilindustrie und dem gut ausgebauten Straßennetz ist hier keine Ausnahme....

A brief review of long run projections of demand for road transport suggests that problems related to road network congestion and greenhouse gas emissions are likely to become more pressing than they are now. Hence we review, from a macroscopic perspective, popular policy measures to address...

PHEVs are discussed controversially. On the one hand, the evolutionary approach of a hybrid vehicle helps the consumer to adopt to electric driving, using the range extender when driving longer distances. On the other hand, PHEVs have a more complex propulsion system and a potentially low...

This study establishes a new approach to analyzing the economic impacts of vehicle-to-grid (V2G) regulation by simulating the restrictions arising from un-predictable mobility requests by vehicle users. A case study for Germany using average daily values (in the following also called the...

Als Rebound-Effekt werden Verhaltensänderungen bezeichnet, durch die Energieeinsparungen infolge von Energieeffizienzverbesserungen teilweise oder gar gänzlich wieder aufgezehrt werden. Dieser Artikel untersucht die Heterogenität des Rebound-Effektes bei der privaten PKW-Nutzung auf Basis von...

We analyze the expected effects of building a rail tunnel between Lyon and Turin on i) the market shares of the established and the new suppliers, and ii) consumer surplus. The prospective project consists of a 53km rail tunnel providing freight shippers with a new alpine path. We calibrate an...

In studying congestion tolling, it is important to account for heterogeneity in preferences of drivers, as ignoring it can bias the welfare gains. We analyse the effects of tolling, in the bottleneck model, with continuous heterogeneity in the value of time and schedule delay. The welfare gain...

Unreliable travel times cause substantial costs to travelers. Nevertheless, they are not taken into account in many cost-benefit-analyses (CBA), or only in very rough ways. This paper aims at providing simple rules on how variability can be predicted, based on travel time data from Dutch...

We estimate a revealed-preference scheduling model of morning peak behaviour that allows us to determine the impact of traffic information on traveller behaviour. Specifically, we distinguish between the marginal impact of expected travel times versus that of deviations from this expectation...
