This study compares the environmental impacts of urban public transport and automobiles (energy use, emissions, noise nuisance, waste materials and use of space). For this purpose two models have been developed FACTS-Urban (Forecasting air pollution by car traffic simulation) and MILOV...

Private motorised vehicles account today for 90% of total surface transport1 CO2 emissions. Car fleets are growing rapidly in many cities in the developing world, where population and income growth will be concentrated in the coming decades. For example, whilst urban agglomerations with more...

In this paper we develop a framework to value public investments with the purpose of increasing bicycling that explicitly accounts internal costs of bicycling, which are typically neglected in current established approaches that value bicycle spending by means of gross health benefits alone, as...

Gegenwärtig weist der Öffentliche Personennahverkehr (ÖPNV) in Deutschland ein beträchtliches Maß an ökonomischer Ineffizienz auf. Ausschlaggebend dafür ist die starke Einflußnahme des Staates auf diesen Verkehrsbereich: Der ÖPNV wird staatlich reguliert und sein Leistungsumfang zu...

This text analyzes Brazilian families spending with public and private urban transport based on family budget surveys conducted by IBGE in 2003 and 2009. It was observed that on average Brazilian families spend about 15% of their income on urban transportation. Private transport expenses are...

Der Begriff Intermodalität hat in den Verkehrswissenschaften verschiedene Bedeutungs-kontexte, die häufig nicht trennscharf verwendet werden. Die verschiedenen Dimensionen von Intermodalität sind: 1.) die Beschreibung von Verkehrssystemen im Güterverkehr, 2.) die Beschreibung von...

Die diesem Paper zugrundeliegende Ausgangsannahme ist, daß ein sozialwissenschaftliches Innovationskonzept zur Erklärung umweltentlastender Verhaltensänderungen besonders gut geeignet ist. Es kann gezeigt werden, daß in Anlehnung an ein derartiges Konzept eine theoretisch und praktisch...

We model the choice of transportation mode in a simplified Hotelling-like city, with a fixed number of total travellers, fixed road capacity and with no trade-off between when to travel and the time spent in a queue. A person that chooses to take her own car will inflict a congestion cost on all...

The possible consequences of the advent of fully automated vehicles (AVs) for personal transport are assessed. A shared-user model is considered preferable to an owner-user model; public-sector intervention is considered necessary to secure the successful integration of AVs with mass transit....
