Individual travel behavior, such as mode choice, is determined to a distinct degree by the respective portfolio of available mobility tools, such as the number of cars, public transit pass ownership, or a carsharing membership. However, the choice of different mobility tools is interdependent, and individuals weigh alternatives against each other....

To make cities more sustainable and livable and to achieve climate targets in transportation, cities around the globe must undergo sustainable transformations. However, disparities in initial conditions pose challenges when trying to implement these sustainable changes. Identifying these differences aids in the comprehension of future developments....

Durch den Wegfall der Fahrtätigkeit in vollautonomen Fahrzeugen ergeben sich neue Möglichkeiten die Fahrzeit zu nutzen. In der vorliegenden Studie wird auf Basis einer Stated-Preference-Befragung untersucht, welchen Tätigkeiten sich Personen in autonomen Fahrzeugen widmen würden und wie sich diese von der heutigen Zeitnutzung im Öffentlichen Verkeh...

Als Reaktion auf das steigende Paketaufkommen werden neue, nachhaltige Konzepte der City-Logistik gesucht. Eine Lösung kann die Nutzung der bestehenden städtischen Schieneninfrastruktur über Cargo Trams sein. Um die verkehrlichen Wirkungen eines derartigen Konzepts quantifizieren zu können, wird in dieser Arbeit ein Güterverkehrsmodell für den Pake...

Recently, a substantial increase in parcel volumes has been observable, primarily shipped by courier, express, and parcel service providers (CEPSPs). Especially in urban areas, existing space conflicts are intensified, while emissions are steadily rising due to the higher need of parcel transportation. From a regional planning perspective, understa...

This paper considers which work-related trip patterns are included in household travel surveys and which in commercial travel surveys and if there are certain patterns that are distinctly underrepresented in either one. The study is structured as a comparison between data from a household travel survey and data from a commercial travel survey. Both...

The objective of this study is to investigate the role of spatial characteristics on car ownership and availability respectively in agent-based travel demand models and its affection on the model's results. Based on Open Data we generate an automated workflow to evaluate spatial characteristics such as land use, points of interest, private vehicle...

In Karlsruhe wurde 2021 mit dem EVA-Shuttle ein autonomer Kleinbus angeboten, welcher technologische Fort-schritte im Vergleich zu vergleichbaren Projekten vorwies. Im Rahmen einer Haushaltsbefragung zeigte sich, dass EinwohnerInnen dem Angebot aufgeschlossen gegenüberstanden. Die NutzerInnen weisen ein multimodaleres Verkehrsverhalten als Nicht-Nu...

Electric vehicles (EVs) can help to reduce greenhouse gas emissions of the transportation sector. Therefore, the German government has defined various measures and targets to promote the diffusion of EVs. However, factors influencing the market diffusion of EVs as well as interdependencies between policy measures and vehicle diffusion are often unc...
