With the help of a literature research, an overview of the vehicle concepts for air cabs presented so far and the possible flight missions is to be made. Which use cases are targeted by the manufacturers and which flight missions would be relevant from a transport perspective. In addition to the classification of vehicle types and thus feasible flight missions, the aim of the work is to research and assess market maturity. In addition to literature research, background discussions can also be held with experts.

Sustainability in road traffic is often reduced to ecological aspects. However, this study looks at all three dimensions - economic, ecological and social. Key indicators are identified by means of literature research and their interrelationships are examined. The aim is a holistic, empirically based assessment of sustainability in road traffic - independent of political buzzwords.

The thesis should evaluate and improve a draft concept of evaluation for Urban Air Mobility (UAM) systems. These include a review of proposed KPIs and indicators (based on DIN EN 13816). Next, the improved concept of evaluation should be applied to evaluate a simulated UAM service (the model will be provided). Recommendations for the industry and traffic planners should be derived.

The capacity of cycling facilities is stated very differently in the literature. The question is whether such a value is meaningful and which parameters should be taken into consideration at all. This paper therefore aims to carry out a comprehensive literature review on the capacity of cycle paths and then discuss whether the capacity for non-motorized road users is a meaningful, measurable parameter at all.

In this thesis, three goals are pursued: (1) to duplicate data and models from an existing (online) platform for (specified) offline studies, (2) to implement procedures to incorporate real-time data into testbed(s), and (3) to investigate data aggregation with respect to traffic control.

This bachelor thesis focuses on mode choice modeling and examines current statistical estimation methods. The focus is on the state-of-the-art approaches, the data used, and estimation techniques. Additionally, methods from literature that incorporate more than traditional survey data are analyzed, considering new data sources like mobile phone data or app tracking. Another key aspect is the integration of new mobility options, such as e-scooters, bikesharing, and carsharing, into mode choice models to better understand their impact on travel behavior.

In this thesis, the student examines ways of modeling destination choice of people. Destination choice models are a type of trip distribution or spatial interaction model which are formulated as discrete choice models, typically logit models. They can be thought of as a generalization of the traditional and widely used gravity model. The thesis will study different approaches and use a small test data set to conduct a destination choice model.

Cyclist models are based on model parameters that are compiled from reality. However, these are dependent on traffic scenarios and the cyclists themselves. In this work, previously defined parameters (e.g. speed or interaction radius) are to be searched for and compared in the literature.

People with physical or mental impairments are often disadvantaged while using mobility systems such as public transport. When it comes to automated on-demand bus services, the situation might get worse since no driver is aboard who could assist. This thesis should analyze the user acceptance of mobility impaired user groups of current and future public transport systems.

The focus of this work is a literature review of the characteristics of traffic with low lane discipline ("lane-less traffic") and a familiarization with one or more simulation programs for microscopic traffic flow simulation. Finally, the results and experiences must be presented and discussed in a structured way.

Based on a literature review, it is discussed whether artificial intelligence methods are suitable for calibrating a microscopic driving behaviour model. A conventional car following and lane change model can be used as a basis. Alternatively, a lane-free driving behaviour model for highly connected and automated driving can be used.

In this thesis, the student will conduct a comprehensive literature review and lane-free traffic control strategies. The review includes analysing the concept of each lane-free traffic strategy and to analyse the differences between these strategies and how each of them impacts traffic efficiency.
