Development of an Interactive Front-End Tool for a GNN Surrogate Model to Evaluate Urban Traffic Measures.
Mentoring: Natterer.The goal of this thesis is to develop an interactive front-end tool capable of visualizing the effects of traffic policies. At its core, the tool leverages a Graph Neural Network (GNN)-based surrogate model that enables rapid simulations. The aim is to provide decision-makers and citizens with an intuitive platform to test various traffic measures in different urban areas and scales. The impacts of these measures should be displayed accurately and in a visually appealing way. Tasks include selecting a suitable framework (e.g., React, Dash, or Streamlit), seamless integration of the surrogate model, and developing user-friendly visualizations. The tool should be fully operational and ready for practical use. Strong programming skills are a prerequisite for this thesis.

Influence of Cycling and Traffic Environments on Attention Patterns.
Mentoring: Takayasu.Aligning with micromobility promotion policies in many European cities, ensuring the safety of cyclists has become an increasingly important topic. Despite growing attention, objective investigations of cyclist behavior are still under development and remain limited in scope. This thesis aims to explore attention patterns during cycling by analyzing eye-tracking data. Measures such as fixation locations and durations, blink rates, and head movements will be compared between different conditions: riding a bicycle and sitting at the roadside as a passive observer. Furthermore, attention patterns will be contrasted between distinct environments, including busy traffic roads and calm park streets, in order to assess the influence of environmental context. The comparison will provide insights into how the dynamic task of cycling and the surrounding environments influence visual attention, situational awareness, and cognitive load. The findings are expected to enhance the understanding of cyclist behavior in real traffic conditions. The results can support the design of safer cycling infrastructure and inform policy strategies that foster micromobility-friendly urban development.

Simulationbased analysis of parking strategies for automated ride-pooling services.

Simulation of On-Demand Fleets with MFD-Based Dynamic Network Models.
Mentoring: Dandl.Many studies of on-demand mobility services assume constant travel times as their focus is on operational algorithms rather than traffic dynamics. FleetPy is a modular framework to simulate on-demand services and by default also uses deterministic travel times. The goal of this thesis is to adapt the network model within FleetPy to be dynamic and efficient; more specifically, a dynamic MFD-based model will be implemented in this thesis. Thereafter, the thesis will analyze fleet performance indicators for both deterministic and dynamic scenarios, as well as study the impacts of traffic congestion caused by ODM on mode choice.

Lane-Free Traffic Control Strategy for Mixed Traffic of Human and Connected Autonomous Vehicles (CAVs).
Mentoring: Syed.With the introduction of Connected Autonomous Vehicles (CAVs), there is a growing interest in Lane-Free Traffic (LFT), where CAVs drive without managed lanes. The movement of CAVs in LFT is controlled by control algorithms that coordinate their movements. However, the performance of this controller can be severely affected by the presence of human drivers. Therefore, this thesis develops a control strategy for CAVs capable of dealing with mixed traffic where humans and CAVs share the same road without degrading the performance of CAVs in LFT. The simulation will be conducted in a customized SUMO for LFT and requires some basic programming skills in C++.
