In sustainable mobility, cycling plays a central role. However, environmental factors such as road conditions, traffic infrastructure, and noise significantly influence cyclists' sense of safety and thus their use of bike paths. Major roads, intersections, and uneven surfaces, in particular, compromise the safety and comfort of cyclists, which can be measured in terms of increased stress. Demographic factors such as gender and age are also critical, as women and older cyclists are especially vulnerable to stressful traffic situations.

For any participating partner or municipality, a test route is developed. First, the mobility infrastructure is mapped. Then, a sample group is selected, followed by defining a starting point at a busy location or important destination, such as a school. Participants are recruited through various channels, including online ads and personal invitations. The participation criteria include being between 18 and 70 years old and able to ride a bicycle.

During the ride, stress levels, noise levels, and environmental characteristics are measured, and the surroundings are recorded with a geo-referenced camera—meaning the images can later be linked to coordinates, allowing stress triggers to be identified. Stress is measured using a smart band developed in 2024 at the University of Salzburg in collaboration with the Karlsruhe Institute of Technology (KIT). This device records skin conductance and temperature, while noise levels are captured with a special sensor. The study differentiates between regular bicycles, e-bikes, and pedelecs.

The data is analyzed using regression analysis in Geographic Information Systems (GIS) to examine the relationship between road features, traffic conditions, and stress. Individual characteristics such as age, gender, and cycling frequency are also included in the analysis. The study forms the basis for further recommendations to improve both the objective and perceived safety of the tested cycling routes.

In addition to this specific project proposal mapping safe cycling routes, I am interested in urban greening and climate adaptation through nature-based solutions.
