Abstract
A continued shift of human mobility towards sustainable and active mobility modes is a major concern for society in order to reduce the human contribution to climate change as well as to improve liveability and health in urban environments. For this change to succeed, non-motorized modes of transport need to become more attractive. Cycling can play a substantial role for short to medium distances, but perceived safety and stress levels are still major concerns for cyclists. Therefore, a quantitative assessment of cyclists’ stress sensations constitutes a valuable input for urban planning and for optimized routing providing low-stress routes. This paper aims to investigate stress sensations of cyclists through quantifying physiological measurements and their spatial correlation as an intersubjective indicator for perceived bikeability. We developed an automated workflow for stress detection and aggregation, and validated it in a case study in the city of Salzburg, Austria. Our results show that measured stress generally matches reported stress perception and can thus be considered a valuable addition to mobility planning processes.

Even if there exist numerous possible factors influencing individual stress sensation that cannot be controlled, this research showed the general utility of physiological measurements for quantification of perceived stress in bicycle traffic
Summary
The high share of motorized vehicles leads to traffic congestion, high greenhouse gas emission, traffic noise, and air pollution. All this causes negative impacts on the environment, society and even individual health; see [1,2,3,4,5,6]. For short to medium distances, walking and cycling are valuable alternatives to motorized modes. These forms of mobility help reduce the problems stated above, but have a positive effect on individual health [7,8]
