This research effort presents a novel approach to measure cyclists’ stress: real-world, on-road measurements of physiological stress as cyclists travel across different types of bicycle facilities in various traffic volumes. This study addresses the question of how the characteristics of a bicycle trip affect stress levels using physiological data, specifically GSR. As detailed in the next section, GSR-based studies have been successfully employed for many years in the psychological field to recognize and associate emotions and behaviors to physiological responses. The three research questions examined in this study are: i) Does peak traffic impact cyclists’ stress levels? ii) Do intersections impact cyclists’ stress levels? and iii) Does facility type impact cyclists’ stress levels?
