Evaluating Vulnerable Road User Stress During Motor Vehicle Interactions in Urban Traffic Environments

The project aims to understand how interactions with motor vehicles and varying urban infrastructure conditions affect cyclists’ physiological stress responses. It focuses on urban cycling environments where cyclists share space with motor vehicles, considering different infrastructural contexts. The method involves analyzing physiological data (heart rate, heart rate variability, eye tracking), subjective responses, and performance data collected from the naturalistic part of the cycling experiment from the 24UNM03 project to quantify cyclists' stress responses. Using the integrated dataset, statistical models, likely Linear Mixed Effects Models (LMM), will be developed to quantify the relationship between micro-interactions and cyclist stress responses. This modeling approach accounts for both fixed and random effects, allowing examination of how individual variables influence outcomes while considering participant variability. The process aims to identify key stressors linked to infrastructure and vehicle behavior, translating findings into actionable insights for infrastructure design and safety interventions.
