We conducted a quasi-experimental research study to examine the impact of peer presence, peer familiarity, and peer group size on adolescent pedestrian risk-taking intentions in both sidewalk and street-crossing settings.<h4>Methods</h4>607 students aged 12-18 years from Nantong city, China, completed a questionnaire that presented 20 traffic scenarios.
