Objective: Pedestrian injuries are a major cause of morbidity and mortality to children, especially boys. Adults serve as pedestrian role models and provide learning opportunities to children when walking to school. The research objectives were to investigate adult pedestrian behaviour when accompanying boys and girls.Methods: Behavioural observation of 140 adult pedestrians accompanying 4 -9 year-old children was done in British residential locations. Observations took place at light-controlled crossings, speed restricted school safety zones and mid-block unmarked crossing sites.Behaviours observed included stopping at the curb, waiting at the curb, looking left and right before and during road crossing, holding hands, talking, and walking straight across. Results:In general, adults modeled safe road crossing behaviours. Adult safe behaviour scores were higher when accompanying girls than when accompanying boys. No statistically significant differences were found by child age group. The fewest safe pedestrian behaviors were observed at light-controlled crossings. Conclusions:Adult pedestrians behave differently when with boys and girls and at different types of road crossing site. Interventions aimed at reducing pedestrian injuries to children may need to take these different everyday experiences into consideration.
