Examining the impact of traffic environment and executive functioning on children's pedestrian behaviors.

The process of integrating visual information and planning a safe crossing is cognitively demanding for many young children. We assessed relations between traffic characteristics, aspects of children's executive functioning (EF), and pedestrian behavior, with the aim being to determine whether well-developed EF would predict safer pedestrian behaviors beyond the contributions of child demographic and traffic environment factors. Using the pretend road method, we studied a sample of 83 children aged 6-9 in a series of 5 crossing trials beside a real road in response to actual traffic conditions. Traffic characteristics and pedestrian behaviors were observed and measured across crossing trials. Both traffic characteristics and EF, most notably cognitive efficiency, were strongly related to children's pedestrian crossing behaviors. Traffic characteristics were also found to interact with children's ability to monitor their crossing performance. Examining developmental influences in pedestrian injury etiology broadens researchers' knowledge of and ability to prevent injuries by moving beyond describing what happens to children and examining why pedestrian injuries occur.
