Children under a certain age don’t have the perceptual judgment and motor skills to cross a busy road consistently without putting themselves in danger, report researchers.
For the new study, children 6 to 14 years old participated in a realistic simulated environment and had to cross one lane of a busy road multiple times.
Children up to their early teenage years had difficulty consistently crossing the street safely, with accident rates as high as 8 percent with 6-year-olds. Only children who were 14 were able to navigate street crossing without incident. Children who were 12 mostly compensated for inferior road-crossing motor skills by choosing bigger gaps between cars…..

From the abstract:
This investigation examined developmental change in how children perceive and act on dynamic affordances when crossing roads on foot. Six- to 14-year-olds and adults crossed roads with continuous cross-traffic in a large-screen, immersive pedestrian simulator. We observed change both in children’s gap choices and in their ability to precisely synchronize their movement with the opening of a gap. Younger children were less discriminating than older children and adults, choosing fewer large gaps and more small gaps. Interestingly, 12-year-olds’ gap choices were significantly more conservative than those of 6-, 8-, 10-, and 14-year-olds, and adults. Timing of entry behind the lead vehicle in the gap (a key measure of movement coordination) improved steadily with development, reaching adultlike levels by age 14. Coupled with their poorer timing of entry, 6-, 8-, and 10-year-olds’ gap choices resulted in significantly less time to spare and more collisions than 14-year-olds and adults. Time to spare did not differ between 12-year-olds, 14-year-olds, and adults, indicating that 12-year-olds’ more conservative gap choices compensated for their poorer timing of entry. The findings show that children’s ability to perceive and act on dynamic affordances undergoes a prolonged period of development, and that older children appear to compensate for their poorer movement timing skills by adjusting their gap decisions to match their crossing actions. Implications for the development of perception–action tuning and road-crossing skills are discussed.
