Children, as pedestrians, are at a higher risk of traffic accidents between the ages of 6 and 10, especially in urban areas, due to two main factors:

- **Short stature**: Children are shorter than adults, which limits their field of vision on the road. This means they cannot see approaching vehicles well, and at the same time, drivers have more difficulty seeing children. This visual limitation increases the risk of accidents.

- **Immature auditory system**: Although not explicitly mentioned in the texts, it can be inferred that, just as older people have trouble hearing vehicles due to environmental noise, children may also have auditory difficulties due to their immaturity. This can prevent them from detecting approaching vehicles, increasing the risk of being run over.

These factors, combined with a lack of attention and ignorance of traffic rules, make children especially vulnerable in urban environments, where traffic is denser and dangerous situations are more frequent.
