Linking Traffic and Distance to Roads with Pollution and Health Effects
- Pregnant women who resided within approximately 300 m of a freeway either during their last trimester of pregnancy, or at the time they delivered, gave birth to children who were at twice the average risk of being autistic.
- Children who lived within 500 m of a freeway from ages 10 to 18 experienced substantial deficits in lung function development compared to similarly aged children who lived at least 1500 m from a freeway.
- Living near a freeway is a strong predictor of traffic-related pollution (TRP). Compared with living at least 1500 m from a freeway, living within 250 m of a freeway was associated with up to a 41% increase in TRP in a large urban area, and up to a 75% increase in small urban areas. Thus, traffic strongly affects local air quality in large and small urban areas.
