Data Interpretation Issues

Proximity to a highway is a surrogate for exposure to traffic-related air pollution. The size of potential exposure zones and levels of exposure can vary considerably depending on the pollutant, traffic volume, ambient pollution concentrations, meteorological conditions, topography, and land use.

Why Is This Important?

Motor vehicles are a major source of air pollution in the United States. Research suggests that particulate matter (PM) from vehicles, notably heavy-duty diesel vehicles, may be especially harmful. [[br]][[br]] Motor vehicle pollutant concentrations tend to be higher closer to the road, with the highest levels generally within the first 500 feet of a roadway and reaching background levels within approximately 2,000 feet of a roadway, depending on the pollutant, time of day and surrounding terrain. 3.2% of Utahns, or 88,505 people, lived within 150 meters (492 feet) of a highway. [[br]][[br]] Nearly 17,000 schools in rural and urban areas across the U.S. are located near heavily traveled roads. There are 33 public schools in Utah that are located within 150 meters of a highway. Kane County has the highest percentage of schools (27.3%) that are located within 150 meters of a highway. [[br]][[br]] Exposure to traffic-related air pollution has been linked to a variety of short- and long-term health effects. Children are particularly sensitive to air pollution, because their respiratory systems are not fully developed, they are more active, and they breathe more rapidly than adults. Children also are more likely than adults to have asthma.
