Proximity to Highways

Measurement Period: 2020
This indicator shows people living within 150 meters (about two blocks) from a major highway. For this indicator, a "highway" is defined as a major roadway or freeway that connects inter-state and inter-metropolitan areas and is defined as either a class 0,1, or 2 roadway by the Federal Highway Administration (FHWA) Functional Classification System.

Why is this important?

Traffic-related pollutants are highest in the near-road environment. People who live closest to a major highway are more likely to be exposed to traffic-related air pollution resulting in an unhealthy air quality. 
According to the Centers for Disease Control and Prevention, exposure to traffic-related air pollution is associated with asthma exacerbation as well as childhood asthma, non-asthma respiratory symptoms, impaired lung function, all-cause mortality, cardiovascular mortality, and cardiovascular morbidity.
