Air pollution is a major concern for public health. Among the studies conducted to evaluate the association between air pollution and a wide variety of outcomes, some have used motor vehicle traffic data as a method for exposure assessment. This paper intends to revise and discuss some of the methodological aspects of studies that used this method, especially in areas where vehicles are the main generating source of pollutants. We performed a literature search with keywords related to air pollution and vehicle traffic, and selected articles published between the years 2000 to 2009. We noted different approaches for assessing the exposure among the studies using vehicle traffic, with emphasis on the method named Distance Weighted Traffic Density, which considers the number of roads, the distance from the location of interest and traffic itself. Moreover, we highlight the importance of using techniques such as geographic information systems (GIS) to measure this exposure.
