This summary is the third in a series of five short documents based on a literature review published in 2011. In what follows, we first present the mechanisms of action underlying traffic-calming strategies, as these mechanisms help explain and predict the effects of such strategies on traffic noise. Next, we summarize the results of studies having evaluated two approaches to traffic calming. Lastly, we consider the implications of such results for public health.

The Coalitions Linking Action and Science for Prevention (CLASP) project is an initiative of the Canadian Partnership Against Cancer (CPAC).
