Urban Traffic Calming and Road Safety: Effects and Implications for Practice

This summary is the first 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 to explain and predict the effects of calming interventions on the number and severity of collisions. Next, we summarize the results of studies having evaluated two approaches to traffic calming
